DESCRIPTION
The LTC®7543/LTC8143 are serial-input 12-bit multiplying digital-to-analog converters (DACs). They are superior 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 specifications and lower output capacitance.

FEATURES
■ 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 Eliminates Adjustment
■ Asynchronous Clear Input for Initialization
■ Four-Quadrant Multiplication
■ Low Power Consumption
■ 16-Pin PDIP and SO Packages

APPLICATIONS
■ Process Control and Industrial Automation
■ Remote Microprocessor-Controlled Systems
■ Digitally Controlled Filters and Power Supplies
■ Programmable Gain Amplifiers
■ Automatic Test Equipment
