GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD7676 is a 16-bit, 500 kSPS, charge redistribution SAR,

fully differential analog-to-digital converter that operates 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.

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.

The AD7676 is hardware factory calibrated and is comprehensively

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.

3. Fast Throughput

The AD7676 is a 500 kSPS, charge redistribution, 16-bit

SAR ADC with internal error correction circuitry.

4. Single-Supply Operation

It is fabricated using Analog Devices’ high-performance, 0.6

micron CMOS process and is available in a 48-lead LQFP with

operation specified from –40°C to +85°C.

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 or 16 bits) or 2-wire serial interface

arrangement compatible with either 3 V or 5 V logic.
