LTC1658

14-Bit Rail-to-Rail

Micropower DAC in MSOP

FEATURES

DESCRIPTION

The LTC

1658 is a single supply, rail-to-rail voltage out-

put, 14-bit digital-to-analog converter (DAC) in an 8-lead

MSOP package. It includes an output buffer amplifier and

an easy-to-use 3-wire cascadable serial interface.

The LTC1658 output swings from 0V to V

REF

. The REF pin

can be tied to V

for rail-to-rail output swing. The LTC1658

operates from a single 2.7V to 5.5V supply. The typical

power supply current is 270µA.

The low power supply current makes the LTC1658 ideal

for battery-powered applications. The space saving MSOP

provides the smallest 14-bit DAC system available.
