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 VREF. The REF pin
can be tied to VCC forrail-to-railoutputswing.TheLTC1658
operates from a single 2.7V to 5.5V supply. The typical
power supply current is 270
A.
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.
