•

Guaranteed Monotonicity

8-bit voltage-output digital-to-analog converter (DAC)

•

Low Power Operation

that can operate from a single +2.7V to 5.5V supply

•

Rail-to-Rail Voltage Output

and consumes just 175 µA of current at 3.6 Volts.

The on-chip output amplifier allows rail-to-rail output

•

Power-on Reset to Zero Volts Output

swing and the three wire serial interface operates at

•

SYNC Interrupt Facility

clock rates up to 30 MHz over the specified supply

•

Wide Power Supply Range (+2.7V to +5.5V)

voltage range and is compatible with standard SPI™,

QSPI, MICROWIRE and DSP interfaces. Competitive

•

Small Packages

devices are limited to 20 MHz clock rates at supply

•

Power Down Feature

voltages in the 2.7V to 3.6V range.

The supply voltage for the DAC081S101 serves as its

voltage reference, providing the widest possible

•

Battery-Powered Instruments

output dynamic range. A power-on reset circuit

•

Digital Gain and Offset Adjustment

ensures that the DAC output powers up to zero volts

and remains there until there is a valid write to the

•

Programmable Voltage & Current Sources

device.

A

power-down

feature

reduces

power

•

Programmable Attenuators

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.
