The LTC
1451/LTC1452/LTC1453 are complete single
supply, rail-to-rail voltage output 12-bit digital-to-analog
converters (DACs) in an SO-8 package. They include an
output buffer amplifier and an easy-to-use 3-wire
cascadable serial interface.
The LTC1451 has an onboard reference of 2.048V and a
full-scale output of 4.095V. It operates from a single 4.5V
to 5.5V supply.
The LTC1452 is a multiplying DAC with a full-scale output
of twice the reference input voltage. It operates from a
single supply of 2.7V to 5.5V.
The LTC1453 has an onboard 1.22V reference and a full-
scale output of 2.5V. It operates from a single supply of
2.7V to 5.5V.
The low power supply current makes the LTC1451 family
ideal for battery-powered applications. The space saving
8-pin SO package and operation with no external compo-
nents provide the smallest 12-bit DAC system available.
