Low-Voltage, Phase-Reversal Analog Switch

The MAX4528 low-voltage, CMOS analog IC is configured 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 (110Ω max) is matched between switches to 7Ω (max). Each switch can handle rail-to-rail 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.
