Quiescent current maxes at 4 µA, so in a battery-powered threshold detector (over-temperature flag, undervoltage lockout, window comparator) the comparator itself is not the dominant drain. ## Supply and signal conditions Input offset voltage is 10 mV max at 5 V, and the built-in 50 mV hysteresis prevents output chatter when the input signal sits near the threshold — no external positive-feedback resistors needed. CMRR and PSRR are both 80 dB typical, so the threshold accuracy holds up when the supply rail droops or the common-mode voltage shifts — relevant in a noisy automotive or industrial 12 V environment.","metaTitle":"MAX971ESA+ Comparator with Voltage Reference, 8-SOIC","metaDescription":"Active production MAX971ESA+ comparator with integrated voltage reference. 4µA quiescent current, open-drain output, 80dB CMRR. 8-SOIC package.
