Manufacturer Part Number
sc4040ez
Description
Precision Shunt Voltage Reference
Manufacturer
Semtech Corporation
Datasheet
PRELIMINARY - April 13, 1998
DESCRIPTION
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
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.
