Overview
The WEA05114BG45G is a high precision band gap reference voltage that provides a 500 mV and a 1.14 V output from inputs between 1.8 V and 3.0 V. It is a Bipolar style Bandgap based on SOI Forward Biased Diodes. The SOI Diodes are not tied to the substrate, in this way the circuit simultaneously provides PTAT, CTAT and is constant with temperature currents. It is specified over the −40°C to +120°C temperature range.
