REF43 Datasheet PDF | Analog Devices

Analog Devices REF43

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. Although the REF43 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges.

FEATURES

+2.5 V Low Power Precision Voltage Reference REF43 PIN CONFIGURATION

GENERAL DESCRIPTION

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.
