DESCRIPTION
The LTC®1458/LTC1458L are plete single supply, quad rail-to-rail voltage output, 12-bit digital-to-analog converters (DACs) in SO-28 and SSOP-28 packages. They include an output buffer amplifier with variable gain (× 1 or × 2) and an easy-to-use 3-wire cascadable serial interface. The LTC1458 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 dissipating only 5.5mW (ICC = 1.1mA typ). The LTC1458L has an onboard 1.22V reference and a fullscale output of 2.5V in a × 2 gain configuration. It operates from a...
