GENERAL DESCRIPTION

The AD7663 is a 16-bit, 250 kSPS, charge redistribution SAR,

analog-to-digital converter that operates from a single 5 V power

supply. It contains a high speed 16-bit sampling ADC, a resistor

input scaler that allows various input ranges, an internal conver-

sion clock, error correction circuits, and both serial and parallel

system interface ports.

PRODUCT HIGHLIGHTS

1. Fast Throughput

The AD7663 is a 250 kSPS charge redistribution, 16-bit

SAR ADC with various bipolar and unipolar input ranges.

2. Single-Supply Operation

The AD7663 operates from a single 5 V supply and dissipates

only 35 mW typical. Its power dissipation decreases with

the throughput to, for instance, only 15 µW at a 100 SPS

throughput.

The AD7663 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 consumes 7 µW maximum when in power-down.

3. Superior INL

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

CMOS process and is available in a 48-lead LQFP and a tiny

48-lead LFCSP with operation specified from –40°C to +85°C.

The AD7663 has a maximum integral nonlinearity of 3 LSB

with no missing 16-bit code.

4. Serial or Parallel Interface

Versatile parallel (8 bits or 16 bits) or 2-wire serial interface

arrangement compatible with both 3 V or 5 V logic.
