The LTC
®
1446/LTC1446L are dual 12-bit digital-to-analog
converters (DACs) available in an SO-8 package. They are
complete with a rail-to-rail voltage output amplifier, an
internal reference and an easy-to-use 3-wire cascadable
serial interface.
The LTC1446 has an internal reference and a full-scale
output of 4.095V. It operates from a single 4.5V to 5.5V
supply.
The LTC1446L has an internal reference and a full-scale
output of 2.5V. It operates from a single 2.7V to 5.5V
supply.
The low power supply current makes the LTC1446 family
ideal for battery-powered applications. These DACs are
available in space saving 8-pin SO and PDIP packages and
require no external components for operation.
