GENERAL DESCRIPTION  
Simultaneous/  
Multichannel  
AD7654  
AD7655  
The AD7660 is a 16-bit, 100 kSPS, charge redistribution SAR,  
analog-to-digital converter that operates from a single 5 V power  
supply. The part contains an internal conversion clock, error cor-  
rection circuits, and both serial and parallel system interface ports.  
PRODUCT HIGHLIGHTS  
1. Fast Throughput  
The AD7660 is a 100 kSPS, charge redistribution, 16-bit  
SAR ADC with internal error correction circuitry.  
2. Superior INL  
The AD7660 has a maximum integral nonlinearity of 3 LSBs  
with no missing 16-bit code.  
3. Single-Supply Operation  
The AD7660 operates from a single 5 V supply and only  
dissipates 21 mW typical. Its power dissipation decreases  
with the throughput to, for instance, only 21 mW at a 100 SPS  
throughput. It consumes 7 mW maximum when in power-down.  
4. Serial or Parallel Interface  
The AD7660 is hardware factory-calibrated and is comprehen-  
sively tested to ensure ac parameters such as signal-to-noise ratio  
(SNR) and total harmonic distortion (THD), in addition to the  
more traditional dc parameters of gain, offset, and linearity.  
It is fabricated using Analog Devices’ high performance,  
0.6 micron CMOS process with correspondingly low cost and is  
available in a 48-lead LQFP and a tiny 48-lead LFCSP with  
operation specified from –40C to +85C.  
Versatile parallel or 2-wire serial interface arrangement com-  
patible with both 3 V or 5 V logic.
