PRODUCTION DATA
The 10-bit DAC53508 and 8-bit DAC43508 (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 1.8 V to 5.5 V. Using an external reference, the DACx3508 provides a full-scale output voltage range of 1.8 V to 5.5 V while consuming 0.1‑mA 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 10 kΩ-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) SPI interface. These devices also have a load DAC (LDAC) and clear CLR inputs.
