PRODUCT DESCRIPTION

The AD780 is an ultrahigh precision band gap reference voltage that provides a 2.5 V or 3.0 V output from inputs between 4.0 V and 36 V. Low initial error and temperature drift combined with low output noise and the ability to drive any value of capacitance make the AD780 the ideal choice for enhancing the performance of high resolution ADCs and DACs, and for any general-purpose precision reference application. A unique low headroom design facilitates a 3.0 V output from a 5.0 V 10 input, providing a 20 boost to the dynamic range of an ADC over performance with existing 2.5 V references.
