The AD7872ANZ is a high-precision, dual-channel, analog-to-digital converter (ADC) integrated circuit (IC) manufactured by Analog Devices. It offers exceptional accuracy and resolution, making it suitable for a wide range of data acquisition and conversion applications. Here's an overview of its key features:
1. Dual-Channel ADC: The IC incorporates two independent ADC channels, allowing simultaneous conversion of two analog input signals. Each channel operates at a maximum sample rate of 2.5 kilosamples per second (ksps).
2. Resolution and Accuracy: The AD7872ANZ boasts impressive resolution with a 12-bit architecture, ensuring precise conversion of analog signals into digital data. It provides excellent accuracy with a maximum total unadjusted error of ±1 LSB.
3. Input Range: The IC can accept analog input signals within a bipolar voltage range of ±10 volts. This wide input range enables the conversion of various signals, making it highly versatile.
4. Flexible Input Selection: It offers flexible input channel selection with a dedicated multiplexer, enabling the AD7872ANZ to handle multiple analog input sources efficiently. The multiplexer provides 16 input channels, including eight externally programmable differential inputs.
5. Serial Interface: The IC utilizes a standard 3-wire serial interface (clock, data in, and data out) that is compatible with both SPI and MICROWIRE protocols. This interface allows seamless communication with microcontrollers and other digital devices
