ANALOG DEVICES REF43: 2.5 V Low Power Precision Voltage Reference Data Sheet (Rev D 2004-08-01-) handbook
The REF43 is a low power precision voltage reference designed to provide a stable 2.5 V output. It is suitable for use as a reference level in 8-, 10-, and 12-bit data acquisition systems or any application requiring a stable, known voltage. The device ensures tight output tolerances and low thermal drift through zener-zap trimming of both the output voltage and its temperature coefficient. Additionally, a unique curvature correction circuit is included to reduce thermal curvature, a characteristic often found in traditional bandgap references.
