GENERAL DESCRIPTION
The AD7656-1/AD7657-1/AD7658-11 are reduced decoupling pin-
and software-compatible versions of AD7656/AD7657/AD7658.
The AD7656-1/AD7657-1/AD7658-1 devices contain six 16-/
14-/12-bit, fast, low power successive approximation ADCs in
a package designed on the iCMOS process (industrial CMOS).
iCMOS is a process combining high voltage silicon with submicron
CMOS and complementary bipolar technologies. 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 conven-
tional CMOS processes, iCMOS components can accept bipolar
input signals while providing increased performance, which
dramatically reduces power consumption and package size.
The AD7656-1/AD7657-1/AD7658-1 feature throughput rates
of up to 250 kSPS. The parts contain low noise, wide bandwidth
track-and-hold amplifiers that can handle input frequencies
up to 4.5 MHz.
The conversion process and data acquisition are controlled
using the CONVST signals and an internal oscillator. Three
CONVST pins (CONVST A, CONVST B, and CONVST C)
allow independent, simultaneous sampling of the three ADC
pairs. The AD7656-1/AD7657-1/AD7658-1 have a high speed
parallel and serial interface, allowing the devices to interface with
microprocessors or DSPs. When the serial interface is selected,
each part has a daisy-chain feature that allows multiple ADCs to
connect to a single serial interface. The AD7656-1/AD7657-1/
AD7658-1 can accommodate true bipolar input signals in the
±4 × VREF and ±2 × VREF ranges. Each AD7656-1/AD7657-1/
AD7658-1 also contains 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. High speed parallel and serial interfaces.
4. Reduced decoupling requirements and reduced bill of
materials cost compared with the AD7656/AD7657/
AD7658 devices.
