GENERAL DESCRIPTION
The AD7654 is a low cost, simultaneous sampling, dual-
channel, 16-bit, charge redistribution SAR, analog-to-digital
converter that operates from a single 5 V power supply. It
contains two low noise, wide bandwidth, track-and-hold
amplifiers that allow simultaneous sampling, a high speed
16-bit sampling ADC, an internal conversion clock, error
correction circuits, and both serial and parallel system interface
ports. Each track-and-hold has a multiplexer in front to provide
a 4-channel input ADC. The A0 multiplexer control input
allows the choice of simultaneously sampling input pairs
INA1/INB1 (A0 = low) or INA2/INB2 (A0 = high). The part
features a very high sampling rate mode (normal) and, for low
power applications, a reduced power mode (impulse) where the
power is scaled with the throughput. Operation is specified
from 40°C to +85°C.
PRODUCT HIGHLIGHTS
1.
Simultaneous Sampling.
The AD7654 features two sample-and-hold circuits that
allow simultaneous sampling. It provides inputs for four
channels.
2.
Fast Throughput.
The AD7654 is a 500 kSPS, charge redistribution, 16-bit
SAR ADC with internal error correction circuitry.
3.
Superior INL and No Missing Codes.
The AD7654 has a maximum integral nonlinearity of
3.5 LSB with no missing 16-bit codes.
4.
Single-Supply Operation.
The AD7654 operates from a single 5 V supply. In impulse
mode, its power dissipation decreases with throughput.
5.
Serial or Parallel Interface.
Versatile parallel or 2-wire serial interface arrangement is
compatible with both 3 V and 5 V logic.
