Product Summary
The LT1019ACN8-2.5 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 LT1019ACN8-2.5 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. The LT1019ACN8-2.5 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. The application of the LT1019ACN8-2.5 are Negative Shunt References, A/D and D/A Converters, Precision Regulators, Constant Current Sources, V/F Converters, Bridge Excitation.
