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 high-density, low-power, battery-operated systems.

The devices communicate through the 3-wire (write-only) serial peripheral interface (SPI). These devices also have a load DAC (LDAC) and clear (CLR) inputs.
