DAC101S101
10-Bit Micro Power Digital-to-Analog Converter with
Rail-to-Rail Output
General Description
The DAC101S101 is a full-featured, general purpose 10-bit
voltage-output digital-to-analog converter (DAC) that can
operate from a single +2.7V to 5.5V supply and consumes
just 175 µA of current at 3.6 Volts. The on-chip output
amplifier allows rail-to-rail output swing and the three wire
serial interface operates at clock rates up to 30 MHz over the
specified supply voltage range and is compatible with stan-
dard SPI, QSPI, MICROWIRE and DSP interfaces. Com-
petitive devices are limited to 20 MHz clock rates at supply
voltages in the 2.7V to 3.6V range.
The supply voltage for the DAC101S101 serves as its volt-
age reference, providing the widest possible output dynamic
range. 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 consumption to less than a microWatt.
The low power consumption and small packages of the
DAC101S101 make it an excellent choice for use in battery
operated equipment.
The DAC101S101 is a direct replacement for the AD5310
and is one of a family of pin compatible DACs, including the
8-bit DAC081S101 and the 12-bit DAC121S101. The
DAC101S101 operates over the extended industrial tem-
perature range of −40˚C to +105˚C.
