Product Summary

The REF43GS is a low-power precision reference providing a stable +2.5V output independent of variations in supply voltage, load conditions or ambient temperature. The REF43GS 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.

Parametrics

REF43GS absolute maximum ratings: (1)Supply voltage: 40V; (2)Output short-circuit duration: Indefinite; (3)Operating temperature range: -40℃ to +85℃; (4)Storage temperature range: -65 to +175℃; (5)Junction temperature range: -65 to +175℃; (6)Lead temperature: 300℃.
