Description

General part information

LT1019 Series

The LT1019 is a third generation bandgap voltage reference utilizing thin film technology and a greatly improved curvature correction technique. Wafer level trimming of both reference and output voltage combines to produce very low TC and tight initial output voltage tolerance.The LT1019 can both sink and source up to 10mA and can be used in either the series or shunt mode, allowing the reference to operate with positive or negative output voltages without external components. Minimum input/ output voltage is less than 1V in the series mode, providing improved tolerance of low line conditions and excellent line regulation.The LT1019 is available in four voltages: 2.5V, 4.5V, 5V and 10V. It is a direct replacement for most bandgap references presently available including AD580, AD581, REF-01, REF-02, MC1400, MC1404 and LM168.ApplicationsNegative Shunt ReferencesA/D and D/A ConvertersPrecision RegulatorsConstant Current SourcesV/F ConvertersBridge Excitation
