Phase-Reversal Analog Switches

The MAX4526/MAX4527 are CMOS analog ICs configured as phase-reversal switches. The MAX4526 is optimized for high-speed applications, such as chopper 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-resistance (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.
