AD7656 General Description

The AD7658/AD7657/AD7656 contain six 12/14/16-bit, fast, low power, successive approximation ADCs all in the one package. The AD7658/AD7657/AD7656 core operates from a single 4.75 V to 5.25 V power supply and features throughput rates up to 250 kSPS. The parts contain low noise, wide bandwidth track-andhold amplifiers that can handle input frequencies up to 8 MHz.

The conversion process and data acquisition are controlled using CONVST signals and an internal oscillator. Three CONVST pins allow independent simultaneous sampling of the three ADC pairs. The AD7658/AD7657/AD7656 have both a high speed parallel and serial interface allowing the devices to interface with microprocessors or DSPs. When in Serial interface mode these parts have a Daisy Chain feature allowing multiple ADCs to connect to a single serial interface. The AD7658/AD7657/AD7656 can accommodate true bipolar input signals in the ±10V range and ±5V range . They contain a 2.5V internal reference and can also accept an external reference. If a 3V external reference is applied to the VREF pin, the ADCs can accommodate a true bipolar ±12V analog input range. VDD and VSS supplies of ±12V are required for this ±12V input range.
