Mounting Type
Mounting Type refers to the method by which an electronic component is attached to a printed circuit board (PCB) or other surface. Common mounting types include:
* Through-hole: Component leads are inserted into holes in the PCB and soldered on the other side.
* Surface-mount: Component is placed on the surface of the PCB and soldered in place.
* Press-fit: Component is pressed into place on the PCB without soldering.
* Socket: Component is inserted into a socket on the PCB, allowing for easy replacement.
The mounting type is determined by factors such as the component's size, shape, and power requirements.
Surface Mount
Package / Case
Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

Number of Pins
Number of Pins: Indicates the number of electrical connections available on the component. These pins are used to connect the component to other components or circuits on a printed circuit board (PCB). The number of pins determines the functionality and connectivity options of the component. It is important to ensure that the component has the correct number of pins for the intended application.

Operating Temperature
Operating Temperature is the range of temperatures at which an electronic component can function properly. It is typically specified in degrees Celsius (°C) and indicates the minimum and maximum temperatures at which the component can operate without experiencing damage or degradation. Operating Temperature is an important parameter to consider when designing electronic circuits, as it ensures that the components will function reliably in the intended operating environment.

Part Status
Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.
Obsolete
Moisture Sensitivity Level (MSL)
Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

Technology
Technology, in the context of electronic components, refers to the specific manufacturing process and materials used to create the component. It encompasses the semiconductor fabrication techniques, such as the type of transistor used (e.g., MOSFET, BJT), the gate oxide thickness, and the interconnect materials. Technology also includes the packaging type, such as surface mount or through-hole, and the leadframe or substrate material. The technology used impacts the component's performance characteristics, such as speed, power consumption, and reliability.

Output Type
Output type refers to the type of signal or power that an electronic component can produce. It can be analog or digital, AC or DC, and can vary in voltage, current, or power levels. The output type is determined by the component's design and is crucial for matching it with other components in a circuit. Understanding the output type ensures proper signal processing, power delivery, and overall system functionality.

Number of Channels
Number of Channels refers to the number of independent signal paths within an electronic component. It indicates how many separate signals can be processed or transmitted simultaneously. For example, an audio amplifier with two channels can amplify two separate audio signals, while a multi-channel data converter can convert multiple analog signals into digital data. The number of channels is a crucial parameter for determining the component's functionality and application.

Quiescent Current
Quiescent current is the amount of current drawn by an electronic component when it is not actively performing its intended function. It is typically measured in milliamps (mA) or microamps (µA). Quiescent current is important because it can affect the overall power consumption of a circuit, especially in battery-powered devices. Components with high quiescent current can drain batteries more quickly than those with low quiescent current.

Output Power
Output Power is a measure of the electrical power delivered by an electronic component to a load. It is typically expressed in watts (W) or milliwatts (mW). The output power of a component is determined by its design and the voltage and current applied to it.
Output power is an important parameter for many electronic components, such as amplifiers, power supplies, and transmitters. It is used to determine the component's efficiency and to ensure that it can provide enough power to drive the load.

Length
Length, in the context of electronic components, refers to the physical dimension of a component along its longest axis. It is typically measured in millimeters (mm) or inches (in). Length is a crucial parameter for determining the physical size and space requirements of a component on a printed circuit board (PCB) or other assembly. It also affects the component's electrical characteristics, such as inductance and capacitance, which can be influenced by the length of conductors or traces within the component.

Description
The TPA0122 is a stereo audio power amplifier in a 24-pin TSSOP thermally enhanced package capable of delivering 2.6 W of continuous RMS power per channel into 3-2 loads. This device minimizes the number of external components needed, simplifying the design, and freeing up board space for other features. When driving 1 W into 8-2 speakers, the TPA0122 has less than 0.5% THD N across its specified frequency range.
Included within this device is integrated depop circuitry that virtually eliminates transients that cause noise in the speakers. Amplifier gain is internally configured and controlled by two terminals (GAINO and GAIN1). BTL gain settings of 2, 6, 12, and 24 V/V are provided, while SE gain is always configured as 1 V/V for headphone drive. An internal input MUX allows two sets of stereo inputs to the amplifier. In notebook applications, where internal speakers are driven as BTL and the line outputs (often headphone drive) are required to be SE, the TPA0122 automatically switches into SE mode when the SE/BTL input is activated and reduces the gain to 1 V/V.
The TPA0122 consumes only 18 mA of supply current during normal operation. A miserly shutdown mode reduces the supply current to less than 150 μA. The PowerPAD package (PWP) delivers a level of thermal performance that was previously achievable only in TO-220-type packages. Thermal impedances of approximately 35°C/W are truly realized in multilayer PCB applications. This allows the TPA0122 to operate at full power into 8-2 loads at an ambient temperature of 85°C.
