MAX951MAX954 Ultra-Low-Power, Single-Supply Op Amp + Comparator + Reference General Description Features The MAX951MAX954 feature combinations of a micro- Op Amp + Comparator + Reference in an 8-Pin power operational amplifier, comparator, and reference MAX Package (MAX951/MAX952) in an 8-pin package. In the MAX951 and MAX952, the 7A Typical Supply Current (Op Amp + Comparator + comparators inverting input is connected to an internal Reference) 1.2V 2% bandgap reference. The MAX953 and MAX954 Comparator and Op Amp Input Range Includes are offered without an internal reference. The MAX951/ Ground MAX952 operate from a single 2.7V to 7V supply with a Outputs Swing Rail to Rail typical supply current of 7A, while the MAX953/MAX954 operate from 2.4V to 7V with a 5A typical supply current. 2.4V to 7V Supply Voltage Range Both the op amp and comparator feature a common- Unity-Gain Stable and 125kHz Decompensated mode input voltage range that extends from the negative A 10V/V Op Amp Options V supply rail to within 1.6V of the positive rail, as well as Internal 1.2V 2% Bandgap Reference output stages that swing Rail-to-Rail . Internal Comparator Hysteresis The op amps in the MAX951/MAX953 are internally com- pensated to be unity-gain stable, while the op amps in the Op Amp Capable of Driving up to 1000pF Load MAX952/MAX954 feature 125kHz typical bandwidth, 66V/ ms slew rate, and stability for gains of 10V/V or greater.
