The LTC®1257 is a complete single supply, 12-bit voltage  
output D/A converter (DAC) in an SO-8 package. The  
LTC1257 includes an output buffer amplifier, 2.048V  
voltagereferenceandaneasytousethree-wirecascadable  
serial interface. An external reference can be used to  
override the internal reference and extend the output  
voltage range to 12V. The power supply current is a low  
350µA when operating from a 5V supply, making the  
LTC1257idealforbattery-poweredapplications.Thespace-  
saving 8-pin SO package and operation with no external  
components provide the smallest 12-bit D/A system  
available.  
8-Pin SO Package  
Buffered Voltage Output  
Built-In 2.048V Reference  
500µV/LSB with 2.048V Full Scale  
1/2LSB Max DNL Error  
Guaranteed 12-Bit Monotonic  
3-Wire Cascadable Serial Interface  
Wide Single Supply Range: VCC = 4.75V to 15.75V
