X60003BIG3-50

Overview

The X60003BIG3-50 is a precision voltage reference utilizing Intersil’s proprietary Floating Gate Analog (FGA) technology, offering superior performance over conventional band gap or buried zener designs. It provides an initial accuracy of ±1.0mV (B grade) and features ultra-low power supply current of 500nA. The device exhibits a low temperature coefficient of 10ppm/°C (B grade) and supports 10mA source and sink current capability with a very low dropout voltage of 100mV at no load. Input voltage ranges are 4.5V to 9.0V for the -41 variant and 5.1V to 9.0V for the -50 variant. It includes 5kV ESD protection (human body model) and operates within a temperature range of -40°C to +85°C in a standard 3-lead SOT-23 package.
