The three-channel DAC532A3W and the dual-channel DAC530A2W ( DAC53xAxW) are 10-bit, buffered voltage-output and current-output smart digital-to-analog-converters (DAC). The DAC53xAxW devices support a current source that can be used for linear control of laser diodes and miniature motors. These devices support Hi-Z power-down mode and Hi-Z output during power-off conditions for voltage output. Channel 1 can be configured as a voltage-output DAC or a comparator. The voltage-output DACs provide a force-sense option for use as a programmable comparator and current sink. The multifunction GPIO, function generation, and programmable nonvolatile memory (NVM) enable these smart DACs for processor-less applications and design reuse. These devices automatically detect SPI or I 2C interfaces and contain an internal reference.

The DAC53xAxW feature set combined with the tiny package and low power make these smart DACs an excellent choice for applications such as laser diode power control and voice-coil motor (VCM) control in camera lens auto focus and zoom applications.
