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 mV maximum). A maximum operating current of
50 µA and a low dropout voltage allow the ADR225 to function
very well in battery-powered equipment.
The ADR225 voltage reference is offered in an 8-lead SOIC
package with an operating temperature range of −40°C to +175°C.

It is also available in an 8-lead ceramic flat pack (FLATPACK)
with an operating temperature range of −40°C to +210°C. Both
devices are designed for robustness at extreme temperatures
and are qualified for 1000 hours of operation at the maximum
temperature rating.
The ADR225 is a member of a growing series of high temperature
qualified products offered by Analog Devices, Inc. For a complete
