Product Overview

The AD780 series ultrahigh precision band-gap Voltage Reference provides a 2.5 or 3V output from inputs between 4V and 36V. 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 analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) and for any general-purpose precision reference application. A unique low headroom design facilitates a 3V output from a 5V 10% input, providing a 20% boost to the dynamic range of an ADC over performance with existing 2.5V references. The AD780 can be used to source or sink up to 10mA and can be used in series or shunt mode, thus allowing positive or negative output voltages without external components. This makes it suitable for virtually any high performance reference application. Unlike some competing references, the AD780 has no region of possible instability.
