GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
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.  
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.
