AD7879ACBZ-RL Overview
A Tape & Reel (TR) package is used to house this item.It was included in the 16-VQFN Exposed Pad, CSP package that was sent out.The device adapts a SPI interface to improve the performance of data acquisition.It is mounted in the Surface Mount axis of the machine.As this unit is designed to read the supply voltage as 1.6V~3.6V, you better redo the circuit if you are not able to read it.For this chip, the average operating temperature should be -40°C~85°C degrees Celsius.The total number of terminals is 12, and each of them has its own set of functions.In this case, AD7879 is the base part number for the device.The part has a total of four 12 pins in total.As a result, it provides a voltage reference for External.This data acquisition device has 12-pin connectors suitable for a variety of applications.In order to enhance the flexibility of this product, Surface Mount has been adapted.The device is capable of acquiring high-resolution 12-bit data.The supply voltage of 2.6V is recommended in order for this gadget to run properly.The acquisition of high-level analog sources is achieved by implementing an analog input channel with a 2 value.
