SC4040
2.5V Precision Shunt
Voltage Reference
Description
.eatures
Revision 2, May 2001
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
. Active output circuitry provides a
very sharp turn on characteristic - the minimum
operating current is 80A, 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-23-3,
SO-8 and TO-92), this part allows the designer the
opportunity to select the optimum combination of cost
and performance for their application.
