DAC104S085
10-Bit Micro Power QUAD Digital-to-Analog Converter with
Rail-to-Rail Output
General Description
The DAC104S085 is a full-featured, general purpose QUAD
10-bit voltage-output digital-to-analog converter (DAC) that
can operate from a single +2.7V to 5.5V supply and consumes
1.1 mW at 3V and 2.5 mW at 5V. The DAC104S085 is pack-
aged in 10-lead LLP and MSOP packages. The 10-lead LLP
package makes the DAC104S085 the smallest QUAD DAC
in its class. The on-chip output amplifier allows rail-to-rail out-
put 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 sup-
ply voltages in the 2.7V to 3.6V 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 1V and V
widest possible output dynamic range. The DAC104S085 has
a 16-bit input shift register that controls the outputs to be up-
dated, the mode of operation, the powerdown condition, and
the binary input data. All four outputs can be updated simul-
taneously or individually depending on the setting of the two
mode of operation bits.
A power-on reset circuit ensures that the DAC output powers
up to zero volts and remains there until there is a valid write
to the device. A power-down feature reduces power con-
sumption to less than a microWatt with three different termi-
nation options.
The low power consumption and small packages of the
DAC104S085 make it an excellent choice for use in battery
operated equipment.
The DAC104S085 is one of a family of pin compatible DACs,
including the 8-bit DAC084S085 and the 12-bit DAC124S085.
The DAC104S085 operates over the extended industrial tem-
perature range of −40°C to +105°C.
