21 CS 22 WR 24 VSS 01139-001 GENERAL DESCRIPTION The AD7538 is a 14-bit monolithic CMOS digital-to-analog converter (DAC) that uses laser trimmed thin-film resistors to achieve excellent linearity.
The DAC is loaded by a single 14-bit wide word using standard chip select and memory write logic.
Double buffering, which is optional using LDAC, allows simultaneous updates in a s...
