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 fullscale 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 ponents provide the smallest 12-bit DAC system available. , LTC and LT are registered trademarks of Linear Technology Corporation.
