Low supply current: 50 µA maximum Initial accuracy: ±0.4% (±10 mV maximum), 8-lead SOIC Low dropout voltage Wide supply range: 3.3 V to 16 V APPLICATIONS Down-hole drilling and instrumentation Avionics Heavy industrial High temperature environments GENERAL DESCRIPTION
The ADR225 is a precision 2.5 V band gap voltage reference It is also available in an 8-lead ceramic flat pack (FLATPACK) specified for a high temperature operation of 175°C and 210°C. with an operating temperature range of −40°C to +210°C. Both It uses a micropower core topology and laser trimming of highly devices are designed for robustness at extreme temperatures stable, thin film resistors to achieve a temperature coefficient of and are qualified for 1000 hours of operation at the maximum 30 ppm/°C (maximum) up to 175°C and an initial accuracy of 0.4% temperature rating. (±10 mV maximum). A maximum operating current of 50 µA The ADR225 is a member of a growing series of high temperature and a low dropout voltage allow the ADR225 to function very qualified products offered by Analog Devices, Inc. For a complete well in battery-powered equipment. selection table of the available high temperature products, see The ADR225 voltage reference is offered in an 8-lead SOIC the high temperature product list and qualification data available package with an operating temperature range of −40°C to +175°C. at www.analog.com/hightemp.
