3 Description

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
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.
