Overview
19-0450; Rev 3; 2/03 Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators General Description The MAX971–MAX974 and MAX981–MAX984 single/ dual/quad low-voltage comparators feature the lowest power consumption available.
These micropower devices draw less than 4µA supply current over temperature (MAX971/MAX972/MAX981/MAX982), and include an internal 1.
182V ±1% (MAX971/MAX973/ MAX974) or ±2% (MAX981–MAX984) voltage reference and programmable hysteresis.
Ideal for 3V or 5V single-supply applications, these devices operate from a single 2.
5V to 11V supply (or ±1.
25V to ±5.
5V dual supplies), and each comparator’s input voltage ranges from the negative supply rail to within 1.
3V of the positive supply.
The single MAX971/MAX981 and the dual MAX973/ MAX982/MAX983 provide a unique, simple method for adding hysteresis without feedback or complicated equations, simply by using the HYST pin plus two resistors.
The MAX971–MAX974 and MAX981–MAX984’s opendrain outputs permit wire-ORed configu...
