LTC7543/LTC8143

Improved Industry Standard

Serial 12-Bit Multiplying DACs

FEATURES

DESCRIPTION

The LTC^®7543/LTC8143 are serial-input 12-bit multiply-

ingdigital-to-analogconverters(DACs).Theyaresuperior

pin compatible replacements for the AD7543 and

DAC-8143. Improvements include better accuracy, better

stability over temperature and supply variations, lower

sensitivity to output amplifier offset, tighter timing speci-

fications and lower output capacitance.

■

Improved Direct Replacement for AD7543

and DAC-8143

Low Cost

DNL and INL Over Temperature: ±0.5LSB

Easy, Fast and Flexible Serial Interface

■

Daisy-Chain 3-Wire Interface for Multiple DAC

Systems (LTC8143)

■

1LSB Maximum Gain Error Over Temperature

An easy-to-use serial interface includes an asynchronous

CLEARinputforsystemsrequiringinitializationtoaknown

state. The LTC8143 has a serial data output to allow daisy-

chaining multiple DACs on a 3-wire interface bus.

Eliminates Adjustment

■

Asynchronous Clear Input for Initialization

■

Four-Quadrant Multiplication

Low Power Consumption

16-Pin PDIP and SO Packages

■

These DACs are extremely versatile. They can be used for

2-quadrant and 4-quadrant multiplying, programmable

gain and single supply applications, such as noninverting

voltage output and biased or offset ground mode.

APPLICATIONS

■

Process Control and Industrial Automation

Remote Microprocessor-Controlled Systems

Digitally Controlled Filters and Power Supplies

Programmable Gain Amplifiers

Automatic Test Equipment

Parts are available in 16-pin PDIP and SO packages and

are specified over the extended industrial temperature

range, –40°C to 85°C.
