________________General Description

The MAX4528 low-voltage, CMOS analog IC is config-

ured as a phase-reversal switch and optimized for high-

speed applications such as chopper amplifiers. It

operates from a +2.7V to +12V single supply or from

±2.7V to ±6V dual supplies.

On-resistance (110

Ω max) is matched between switch-

es to 7

analog signals. The leakage current is only 0.5nA at

+25°C and 20nA at +85°C. All digital inputs have 0.8V

to 2.4V logic thresholds, ensuring both TTL- and

CMOS-logic compatibility.

For higher voltage operation, see the MAX4526/

MAX4527 data sheet.
