DESCRIPTIO  
FEATURES  
The LT®6650 is a micropower, low voltage 400mV refer-  
ence. Operating with supplies from 1.4V up to 18V, the  
device draws only 5.6µA typical, making it ideal for low  
voltage systems as well as handheld instruments and  
industrial control systems. With only two resistors the  
internal buffer amplifier can scale the 400mV reference to  
any desired value up to the supply voltage.  
Low Quiescent Current 5.6

A (typical)  
Wide Supply Range: 1.4V to 18V  
400mV Reference ±1% Maximum Accuracy Over  
Temperature at 5V  
Rail-to-Rail Buffer Amplifier  
0.5% 400mV Maximum Initial Accuracy at 5V  
Shunt Configurable  
Sinks and Sources Current  
The reference is postpackage-trimmed to increase the  
output accuracy. The output can sink and source 200µA  
over temperature. Quiescent power dissipation is 28µW.  
Stability is ensured with any output capacitor of 1µF or  
higher.  
Wide Operational Range –40°C to 125°C
