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
CC
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.
