LTC1448 Dual 12-Bit Rail-to-Rail Micropower DAC FEATURES s s s s s s s DESCRIPTION The LTC®1448 is a dual rail-to-rail voltage output, 12-bit digital-to-analog converter (DAC).
It includes rail-to-rail output buffer amplifiers and an easy-to-use 3-wire serial interface.
It is available in 8-pin SO and PDIP packages and provides the smallest footprint of any dual 12-bit DAC.
The LTC1448 has an external reference input pin (REF) and its outputs swing from 0V to REF.
The REF input can be tied to VCC providing rail-to-rail operation from supplies of 2.
7V to 5.
5V.
(For devices with internal reference see the LTC1446 data sheet.
