MIC6270 Micrel MIC6270 IttyBitty™ Comparator Final Information General Description Features The MIC6270 is a precision voltage comparator with an offset • 2V to 36V supply voltage specification of 5mV maximum. • 300µA supply current independent of supply • 25nA input bias current The MIC6270 is designed to operate from a single 2V to 36V • ±5nA input offset current power supply. Operation from split power supplies is also • ±3mV input offset voltage possible. Its low supply current drain is independent of the • Input common-mode voltage range includes ground magnitude of the supply voltage. • Differential input voltage range equal to the power This comparator also features an input common-mode volt- supply voltage age range that includes ground. Inputs are protected again
