DESCRIPTION
The DAC081S101 is a full-featured, general purpose
8-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 standard SPI™,
QSPI, MICROWIRE and DSP interfaces. Competitive
devices are limited to 20 MHz clock rates at supply
voltages in the 2.7V to 3.6V range.
The supply voltage for the DAC081S101 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 DAC081S101 make it an excellent choice for use
in battery operated equipment.
The DAC081S101 is a direct replacement for the
AD5300 and is one of a family of pin compatible
DACs, including the 10-bit DAC101S101 and the 12-
bit DAC121S101. The DAC081S101 operates over
the extended industrial temperature range of −40°C
to +105°C.
