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.
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.
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.
PRODUCT HIGHLIGHTS
1. Excellent INL
The AD7676 has a maximum integral nonlinearity of 1.0 LSB
with no missing 16-bit code.
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
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
W 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.
