Datasheet REF43 (Analog Devices)

+2.5 V Low Power Precision Voltage Reference REF43 FEATURES PIN CONFIGURATION GENERAL DESCRIPTION
Tight output tolerances and low thermal drift are assured by The REF43 is a low power precision reference providing a zener-zap trimming of both output voltage and its temperature stable 2.5 V output independent of variations in supply voltage, coefficient. A unique curvature correction circuit reduces the load conditions or ambient temperature. It is suitable as a thermal curvature which is characteristic of many previous reference level for 8-, 10- and 12-bit data acquisition systems, bandgap references. or wherever a stable, known voltage is required.
