LT1019CS8-4.5#TRPBF

Voltage Reference Overview

The LT1019CS8-4.5#TRPBF is a precision shunt voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 4.5V. It operates within an input voltage range of 6.5V to 40V and draws a supply current of 1.5mA. The device offers high accuracy with an initial tolerance of ±0.2% and a temperature coefficient of 20ppm/°C. Noise performance is specified at 2.5ppm peak-to-peak (0.1Hz to 10Hz) and 2.5ppm RMS (10Hz to 1kHz). It supports a maximum cathode current of 800µA and a maximum output current of 10mA, operating reliably from 0°C to +70°C in an 8-SOIC package.
