3 Description
The 8-bit DAC43508, 10-bit DAC53508, and 12-bit
DAC63508 (DACx3508) are low-power, eight-channel,
voltage-output, digital-to-analog converters (DACs).
The DACx3508 are specified monotonic by design
across a wide power supply range from 1.8V to
5.5V. Using an external reference, the DACx3508
provides a full-scale output voltage range of 1.8V to
5.5V while consuming 0.1mA quiescent current per
channel. The DACx3508 also includes per channel,
user programmable, power down registers. These
registers facilitate the DAC output buffers to start in
a 10kΩ-AGND power-down state, and remain in this
state until a power-up command is issued to these
output buffers.
Low quiescent current, wide power-supply range,
octal channel, and a per-channel power-down option
make the DACx3508 an excellent choice for highdensity,
low-power, battery-operated systems.
The devices communicate through the 3-wire (writeonly)
serial peripheral interface (SPI). These devices
also have a load DAC (LDAC) and clear (CLR) inputs.
