REF43
+2.5 V Low Power Precision
Voltage Reference
FEATURES
PIN CONFIGURATION
GENERAL DESCRIPTION
The REF43 is a low power precision reference providing a
stable 2.5 V output independent of variations in supply voltage,
load conditions or ambient temperature. It is suitable as a
reference level for 8-, 10- and 12-bit data acquisition systems,
or wherever a stable, known voltage is required.

Tight output tolerances and low thermal drift are assured by
zener-zap trimming of both output voltage and its temperature
coefficient. A unique curvature correction circuit reduces the
thermal curvature which is characteristic of many previous
bandgap references.
