GENERAL DESCRIPTION

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 AD7671 is a 16-bit, 1 MSPS, 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

conversion clock, error correction circuits, and both serial

and parallel system interface ports.

PRODUCT HIGHLIGHTS

1. Fast Throughput

The AD7671 is a very high speed (1 MSPS in Warp Mode

and 800 kSPS in Normal Mode), charge redistribution, 16-bit

SAR ADC.

The AD7671 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. Single-Supply Operation

The AD7671 operates from a single 5 V supply, dissipates

only 112 mW typical, even lower when a reduced throughput

is used with the reduced power mode (Impulse) and a power-

down mode.

It features a very high sampling rate mode (Warp), a fast mode

(Normal) for asynchronous conversion rate applications, and, for

low power applications, a reduced power mode (Impulse) where

the power is scaled with the throughput.

3. Superior INL

The AD7671 has a maximum integral nonlinearity of 2.5 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.
