MAX6034BEXR21

Overview

The MAX6034BEXR21+T is a precision micropower low-dropout series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2.5 V to 5.5 V and draws a supply current of 115 µA. It features a maximum output current of 1 mA and a temperature coefficient of 30 ppm/°C. Noise performance is specified at 45 µVp-p (0.1 Hz to 10 Hz) and 46 µVrms (10 Hz to 10 Hz). The component functions in a temperature range of -40°C to +85°C and is housed in a SC-70-3 surface-mount package.
