3 Description

The DAC104S085 device is a full-featured, generalpurpose

QUAD 10-bit voltage-output digital-to-analog

converter (DAC) that can operate from a single 2.7-V

to 5.5-V supply and consumes 1.1 mW at 3 V and

2.5 mW at 5 V. The DAC104S085 is packaged in 10-

pin SON and VSSOP packages. The 10-pin SON

package makes the DAC104S085 the smallest QUAD

DAC in its class. The on-chip output amplifier allows

rail-to-rail output swing and the three wire serial

interface operates at clock rates up to 40 MHz over

the entire supply voltage range. Competitive devices

are limited to 25-MHz clock rates at supply voltages

in the 2.7-V to 3.6-V range. The serial interface is

compatible with standard SPI, QSPI, MICROWIRE,

and DSP interfaces.

The reference for the DAC104S085 serves all four

channels and can vary in voltage between 1 V and

VA, providing the widest possible output dynamic

range. The DAC104S085 has a 16-bit input shift

register that controls the outputs to be updated, the

mode of operation, the power-down condition, and

the binary input data. All four outputs can be updated

simultaneously or individually depending on the

setting of the two mode of operation bits.
