Texas Instruments DACx3508 Octal Buffered Voltage Output Digital-to-Analog Converter (DAC) are 10-bit (DAC53508) and 8-bit (DAC43508) low-power, eight-channel, voltage-output, DACs. The DACx3508 are 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 excellent for high-density, low-power, battery-operated systems. The Texas Instruments DACx3508 devices communicate through the 3-wire (write-only) SPI interface. These devices also have a load DAC (LDAC) and clear CLR inputs.
