The MAX965–MAX970 single/dual/quad micropower
comparators feature rail-to-rail inputs and outputs, and
fully specified single-supply operation down to +1.6V.
These devices draw less than 5µA per comparator and
have open-drain outputs that can be pulled beyond V
to 6V (max) above ground. In addition, their rail-to-rail
input common-mode voltage range makes these com-
parators suitable for ultra-low-voltage operation.
A +1.6V to +5.5V single-supply operating voltage range
makes the MAX965 family of comparators ideal for 2-cell
battery-powered applications. The MAX965/MAX967/
MAX968/MAX969 offer programmable hysteresis and
an internal 1.235V ±1.5% reference. All devices are
available in either space-saving 8-pin µMAX
QSOP packages.

Ultra-Low-Voltage, Rail-to-Rail I/O Comparators function below about 1.5V, although the comparators typically continue to operate with a supply voltage as low as 1V. At low supply voltages (<1.6V), the input common-mode range remains rail-to-rail, but the com- parator’s output sink ...

... This is apparent only when programming addi- tional hysteresis using the HYST pin. The hysteresis band is constant when HYST is connected to REF. The MAX966/MAX970 do not have a HYST pin for pro- gramming hysteresis. Hysteresis can be generated with three resistors using positive feedback (Figure 4). This ...
