ADI AD780BR

Серия, шунтПрограммируемый-40°C ~ 85°C (TA)

Overview

The AD780BR 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 AD780BR 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 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. 

FEATURES Pin programmable 2.5 V or 3.0 V output Ultralow drift: 3 ppm/°C max High accuracy: 2.5 V or 3.0 V ±1 mV max Low noise: 100 nV/√Hz Noise reduction capability Low quiescent current: 1 mA max Output trim capability Plug-in upgrade for present references Temperature output pin Series or shunt mode operation (±2.5 V, ±3.0 V)
