3 Description
The DAC104S085 device is a full-featured, general-
purpose 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.
