PRODUCT HIGHLIGHTS

1. Fast, 12-Bit ADC in 8-Pin Package

GENERAL DESCRIPTION

The AD7893 is a fast, 12-bit ADC that operates from a single

+5 V supply and is housed in a small 8-pin mini-DIP and 8-pin

SOIC. The part contains a 6 µs successive approximation A/D

converter, an on-chip track/hold amplifier, an on-chip clock and

a high speed serial interface.

The AD7893 contains a 6 µs ADC, a track/hold amplifier,

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

package. This offers considerable space saving over alterna-

tive solutions.

2. Low Power, Single Supply Operation

Output data from the AD7893 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.

The AD7893 operates from a single +5 V supply and con-

sumes only 25 mW. This low power, single supply operation

makes it ideal for battery powered or portable applications.

3. High Speed Serial Interface

In addition to traditional dc accuracy specifications such as lin-

earity, full-scale and offset errors, the AD7893 is also specified

for dynamic performance parameters, including harmonic dis-

tortion and signal-to-noise ratio.

The part provides high speed serial data and serial clock lines,

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

The part accepts an analog input range of ±10 V (AD7893-10),

±2.5 V (AD7893-3), 0 V to +5 V (AD7893-5) or 0 V to +2.5 V

(AD7893-2) and operates from a single +5 V supply, consuming

only 25 mW typical.

The AD7893 is fabricated in Analog Devices’ Linear Compat-

ible CMOS (LC²MOS) process, a mixed technology process

that combines precision bipolar circuits with low power CMOS

logic. The part is available in a small, 8-pin, 0.3" wide, plastic or

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

outline IC (SOIC).
