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.
