Description

The DAC53608 and DAC43608 (DACx3608) are low-power, 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 1.8 V to 5.5 V. Using an external reference, the DACx3608 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 DACx3608 also includes per channel, user programmable, 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 option makes DACx3608 ideal for low power, battery operated systems.

The devices communicate through the I2CTM interface. These devices support I2CTM 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 are fully specified over the extended industrial temperature range of –40°C to +125°C.
