The LTC
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.
