LTC1454L

LTC1454/LTC1454L Dual 12-Bit Rail-to-Rail Micropower DACs FEATURES s s s s s DESCRIPTION The LTC®1454/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 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. The LTC1454L has an onboard 1.22V reference and a fullscale 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. s s s s s s U APPLICATIONS s s s s 12-Bit Resolution Buffered True Rail-to-Rail Voltage Output 5V Operation, ICC: 700µA Typ (LTC1454) 3V Operation, ICC: 450µA Typ (LTC1454L) Built-In Reference: 2.048V (LTC1454) 1.220V (LTC1454L) CLR Pin Power-On Reset 16-Lead SO Package 3-Wire Cascadable Serial Interface Maximum DNL Error: 0.5LSB Low Cost Digital Calibration Industrial Process Control Automatic Test Equipment Cellular Telephones , LTC and LT are registered trademarks of Linear Technology Corporation.
