Analog Devices Inc./Maxim Integrated MAX4522CPE

Overview

MAX4522CPE from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) analog switch with four normally open (NO) configurations, 100Ω max on-resistance at ±5V supplies, 4Ω max channel-to-channel on-resistance matching, and rail-to-rail analog signal handling up to ±6V dual or +12V single supply - used in precision audio routing and battery-powered data acquisition systems.

For engineers reviewing the MAX4522CPE datasheet, MAX4522CPE pinout, MAX4522CPE application, or MAX4522CPE equivalent, key selection considerations include its TTL/CMOS-compatible logic thresholds (+0.8V/2.4V), <1µW quiescent power, 1nA off-leakage at +25°C, and pin compatibility with DG211/DG212/DG213 for drop-in replacement in legacy analog signal path designs.

Technical Context

The MAX4522CPE implements four independent CMOS SPST switches using complementary N- and P-channel MOSFETs driven by level-translated logic inputs, enabling rail-to-rail analog conduction without ground reference. Its internal ESD protection diodes clamp signals exceeding V+ or V−, limiting analog input range to (V− − 0.3V) to (V+ + 0.3V).

It operates across dual supplies (±2V to ±6V) or single supply (+2V to +12V), fully specified down to +2.7V. Logic inputs maintain TTL/CMOS compatibility across all supply configurations, with input thresholds scaling slightly with V+ - e.g., ~3.1V high threshold at V+ = +12V - ensuring robust interfacing with mixed-voltage digital controllers.

Key Specifications

Pinout & Package

MAX4522CPE uses a 16-pin plastic DIP (P16-1) package with 0.300" wide body, through-hole mounting, and industry-standard pin spacing. Pin 1 is top-left corner when notch faces up.

FAQ

What is the maximum supply voltage rating for MAX4522CPE?

The MAX4522CPE has an absolute maximum V+ to V− differential of 13.0V. For dual-supply operation, this limits usable ranges to ±6V (12V total) with margin for tolerance and transients. At ±5V (10V differential), it operates safely within spec; exceeding 13.0V risks permanent damage. Single-supply operation supports up to +12V on V+, with V− tied to GND.

Does MAX4522CPE support rail-to-rail analog signals with a +3.3V single supply?

Yes, MAX4522CPE supports rail-to-rail analog signals from 0V to +3.3V when operated with V+ = +3.3V and V− = GND. Electrical characteristics are fully specified down to +2.7V supply, with 600Ω max on-resistance and guaranteed logic thresholds (0.8V/1.6V) ensuring reliable switching even at low voltage.

How does the pinout of MAX4522CPE differ from MAX4521CPE?

MAX4522CPE uses NO (normally open) switches, so Pins 3, 14, 11, and 6 are NO1–NO4, whereas MAX4521CPE uses NC (normally closed) switches at those same pins. Both share identical COM, IN, V+, V−, GND, and N.C. pin assignments - only the switched terminal type differs, making them functionally distinct but physically pin-compatible for board layout reuse.

Can MAX4522CPE be used in AC-coupled audio paths without DC bias concerns?

Yes, MAX4522CPE requires no DC bias on analog signals - its CMOS switch architecture passes AC signals bidirectionally across the full V− to V+ range. With proper coupling capacitors and termination, it handles audio frequencies up to 50MHz with flat response and <−90dB off-isolation, avoiding DC offset injection or signal clipping.

Is thermal derating required for MAX4522CPE in continuous operation at +70°C ambient?

Yes - the MAX4522CPE plastic DIP package has a derating factor of 10.53mW/°C above +70°C. At TA = +70°C, its continuous power dissipation is rated at 842mW. For sustained operation above +70°C, power must be reduced linearly; e.g., at +85°C, max dissipation drops to 842mW − (15°C × 10.53mW/°C) = 684mW.
