They include an output buffer amplifier and an easy-to-use 3-wire cascadable serial interface. It operates from a single 4.5V to 5.5V supply. 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.
