Product Summary
The AD7538KRZ is a 14-bit monolithic CMOS D/A converter which 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 update in a system containing multiple AD7538s. The applications of the AD7538KRZ include Microprocessor Based Control Systems, Digital Audio, Precision Servo Control, Control and Measurement in High Temperature, Environments.
