Product Details
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 selection table of the available high temperature products, see the high temperature product list and qualification data available at www.analog.com/hightemp.
