10-Bit Micro Power, RRO Digital-to-Analog Converter
General Description
The DAC101S101 is a full-featured, general purpose 10-bit
voltage-output digital-to-analog converter (DAC) that can op-
erate 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 inter-
face operates at clock rates up to 30 MHz over the specified
supply voltage range and is compatible with standard SPI ™ ,
QSPI, MICROWIRE and DSP interfaces. Competitive de-
vices 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 voltage
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
DAC101S101 operates over the extended industrial temper-
ature range of −40°C to +105°C while the DAC101S101Q
operates over the Grade 1 automotive temperature range of
−40°C to +125°C. The DAC101S101 is available in a 6-lead
TSOT and an 8-lead MSOP and the DAC101S101Q is avail-
abe in the 6-lead TSOT only.
