Description

General part information

LTC1454 Series

The LTC1454/LTC1454L are complete single supply, dual rail-to-rail voltage output, 12-bit digital-to-analog converters (DACs) in a 16-lead SO package. They include an output buffer amplifier with variable gain (×1 or ×2) and an easy-to-use 3-wire cascadable serial interface.The LTC1454 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.The LTC1454L has an on board 1.22V reference and a full-scale output of 2.5V in a ×2 gain configuration. It operates from a single 2.7V to 5.5V supply.Low power supply current, excellent DNL and small size allow these parts to be used in a host of applications where size, DNL and single supply operation are important.ApplicationsDigital CalibrationIndustrial Process ControlAutomatic Test EquipmentCellular Telephones
