Analog Devices Inc./Maxim Integrated MAX4552CPE

Overview

MAX4552CPE from Maxim Integrated is a quad, low-voltage, normally open (NO) single-pole/single-throw (SPST) analog switch IC. It supports rail-to-rail analog signal handling up to ±4.5V with 120Ω typical on-resistance at ±5V supplies, ±15kV IEC 1000-4-2 ESD protection on NO/NC pins, and TTL/CMOS-compatible logic inputs. It is used in audio signal routing and battery-operated test equipment where robust switching and low leakage are critical.

For engineers reviewing the MAX4552CPE datasheet, MAX4552CPE pinout, MAX4552CPE application, or MAX4552CPE equivalent, key selection criteria include its 1nA COM off-leakage at +25°C, 100ns turn-off time at ±5V, 4Ω max on-resistance matching between channels, and compatibility with +2.7V to +12V single or ±2V to ±6V dual supplies.

Technical Context

The MAX4552CPE implements four independent CMOS SPST switches with separate digital control inputs (IN1–IN4), each driving a normally open path between COMx and NOx terminals. Its internal architecture uses complementary N- and P-channel MOSFETs with out-of-phase gate drive referenced to V+ and V−, enabling rail-to-rail signal conduction without distortion.

ESD protection relies on integrated bidirectional SCRs between NO/NC pins and GND-triggering within nanoseconds during ±15kV contact discharge events-plus series-limited diode clamps to V+/V− for non-ESD overvoltage conditions. Holding current is 70mA (positive) / 65mA (negative) at +85°C, requiring external current limiting below 35mA for guaranteed SCR turn-off.

Key Specifications

Pinout & Package

MAX4552CPE is housed in a 16-pin plastic DIP package (0.300" wide) with through-hole mounting. Pin 1 is located at the left end of the top row when viewed from the top with the notch or dot oriented left.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in high-performance analog, mixed-signal, and power management ICs for industrial, communications, and consumer applications.

The MAX455x family was designed specifically for robust, low-leakage analog switching in ESD-sensitive environments such as portable instrumentation and front-panel audio interfaces-prioritizing rail-to-rail operation, ultra-low off-leakage, and integrated protection.

FAQ

What is the maximum allowable supply voltage differential for MAX4552CPE?

The absolute maximum V+ to V− differential voltage for MAX4552CPE is 13.0V. Exceeding this-such as using ±6V supplies with ±10% tolerance (13.2V worst-case)-can cause permanent damage. Designers must ensure combined supply tolerances and transient spikes remain within this limit, especially in dual-supply configurations.

Does MAX4552CPE support single-supply operation below +2.7V?

No. MAX4552CPE is fully specified for single-supply operation from +2.7V to +12V. At +2.5V, parameters like on-resistance (500Ω max) and logic thresholds (V_{IN_H} = 1.1V typ.) degrade significantly. For sub-2.7V systems, consider the MAX4617 or similar low-voltage optimized switches instead of MAX4552CPE.

How does the SCR-based ESD protection in MAX4552CPE affect circuit design?

The integrated SCRs on NO/NC pins require external current limiting to ≤35mA to guarantee turn-off after an ESD event-especially critical at +85°C where holding current drops to 65mA. Sources connected to these pins must include series resistors; COM-side sources do not require limiting. This behavior is intrinsic to MAX4552CPE's protection architecture and must be accounted for in front-end interface design.

Can MAX4552CPE be used with asymmetric dual supplies, e.g., V+ = +5V and V− = -3V?

Yes. MAX4552CPE supports asymmetric dual supplies as long as the V+ to V− differential remains ≤13.0V and each supply stays within its absolute rating (V+ ≤ +13.0V, V− ≥ −13.0V). With V+ = +5V and V− = −3V, the analog signal range becomes −3V to +5V, and on-resistance will reflect the reduced P-channel drive-verified in the datasheet's typical curves.

Is MAX4552CPE pin-compatible with the DG212 analog switch?

Yes. MAX4552CPE is explicitly designed as a pin-compatible upgrade to the industry-standard DG212, sharing identical pinout, logic polarity, and functional block diagram. This allows direct replacement in existing designs without PCB modification-retaining the same footprint, routing, and control timing while adding ±15kV ESD protection and improved leakage performance.
