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 open-drain outputs permit wire-ORed configurations. Thanks to an 11V output range and separate GND pin for the output transistor (MAX971/MAX974, MAX981/MAX984), these devices are ideal for level translators and bipolar to single-ended converters. For similar devices with complementary output stages, see the MAX921-MAX924 (1% reference) and the MAX931–MAX934 (2% reference).
