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.
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.
