General Description
The MAX951–MAX954 feature combinations of a micropower operational amplifier, comparator, and reference in an 8-pin package. In the MAX951 and MAX952, the comparator’s inverting input is connected to an internal 1.2V ±2% bandgap reference. The MAX953 and MAX954 are offered without an internal reference.
The MAX951/MAX952 operate from a single 2.7V to 7V supply with a typical supply current of 7μA, while the MAX953/MAX954 operate from 2.4V to 7V with a 5μA typical supply current. Both the op amp and comparator feature a common mode input voltage range that extends from the negative supply rail to within 1.6V of the positive rail, as well as output stages that swing Rail-to-Rail®.
