MAX951

MAX951–MAX954 Ultra-Low-Power, Single-Supply Op Amp + Comparator + Reference 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 commonmode 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®. The op amps in the MAX951/MAX953 are internally compensated to be unity-gain stable, while the op amps in the MAX952/MAX954 feature 125kHz typical bandwidth, 66V/ ms slew rate, and stability for gains of...
