Product Details

OBSOLETE PRODUCT Data Sheet For Reference Only

The LT580/LT581 are bandgap voltage references utilizing thin film technology and a greatly improved curvature correction technique. Wafer level trimming of both reference and output voltage combines to produce units with high yields to very low TC and tight initial tolerance of output voltage.

The LT580/LT581 can both sink and source up to 10mA and can be used in either the series or shunt mode. This allows the reference to be used for both positive and 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.

For voltage references with improved specifications, please set the LT1019, LT1021, and LT1031 data sheets.
