DAC122S085

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

Rail-to-Rail Output

General Description

Features

The DAC122S085 is a full-featured, general purpose DUAL

12-bit voltage-output digital-to-analog converter (DAC) that

can operate from a single +2.7V to 5.5V supply and consumes

0.6 mW at 3V and 1.6 mW at 5V. The DAC122S085 is pack-

aged in 10-lead LLP and MSOP packages. The 10-lead LLP

package makes the DAC122S085 the smallest DUAL DAC in

its class. The on-chip output amplifier allows rail-to-rail output

swing and the three wire serial interface operates at clock

rates up to 40 MHz over the entire supply voltage range.

Competitive devices are limited to 25 MHz clock rates at sup-

ply voltages in the 2.7V to 3.6V range. The serial interface is

compatible with standard SPI™, QSPI, MICROWIRE and

DSP interfaces.

The reference for the DAC122S085 serves all four channels

and can vary in voltage between 1V and V_A, providing the

widest possible output dynamic range. The DAC122S085 has

a 16-bit input shift register that controls the outputs to be up-

dated, the mode of operation, the powerdown condition, and

the binary input data. Both outputs can be updated simulta-

neously or individually depending on the setting of the two

mode of operation bits.

—

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 con-

sumption to less than a microWatt with three different termi-

nation options.

Applications

Battery-Powered Instruments

■

Digital Gain and Offset Adjustment

Programmable Voltage & Current Sources

Programmable Attenuators

The low power consumption and small packages of the

DAC122S085 make it an excellent choice for use in battery

operated equipment.

The DAC122S085 is one of a family of pin compatible DACs,

including the 8-bit DAC082S085 and the 10-bit DAC102S085.

The DAC122S085 operates over the extended industrial tem-

perature range of −40°C to +105°C.
