Analog Devices Inc./Maxim Integrated MAX4602EPE

Overview

MAX4602EPE from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with four normally open (NO) channels, rail-to-rail signal handling, 2.5Ω maximum on-resistance, and operation from +4.5V to +36V single supply or ±4.5V to ±20V dual supply. It delivers matched on-resistance (≤0.5Ω between channels), flat on-resistance (≤0.5Ω over signal range), and <2.5nA off-leakage at +85°C - ideal for precision reed-relay replacement in automated test equipment.

For engineers reviewing the MAX4602EPE datasheet, MAX4602EPE pinout, MAX4602EPE application, or MAX4602EPE equivalent, key selection criteria include guaranteed R_ON matching across all four switches, TTL/CMOS-compatible logic thresholds (+0.8V low / +2.4V high), ESD protection >2000V, and 16-pin plastic DIP packaging rated for -40°C to +85°C industrial operation.

Technical Context

The MAX4602EPE implements CMOS-based SPST switching architecture with independent digital control inputs (IN1–IN4) driving four NO switches. Each channel features bidirectional rail-to-rail analog conduction and operates with identical logic thresholds regardless of supply configuration (single or dual).

Its internal charge-pump-free design ensures stable R_ON flatness ≤0.5Ω over ±10V signal swing and maintains ≤0.5Ω match between any two channels - critical for multi-channel signal routing where gain or timing skew must be minimized.

FAQ

What is the operating temperature range for the MAX4602EPE?

The MAX4602EPE is specified for operation from -40°C to +85°C, validated across its full electrical performance envelope including on-resistance, leakage, and switching times. This industrial temperature grade makes it suitable for deployment in harsh environments such as factory automation controllers and airborne electronics where thermal cycling is routine. The MAX4602EPE's 16-pin plastic DIP package maintains mechanical stability across this range without derating.

Does the MAX4602EPE support single-supply operation?

Yes, the MAX4602EPE supports single-supply operation from +4.5V to +36V. In this mode, V− is connected to GND, V+ supplies the positive rail, and VL accepts 2.7V to 5.5V for logic-level referencing. Its TTL/CMOS-compatible inputs (+0.8V low / +2.4V high) function correctly with +12V or +24V single supplies - eliminating level shifters in programmable logic controller (PLC) I/O modules and industrial sensor interfaces.

How does the MAX4602EPE achieve rail-to-rail signal handling?

The MAX4602EPE achieves rail-to-rail analog conduction through a fully complementary CMOS switch architecture that extends conduction to within ~100mV of V+ and V−. Unlike older switch families limited by threshold voltage drops, its design ensures minimal signal clipping across the full analog range - verified by test data showing ≤0.5Ω R_ON flatness over ±10V input swings. This capability is essential for preserving fidelity in audio routing and high-resolution data acquisition.

Can the MAX4602EPE replace mechanical relays directly on existing PCBs?

Yes, the MAX4602EPE in 16-pin plastic DIP format provides direct mechanical and electrical compatibility with legacy relay driver footprints used in ATE fixtures and industrial control panels. Its 0.3-inch DIP width, 0.1-inch pin pitch, and through-hole mounting allow retrofitting without board redesign. Power dissipation remains below 842mW at +70°C ambient, and its solid-state operation eliminates contact bounce, arcing, and finite lifetime concerns inherent to electromechanical relays.

What is the significance of the VL pin on the MAX4602EPE?

The VL pin on the MAX4602EPE supplies the logic interface independently from the analog rails (V+ and V−), allowing logic thresholds to remain stable even when analog supplies vary widely. It accepts 2.7V to 5.5V and sets the +0.8V / +2.4V input thresholds regardless of whether the device runs on ±15V dual supply or +24V single supply. This decoupling prevents false triggering in noisy industrial environments and simplifies interface design with mixed-voltage systems such as FPGA-based controllers with 3.3V I/O banks.
