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.
