LTC7545A

Improved Industry Standard

Parallel 12-Bit Multiplying DAC

FEATURES

DESCRIPTIO

Improved Direct Replacement for AD7545A

and AD7545

DNL and INL Over Temperature:

±0.5LSB

Gain Error:

±1LSB

Maximum

4-Quadrant Multiplication

Single 5V or 15V Supply

Low Power Consumption

Low Cost

The LTC

7545A is a 12-bit multiplying digital-to-analog

converter (DAC) with a microprocessor compatible paral-

lel input. It is a superior pin compatible replacement for the

industry standard AD7545A and AD7545. Improvements

include better accuracy, better stability over temperature

and supply variations and lower sensitivity to output

amplifier offset.

This very versatile DAC is useful for 2-quadrant and

4-quadrant multiplying, programmable gain and filtering

and single supply noninverting voltage output operation.

Parts are available in 20-pin PDIP and SO packages and

commercial and industrial temperature grades.
