TheLTC®1446/LTC1446Laredual12-bitdigital-to-analog  
converters (DACs) available in an SO-8 package. They are  
complete with a rail-to-rail voltage output amplifier, an  
internal reference and an easy-to-use 3-wire cascadable  
serial interface.

3V Operation (LTC1446L): ICC = 650µA Typ  
5V Operation (LTC1446): ICC = 1000µA Typ  
Internal Reference  
Power-On Reset Clears DACs to 0V  
3-Wire Cascadable Serial Interface  
Maximum DNL Error: 0.5LSB  
Low Cost  
Schmitt Trigger On Input Allows Direct  
Optocoupler Interface  
The LTC1446 has an internal reference and a full-scale  
output of 4.095V. It operates from a single 4.5V to 5.5V  
supply.  
The LTC1446L has an internal reference and a full-scale  
output of 2.5V. It operates from a single 2.7V to 5.5V  
supply.  
The low power supply current makes the LTC1446 family  
ideal for battery-powered applications. These DACs are  
available in space saving 8-pin SO and PDIP packages and  
require no external components for operation.
