General Description
The MAX951–MAX954 feature combinations of a
micropower operational amplifier, comparator, and ref-
erence 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 7A,
while the MAX953/MAX954 operate from 2.4V to 7V with
a 5A typical supply current. Both the op amp and
comparator feature a common-mode input voltage
range that extends from the negative supply rail to with-
in 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
10V/V or greater. These op amps have a unique output
stage that enables them to operate with an ultra-low
supply current while maintaining linearity under loaded
conditions. In addition, they have been designed to
exhibit good DC characteristics over their entire operat-
ing temperature range, minimizing input-referred errors.
The comparator output stage of these devices continu-
ously sources as much as 40mA. The comparators
eliminate power-supply glitches that commonly occur
when changing logic states, minimizing parasitic feed-
back and making the devices easier to use. In addition,
they contain ±3mV internal hysteresis to ensure clean
output switching, even with slow-moving input signals.
