DESCRIPTION  
FEATURES  
12-Bit Resolution  
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.  
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)  
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.  
CLR Pin  
Power-On Reset  
16-Lead SO Package  
The LTC1454L has an onboard 1.22V reference and a full-  
scale output of 2.5V in a×2 gain configuration. It operates  
from a single 2.7V to 5.5V supply.  
3-Wire Cascadable Serial Interface  
Maximum DNL Error: 0.5LSB  
Low Cost  
U
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.
