GENERAL DESCRIPTION
The ADR225 is a precision 2.5 V band gap voltage reference specified for a high temperature operation of 175°C and 210°C. It uses a micropower core topology and laser trimming of highly stable, thin film resistors to achieve a temperature coefficient of 30 ppm/°C (maximum) up to 175°C and an initial accuracy of 0.4% (±10 m V maximum). A maximum operating current of 50 µA and a low dropout voltage allow the ADR225 to function very well in battery-powered equipment.
