The AD7851AR is an IC (integrated circuit) component manufactured by Analog Devices. It is a complete, low power, and low noise, 12-bit analog-to-digital converter (ADC). The IC is capable of digitizing analog signals with high precision and accuracy, making it suitable for various applications in measurement and control systems.
Some of the key features of the AD7851AR include:
1. Resolution and Sampling Rate: The AD7851AR offers a 12-bit resolution, which means it can convert an analog input signal into 4096 discrete digital output values. It provides a fast conversion rate of up to 1 megasample per second (MSPS), allowing for real-time data acquisition.
2. Input Channels: It features a single-ended analog input configuration with eight input channels, enabling simultaneous conversion of multiple analog signals. The input voltage range can be set between 0V and VREF, where VREF is the reference voltage supplied externally.
3. Signal Conditioning: The ADC incorporates a fully differential input structure, providing enhanced signal conditioning capability. This allows for the digitization of both single-ended and differential voltage signals with high accuracy.
4. Serial Interface: The IC utilizes a versatile serial interface, compatible with standard microcontrollers, microprocessors, and digital signal processors (DSPs). It supports both serial peripheral interface (SPI) and microcontroller/microprocessor serial interface (µP) modes, offering flexibility in communication with external devices
