Analog Devices Inc./Maxim Integrated MAX4552EPE

Overview

MAX4552EPE from Maxim Integrated is a quad, low-voltage, normally open (NO) single-pole/single-throw (SPST) analog switch IC designed for rail-to-rail signal routing in battery-powered and precision analog systems. It features ±15kV IEC 1000-4-2 ESD protection on NO/NC pins, 120Ω max on-resistance at ±5V supplies, 4Ω max channel-to-channel R_ON match, and 1nA COM off-leakage at +25°C. It operates from +2V to +12V single supply or ±2V to ±6V dual supplies, supporting audio signal routing and data acquisition front-ends.

For engineers reviewing the MAX4552EPE datasheet, MAX4552EPE pinout, MAX4552EPE application, or MAX4552EPE equivalent, key selection criteria include its NO-only switching configuration, ESD-hardened NC/NO terminals, guaranteed -40°C to +85°C industrial temperature range, 16-pin plastic DIP package, and compatibility with TTL/CMOS logic under +5V supply conditions.

Technical Context

The MAX4552EPE implements four independent SPST switches using complementary N- and P-channel MOSFETs in parallel per channel, driven by level-shifted gate signals derived from V+ and V−. Its internal SCR-based ESD protection activates within nanoseconds during ±15kV contact discharge events on NO pins, clamping surge current to GND while limiting supply injection via series resistors.

Switch operation supports bidirectional analog signal flow between COM and NO terminals, with rail-to-rail voltage handling bounded by V+ and V−. Logic inputs accept 0.8V/2.4V thresholds for TTL/CMOS compatibility, and the device maintains flat on-resistance (≤8Ω over signal range) and tight channel matching (≤4Ω ΔR_ON) across the full operating temperature range.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage rating for MAX4552EPE?

The MAX4552EPE has an absolute maximum V+ to V− differential voltage of 13.0V. When operated with ±5V supplies (±10% tolerance), the worst-case differential is 11.0V - safely within rating. Exceeding 13.0V risks permanent damage, so designs using ±6V supplies must ensure strict regulation to avoid overshoot beyond 13.2V.

Does MAX4552EPE support single-supply operation?

Yes, MAX4552EPE operates from a single +2V to +12V supply with V− connected to GND. In this mode, analog signals swing from 0V to V+, and logic inputs retain TTL/CMOS compatibility. The device is fully specified for +2.7V single-supply operation, delivering 500Ω max R_ON and 200pC max charge injection at that voltage.

How does the ESD protection on MAX4552EPE work during a ±15kV event?

During a ±15kV IEC 1000-4-2 contact discharge on a NO pin, on-chip bidirectional SCRs activate in <5ns, shunting >95% of surge current to GND. Internal series resistors limit current into V+ and V− supplies. The SCR remains latched until current falls below ~70mA (at +85°C); thus, external current limiting below 35mA ensures reliable turn-off after ESD events.

What is the function of Pin 12 (N.C.) on MAX4552EPE?

Pin 12 on MAX4552EPE is a no-connect terminal - it is not bonded to the die and has no internal connection. Leaving it unconnected on the PCB is mandatory; routing traces to or from Pin 12 may cause parasitic coupling or mechanical stress. This pin exists solely for package symmetry and pin-count alignment with other MAX455x variants.

Can MAX4552EPE be used in audio applications requiring low THD?

Yes, MAX4552EPE achieves <0.01% THD at 1kHz with 600Ω source/load and ±5V supplies, verified in Typical Operating Characteristics (Figure MAX4551-11). Its low 120Ω R_ON, flat resistance profile (≤8Ω variation), and rail-to-rail capability minimize harmonic distortion and level-dependent crosstalk in line-level audio routing paths.
