GENERAL DESCRIPTION
The AD7654 is a low cost, 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 con-
version 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 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. It is available in
48-lead LQFP or 48-lead LFCSP packages with operation
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 4-channel inputs.
2. Fast Throughput
The AD7654 is a very high speed (500 kSPS in Normal
Mode and 444 kSPS in Impulse Mode), charge redistribution,
16-bit SAR ADC that avoids pipeline delay.
3. Superior INL and No Missing Code
The AD7654 has a maximum integral nonlinearity of 3.5 LSB
with no missing codes at the 16-bit level.
4. Single-Supply Operation
The AD7654 operates from a single 5 V supply and dissipates
only 120 mW typical, even lower when a reduced throughput
is used with the reduced power mode (Impulse) and power-
down mode.
5. Serial or Parallel Interface
Versatile parallel or 2-wire serial interface arrangement is
compatible with both 3 V or 5 V logic.
