_______________Detailed Desc ription
The MAX951–MAX954 are combinations of a micropow-
er op amp, comparator, and reference in an 8-pin pack-
age, as shown in Figure 1. In the MAX951/MAX952, the
comparator’s negative input is connected to a 1.20V
±2% bandgap reference. All four devices are optimized
to operate from a single supply. Supply current is less
than 10μA (7μA typical) for the MAX951/MAX952 and
less than 8μA (5μA typical) for the MAX953/MAX954.
Op Amp
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
gain bandwidth, 66V/ms slew rate, and stability for
gains of 10V/V or greater. All these op amps feature
high-impedance differential inputs and a common-
mode input voltage range that extends from the nega-
tive supply rail to within 1.6V of the positive rail. They
have a CMOS output stage that swings rail to rail and is
driven by a proprietary high gain stage, which enables
them to operate with an ultra-low supply current while
maintaining linearity under loaded conditions. Careful
design results in good DC characteristics over their
entire operating temperature range, minimizing input
referred errors.
Comparator
The comparator in the MAX951–MAX954 has a high-
impedance differential input stage with a common-
mode input voltage range that extends from the
negative supply rail to within 1.6V of the positive rail.
Their CMOS output stage swings rail to rail and can
