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.
-55°C~125°C
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.

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.

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.

Operating Supply Current
Operating Supply Current is the amount of current drawn by an electronic component when it is operating under normal conditions. It is typically measured in milliamps (mA) or microamps (µA). The operating supply current is important because it can affect the power consumption of the component and the overall system. A higher operating supply current will result in higher power consumption, which can lead to overheating and reduced battery life.
54mA
Power Dissipation
Power Dissipation is the maximum amount of power that an electronic component can safely dissipate without being damaged. It is typically measured in watts (W) and is determined by the component's physical size, material properties, and design. Exceeding the power dissipation rating can lead to overheating, reduced performance, and even component failure.

Data Interface
Data Interface refers to the physical and logical means by which an electronic component communicates with other components or systems. It defines the protocols, pinouts, and signal characteristics used for data exchange. The Data Interface parameter specifies the type of interface supported by the component, such as SPI, I2C, UART, or Ethernet. It ensures compatibility and proper communication between different devices within a system.
Serial
Sampling Rate
Sampling rate refers to the number of times per second that an analog signal is measured and converted into a digital signal. It is expressed in Hertz (Hz) and determines the maximum frequency that can be accurately represented in the digital signal. A higher sampling rate results in a more accurate representation of the analog signal, but also increases the amount of data that needs to be processed. The sampling rate must be at least twice the highest frequency component of the analog signal to avoid aliasing, where high-frequency components are incorrectly represented as lower-frequency components.

Description
The AD7403-EP is a high-performance, second-order, sigma-delta modulator that converts an analog input signal into a high-speed, single-bit data stream. It features on-chip digital isolation based on Analog Devices' iCoupler technology. The device operates from a 5 V power supply and accepts a differential input signal of ±250 mV (±320 mV full-scale). The differential input is ideally suited for shunt voltage monitoring in high voltage applications where galvanic isolation is required.
The analog input is continuously sampled by a high-performance analog modulator and converted to a ones density digital output stream with a data rate of up to 16 MHz. The original information can be reconstructed with an appropriate digital filter to achieve 88 dB signal-to-noise ratio (SNR) at 78.1 KSPS.
The serial interface is digitally isolated. High-speed complementary metal oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, means the on-chip isolation provides outstanding performance characteristics, superior to alternatives such as optocoupler devices.
