Ultra-Small, Low-Power, Window Comparator
in 4 UCSP and 5 SOT23
MAX9065
General Description
Features
The MAX9065 is an ultra-small, low-power, window com-
parator ideal for a wide variety of portable electronics
applications such as cell phones, portable media play-
ers, 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.
o Tiny 1mm x 1mm 4-Bump UCSP
Footprint = Two 0402 Resistors
Also Available in 5-Pin SOT23 Package
o Ultra-Low Power Operating Current
1µA (max)
o -0.3V to +5.5V Input Voltage Range
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 pow-

o -40°C to +85°C Extended Temperature Range
tures 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 tem-
perature range.
