DAC084S085

8-Bit Micro Power QUAD Digital-to-Analog Converter with

Rail-to-Rail Output

General Description

Features

The DAC084S085 is a full-featured, general purpose QUAD

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

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

1.1 mW at 3V and 2.5 mW at 5V. The DAC084S085 is pack-

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

package makes the DAC084S085 the smallest QUAD DAC

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

put 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 DAC084S085 serves all four channels

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

widest possible output dynamic range. The DAC084S085 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. All four outputs can be updated simul-

taneously 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.

The low power consumption and small packages of the

DAC084S085 make it an excellent choice for use in battery

operated equipment.

The DAC084S085 is one of a family of pin compatible DACs,

including the 10-bit DAC104S085 and the 12-bit

DAC124S085. The DAC084S085 operates over the extended

industrial temperature range of −40°C to +105°C.
