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.
The MAX4526 and MAX4527 are CMOS analog ICs configured as phase‑reversal switches. They are optimized for high‑speed (MAX4526) or low‑power (MAX4527) applications such as chopper amplifiers, balanced modulators, and data‑acquisition circuits. The devices operate from a wide supply range and provide rail‑to‑rail signal handling with TTL/CMOS‑compatible inputs.
Key electrical characteristics include a supply range of +4.5 V to +36 V (single) or ±4.5 V to ±18 V (dual), on‑resistance up to 175 Ω (matched to 8 Ω between switches), leakage currents as low as 0.5 nA at 25 °C, transition times under 100 ns with ±15 V supplies, and >2 kV ESD protection. The ICs are offered in 8‑pin DIP, SO and µMAX packages.
