LT6650 Micropower, 400mV Reference with Rail-to-Rail Buffer Amplifier in SOT-23

The LT®6650 is a micropower, low voltage 400mV reference. 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.

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.

The LT6650 is the lowest voltage series reference available in the 5-lead SOT-23 package
