GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

1. Complete, 12-bit ADC in 8-Pin Package

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

+2.7 V to 5.5 V supply and is housed in a small 8-pin mini-DIP

and 8-pin SOIC. The part contains an 8 µs successive approxi-

mation A/D converter, an on-chip track/hold amplifier, an on-

chip clock and a high speed serial interface.

The AD7896 contains an 8 µs ADC, a track/hold amplifier,

control logic and a high speed serial interface, all in an 8-pin

DIP. The V_DDinput is used as the reference for the part so

no external reference is needed. This offers considerable

space saving over alternative solutions.

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

serial interface port. This two-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 con-

version is complete and “wakes up” before the next conver-

sion 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 oper-

ates 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, two-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 con-

version is complete and “wakes up” before the next conversion

cycle.

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

metic dual-in-line package (mini-DIP) and in an 8-pin, small

outline IC (SOIC).
