3 Description

The DAC53608 and DAC43608 (DACx3608) are lowpower,

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.
