MAX872ESA

Overview

The MAX872ESA is a precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.48%. The device operates within an input voltage range of 2.7V to 20V and draws a supply current of 15µA. It features a temperature coefficient of 40ppm/°C and exhibits low noise characteristics of 60µVp-p in the 0.1Hz to 10Hz band. The component functions reliably across a junction temperature range of -40°C to +85°C.
