GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD7896 is a fast, 12-bit ADC that operates from a single

2.7 V to 5.5 V supply and is housed in small 8-lead PDIP and

8-lead SOIC packages. The part contains an 8 µs successive

approximation ADC, an on-chip track-and-hold amplifier, an

on-chip clock, and a high speed serial interface.

1. Complete, 12-bit ADC in an 8-Lead Package.

The AD7896 contains an 8 µs ADC, a track-and-hold ampli-

fier, control logic, and a high speed serial interface, all in an

8-lead PDIP. The V_DDinput is used as the reference for the

part, so no external reference is needed. This offers consider-

able space saving over alternative solutions.

Output data from the AD7896 is provided via a high speed,

serial interface port. This 2-wire serial interface has a serial

clock input and a serial data output with the external serial

clock accessing the serial data from the part.

2. Low Power, Single-Supply Operation.

The AD7896 operates from a single 2.7 V to 5.5 V supply

and consumes only 9 mW typical. The automatic power-

down mode, where the part goes into power down once

conversion is complete and “wakes up” before the next con-

version cycle, makes the AD7896 ideal for battery-powered

or portable applications.

In addition to the traditional dc accuracy specifications, such as

linearity, full-scale, and offset errors, the AD7896 is also speci-

fied for dynamic performance parameters, including harmonic

distortion and signal-to-noise ratio.

3. High Speed Serial Interface.

The part accepts an analog input range of 0 V to V_DDand operates

from a single 2.7 V to 5.5 V supply, consuming only 9 mW

typical. The V_DDinput is also used as the reference for the part

so that no external reference is required.

The part provides high speed serial data and serial clock lines

allowing for an easy, 2-wire serial interface arrangement.

The AD7896 features a high sampling rate mode and, for low

power applications, a proprietary automatic power-down mode

where the part automatically goes into power-down once conver-

sion is complete and “wakes up” before the next conversion cycle.

The part is available in a small, 8-lead, 0.3'' wide, plastic or

hermetic dual-in-line package (PDIP) and in an 8-lead, small

outline IC (SOIC).
