Part Number: MAX971
Function: Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparator
Package: DIP 8 Pin Type
Manufacturer: Maxim Integrated
The MAX971 Thru MAX974 and MAX981 Thru 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 thru 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.
