DAC121S101QML

12-Bit Micro Power Digital-to-Analog Converter with Rail-

to-Rail Output

General Description

Features

The DAC121S101 is a full-featured, general purpose 12-bit

voltage-output digital-to-analog converter (DAC) that can op-

erate from a single +2.7 V to 5.5 V supply and consumes just

177 µA of current at 3.6 V. The on-chip output amplifier allows

rail-to-rail output swing and the three wire serial interface op-

erates at clock rates up to 20 MHz over the specified supply

voltage range and is compatible with standard SPI™, QSPI,

MICROWIRE and DSP interfaces.

Total Ionizing Dose

Low Power Operation

Rail-to-Rail Voltage Output

Power-on Reset to Zero Volts Output

SYNC Interrupt Facility

■

The supply voltage for the DAC121S101 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.

Key Specifications

The low power consumption and small packages of the

DAC121S101 make it an excellent choice for use in battery

operated equipment.
