MAX6061AEUR-T

Overview

The MAX6061AEUR-T is a precision, micropower voltage reference featuring a fixed output of 1.248V. It operates within an input voltage range of 2.5V to 12.6V and delivers up to 5mA sourcing current with 2mA sinking capability. The device exhibits an initial accuracy of ±0.32% and a maximum temperature coefficient of 20ppm/°C. Quiescent supply current is typically 90µA, extending to 125µA maximum. Noise performance is specified at 13µVp-p from 0.1Hz to 10Hz. It functions reliably across an extended temperature range of -40°C to +85°C.
