MAX4527CPA

P1-P3P4-P6P7-P9P10-P12
_______________General Description
The MAX4526/MAX4527 are CMOS analog ICs config-
ured as phase-reversal switches. The MAX4526 is
optimized for high-speed applications, such as chop-
per amplifiers, while the MAX4527 is optimized for
low-power applications.
The MAX4526/MAX4527 operate from a +4.5V to +36V
single supply or ±4.5V to ±18V dual supplies. On-resis-
tance (175Ω max) is matched between switches to 8Ω
maximum. Each switch can handle rail-to-rail analog
signals. Maximum leakage current is only 0.5nA at
+25°C and 10nA at +85°C.
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility.

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.
