Introduction

The MAX971CSA is a high-performance, low-power, single-supply linear comparator with an on-chip voltage reference. It is designed to operate from a single 2.5V to 11V supply or dual ±1.25V to ±5.5V supplies. The MAX971CSA offers excellent input offset voltage, low input bias current, and high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR).
