Product Details

The LTC1458/LTC1458L are complete 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 on-board 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 full-scale output of 2.5V in a ×2 gain configuration. It operates from a single supply of 2.7V to 5.5V dissipating 2.4mW.

Excellent DNL, low supply current and a wide range of built-in functions allow these parts to be used in a host of applications when flexibility, power and single supply operation are important.
