The LTC
1454/LTC1454L are complete single supply,
dual rail-to-rail voltage output, 12-bit digital-to-analog
converters (DACs) in a 16-lead SO package. They include
an output buffer amplifier with variable gain (
×
1 or
×
2)
and an easy-to-use 3-wire cascadable serial interface.
The LTC1454 has an onboard reference of 2.048V and a
full-scale output of 4.095V in a
×
2 gain configuration. It
operates from a single 4.5V to 5.5V supply.
The LTC1454L has an onboard 1.22V reference and a full-
scale output of 2.5V in a
×
2 gain configuration. It operates
from a single 2.7V to 5.5V supply.
Low power supply current, excellent DNL and small size
allow these parts to be used in a host of applications where
size, DNL and single supply operation are important.
