10-bit 300-mA current-source DAC with supervisor comparator or VDAC channel, NVM and GPIO

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 is 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 is

configurable 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 I2C 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 laser diode power control and voice-coil

motor (VCM) control in camera lens auto focus and zoom applications.
