LTC8043

Serial 12-Bit Multiplying

DAC in SO-8

FEATURES

DESCRIPTION

The LTC^®8043 is a serial-input 12-bit multiplying digital-

to-analog converter (DAC). It is a superior pin compatible

replacement for the DAC-8043. Improvements include

better accuracy, better stability over temperature and

supply variations, lower sensitivity to output amplifier

offset, tighter timing specifications and lower output ca-

pacitance.

■

Improved Direct Replacement for DAC-8043 and

MAX543

SO-8 Package

DNL and INL Over Temperature: ±0.5LSB

■

Easy, Fast and Flexible Serial Interface

1LSB Maximum Gain Error

4-Quadrant Multiplication

Low Power Consumption

Low Cost

An easy-to-use 3-wire serial interface is well-suited to

remote or isolated applications

The LTC8043 is extremely versatile. It can be used for

2-quadrant and 4-quadrant multiplying, programmable

gain and single supply applications, such as noninverting

voltage output mode.

APPLICATIONS

■

Process Control and Industrial Automation
