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.

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

selection table of the available high temperature products, see

the high temperature product list and qualification data available at

www.analog.com/hightemp.

The ADR225 voltage reference is offered in an 8-lead SOIC

package with an operating temperature range of −40°C to +175°C.
