DAC43608 - 8-bit, I2C interface, buffered-voltage-output digital-to-analog converter (DAC)

The DAC53608 and DAC43608 (DACx3608) are low-power, eight-channel, voltage-output, 10-bitor 8-bit digital-to-analog converters (DACs) respectively. The DACx3608 are specified monotonic bydesign across a wide power supply range from 1.8 V to 5.5 V. Using an external reference, theDACx3608 provides a full scale output voltage range of 1.8 V to 5.5 V while consuming 0.1-mAquiescent current per channel. The DACx3608 also includes per channel, user programmable, powerdown registers. These registers facilitate the DAC output buffers to start in a power down to 10Kstate 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 option makesDACx3608 ideal for low power, battery operated systems.

The devices communicate through theI²C^TM interface. These devices supportI²C^TM standard mode (100 kbps), fast mode(400 kbps), and fast+ mode (1 Mbps). These devices also have a load DAC(LDAC) pin that allows simultaneous DAC updates.

The DACx3608 are available in small 3-mm × 3-mm, 16-pin WQFN package. The devices arefully specified over the extended industrial temperature range of –40°C to +125°C.
