GENERAL DESCRIPTION  
The AD7676 is a 16-bit, 500 kSPS, charge redistribution SAR,  
fully differential analog-to-digital converter (ADC) that oper-  
ates from a single 5 V power supply. The part contains a high  
speed 16-bit sampling ADC, an internal conversion clock,  
error correction circuits, and both serial and parallel system  
interface ports.  
PRODUCT HIGHLIGHTS  
1. Excellent INL  
The AD7676 has a maximum integral nonlinearity of 1.0 LSB  
with no missing 16-bit code.  
The AD7676 is hardware factory-calibrated and is comprehen-  
sively tested to ensure such ac parameters as signal-to-noise ratio  
(SNR) and total harmonic distortion (THD), in addition to the  
more traditional dc parameters of gain, offset, and linearity.  
2. Superior AC Performances  
The AD7676 has a minimum dynamic of 92 dB, 94 dB typical.  
3. Fast Throughput  
The AD7676 is a 500 kSPS, charge redistribution, 16-bit  
It is fabricated using Analog Devices’ high performance, 0.6 micron  
CMOS process and is available in a 48-lead LQFP or a tiny  
48-lead LFCSP with operation specified from –40°C to +85°C.  
SAR ADC with internal error correction circuitry.  
4. Single-Supply Operation  
The AD7676 operates from a single 5 V supply and typically  
dissipates only 67 mW. It consumes 7 µW maximum when in  
power-down.  
5. Serial or Parallel Interface  
Versatile parallel (8 bits or 16 bits) or 2-wire serial interface  
arrangement compatible with either 3 V or 5 V logic.
