Product Summary

The REF43G is a low-power precision reference. The REF43G can provide a stable +2.5V output independent of variations in supply voltage. load conditions or ambient temperature. The REF43G is suitable as a reference level for 8, 10 and 12-bit data acquisition systems, or whereever 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 characterisitc of many previous bandgap references.

Parametrics

REF43G absolute maximum ratings: (1)supply voltage: 40V; (2)output short-circuit duration: indefinite; (3)operating temperature range: -55 to 125℃; (4)storage temperature range: -65 to 175℃; (5)junction temperature range: -65 to 175℃; (6)lead temperature (soldering, 10 sec): 300℃.

Features

REF43G features: (1)+2.5Volt output: ±0.05% max; (2)low temperature coefficient: 10ppm/℃ max; (3)excellent regulation: load regulation: 20ppm/mA max; line regulation: 2ppm/V max; (4)supply current: 450μA max; (5)temperature voltage output: 1.9mV/℃; (6)operating voltage range: +4.5V to +40V; (7)extended industrial temp range: -40 to 85℃; (8)available in die form.
