MAXIM MAX9065 Technical data

General Description

The MAX9065 is an ultra-small, low-power, window com­parator ideal for a wide variety of portable electronics
applications such as cell phones, portable media play­ers, and notebooks that have extremely tight board
space and power constraints. It comes in both a 4-bump
UCSP™ package with a 1mm x 1mm footprint (as small
as two 0402 resistors) and a 5-pin SOT23 package.

The MAX9065 features a common-mode input range of

-0.3V to +5.5V independent of supply voltage. The
input current goes to zero when the MAX9065 is pow­ered down (VCC= 0). Additionally, the MAX9065 fea­tures high RF immunity.

The MAX9065 has a push-pull output and consumes
only 1µA (max) supply current. The MAX9065 operates
down to 1.0V over the extended -40°C to +85°C tem­perature range.

ELECTRICAL CHARACTERISTICS

(VCC= 3.3V, TA= -40°C to +85°C. Typical values are at TA= +25°C, unless otherwise noted.) (Note 1)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
