FEATURES

DESCRIPTION

The DAC121S101 is a full-featured, general purpose

2

•

Total Ionizing Dose 100 krad(Si)

12-bit

voltage-output

digital-to-analog

converter

•

(DAC) that can operate from a single +2.7 V to 5.5 V

•

Guaranteed Monotonicity

supply and consumes just 177 µA of current at 3.6 V.

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

•

Low Power Operation

swing and the three wire serial interface operates at

•

Rail-to-Rail Voltage Output

clock rates up to 20 MHz over the specified supply

•

Power-on Reset to Zero Volts Output

voltage range and is compatible with standard SPI,

QSPI, MICROWIRE and DSP interfaces.

•

SYNC Interrupt Facility

•

Wide power supply range (+2.7 V to +5.5 V)

The supply voltage for the DAC121S101 serves as its

voltage reference, providing the widest possible

•

Small Packages

output dynamic range. A power-on reset circuit

•

Power Down Feature

ensures that the DAC output powers up to zero volts

and remains there until there is a valid write to the

APPLICATIONS

device.

A

power-down

feature

reduces

power

consumption to less than a microWatt.

•

Battery-Powered Instruments

•

Digital Gain and Offset Adjustment

The low power consumption and small packages of

the DAC121S101 make it an excellent choice for use

•

Programmable Voltage & Current Sources

in battery operated equipment.

•

Programmable Attenuators

The

DAC121S101

operates

over

the

extended

temperature range of -55°C to +125°C.
