Linear Technology LTC1448

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. The low power supply current and the small SO-8 package make the LTC1448 ideal for battery-powered applications.

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. (For devices with internal reference see the LTC1446 data sheet.) The LTC1448 dissipates 2.5mW from a 5V supply. s s s s SO-8 Package 12-Bit Resolution Buffered True Rail-to-Rail Voltage Output External Reference Input Can Be Tied to VCC Output Swings from 0V to VREF 3V and 5V Supply Operation Schmitt Trigger on Clock Input Allows Direct Optocoupler Interface Power-On Reset Clears DACs to 0V 3-Wire Serial Interface Maximum DNL Error: 0.5LSB Low Cost U
