Texas Instruments DACx3608 Low-Power Digital-to-Analog Converters
Texas Instruments DACx3608 Low-Power Digital-to-Analog Converters (DACs) are eight-channel, voltage-output, 10-bit, or 8-bit digital-to-analog converters (DACs), respectively. The DACx3608 are specified monotonic by design across a wide power supply range from 1.8V to 5.5V. Using an external reference, the DACx3608 provides a full-scale output voltage range of 1.8V to 5.5V while consuming 0.1mA quiescent current per channel. The DACx3608 also includes per channel, user programmable, and power-down registers. These registers facilitate the DAC output buffers to start in a power-down to 10K state and remain in this state until a power-up command is issued to these output buffers.Low quiescent current, wide power supply range and per-channel power-down options make the DACx3608 ideal for low-power, battery-operated systems. These devices communicate through the I2C interface. The Texas Instruments DACx3608 support I2C standard mode (100kbps), fast mode (400kbps), and fast+ mode (1Mbps). These devices also have a load DAC (LDAC) pin that allows simultaneous DAC updates.
