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.
