The MAX9060–MAX9064 are extremely small com-
parators ideal for compact, low-current, and low-
voltage applications.
The MAX9060/MAX9061 consume only 50nA (typ) oper-
ating current, while the MAX9062/MAX9063/MAX9064
consume only 400nA (typ). The low-voltage operating
capability of the MAX9060–MAX9064 makes these
devices extremely attractive to long-life battery-operat-
ed devices—these applications can now use a single
digital power-supply rail to power the new generation of
microcontrollers (which can be down to 0.9V). A single
AA/AAA cell can drop down to 0.9V in full discharge. All
parts are available in a tiny 4-bump UCSP, that is only
0.6mm tall, and occupies a 1mm x 1mm footprint and a
5-pin SOT23.
Noninverting inputs are available on the MAX9060/
MAX9062/MAX9064 and inverting inputs are available
on the MAX9061/MAX9063.
The MAX9060–MAX9064 incorporate an innovative
input stage architecture that allows their input voltage
to exceed V

comparators that have an input ESD diode clamp
between the input and V
voltage to about 0.3V. The MAX9060–MAX9064 archi-
tecture maintains a high input impedance to input
signals even when the device power-supply voltage is
completely turned off (V
greatly benefits flexible power-saving schemes to be
easily implemented in advanced battery-operated
devices. On-chip filtering provides immunity from any
RF noise being picked up by input traces. These
devices feature an internal temperature-compensated,
low-power 0.2V reference voltage.
The MAX9060–MAX9063 have open-drain outputs that
allow them to interface to logic circuitry running from
supply voltages other than the one supplied to the part.
These devices require an external pullup resistor or
current source for proper operation. Many microcon-
troller digital inputs ports can be readily programmed to
include these.
The MAX9064 has a push-pull output stage that can
both sink and source current, eliminating the need for
an external pullup resistor. In this case, the MAX9064
uses the microcontroller’s power supply as V

open-drain outputs. The MAX9064 has a push-pull
output.
