LT6650

Micropower, 400mV

Reference with Rail-to-Rail

Buffer Amplifier in SOT-23

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.

■

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
