REF43S中文资料Aerospace +2.5V Low-Power Precision Voltage Reference数据手册ADI规格书

描述 Description

The REF43 is a low-power precision reference providing a stable +2.5V 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.

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.
