AD7656/AD7657/AD7658
16-/14-/12-BIT SAR

GENERAL DESCRIPTION
The AD7656/AD7657/AD76581 contain six 16-/14-/12-bit,
fast, low power, successive approximation ADCs all in the one
package that is designed on the iCMOS process (industrial
CMOS). iCMOS is a process combining high voltage silicon
with submicron CMOS and complementary bipolar technol-
ogies. It enables the development of a wide range of high
performance analog ICs, capable of 33 V operation in a
footprint that no previous generation of high voltage parts
could achieve. Unlike analog ICs using conventional CMOS
processes, iCMOS components can accept bipolar input signals
while providing increased performance, which dramatically
reduces power consumption and package size.
The AD7656/AD7657/AD7658 feature throughput rates up
to 250 kSPS. The parts contain low noise, wide bandwidth,
track-and-hold amplifiers that can handle input frequencies
up to 12 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 AD7656/AD7657/AD7658 all have
a high speed parallel and serial interface, allowing the devices
to interface with microprocessors or DSPs. In serial interface
mode, the parts have a daisy-chain feature that allows multiple
ADCs to connect to a single serial interface. The AD7656/
AD7657/AD7658 can accommodate true bipolar input signals
in the ±4 × VREF range and ±2 × VREF range. The AD7656/
AD7657/AD7658 also contain an on-chip 2.5 V reference.
PRODUCT HIGHLIGHTS
1. Six 16-/14-/12-bit, 250 kSPS ADCs on board.
2. Six true bipolar, high impedance analog inputs.
3. Parallel and high speed serial interfaces.
