PRECISION SHUNT VOLTAGE

REFERENCE

SC4040

PRELIMINARY - April 13, 1998

FEATURES

The SC4040 is a two terminal precision voltage

reference with thermal stability guaranteed over

temperature. The SC4040 has a typical dynamic

output impedance of 0.25

Ω. Active output circuitry

provides a very sharp turn on characteristic - the

minimum operating current is 60µA, with a maximum

of 20mA.

Available with five voltage tolerances (0.1%, 0.2%,

0.5%, 1.0% and 2.0%) and three package outlines

(SOT-23, SO-8 and TO-92), this part allows the

designer the opportunity to select the optimum

combination of cost and performance for their

application.
