Analog Devices Inc./Maxim Integrated MAX4602CPE+

Overview

MAX4602CPE+ from Maxim Integrated is a quad, single-pole single-throw (SPST), normally open (NO) CMOS analog switch with 2.5Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail analog signal handling up to ±10V. It delivers matched on-resistance (≤0.5Ω max between channels), flat on-resistance (≤0.5Ω max over signal range), and 2.5nA max off-leakage at +85°C - ideal for precision reed relay replacement in automated test equipment.

For engineers reviewing the MAX4602CPE+ datasheet, MAX4602CPE+ pinout, MAX4602CPE+ application, or MAX4602CPE+ equivalent, key selection criteria include guaranteed R_ON matching across all four switches, TTL/CMOS-compatible logic thresholds (+0.8V low / +2.4V high), 16-pin plastic DIP package compatibility, and verified performance in audio-signal routing and PBX system switching under industrial temperature conditions (0°C to +70°C).

Technical Context

The MAX4602CPE+ implements four independent SPST NO switches using high-voltage CMOS process technology, enabling true rail-to-rail analog conduction from V− to V+ without signal clipping. Each switch features symmetrical on-resistance characteristics across its full analog input range (±10V), with tight channel-to-channel matching ensured by matched transistor layout and process trimming.

Control logic operates independently per channel via dedicated INx pins referenced to VL (logic supply), supporting interoperability with both TTL and CMOS drivers regardless of analog supply configuration. Internal ESD protection exceeds 2000V per Method 3015.7, and all analog terminals (COM/NO) tolerate overvoltage clamping to V+ and V− rails via integrated diodes.

Key Specifications

Pinout & Package

MAX4602CPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and standard through-hole mounting. Pin spacing is 0.1 inch, compatible with legacy PCB layouts and socket-based prototyping.

Manufacturer

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

The MAX460x family was designed specifically for high-reliability, low-distortion analog switching in mission-critical systems where mechanical relay limitations-such as contact wear, slow speed, and size-must be overcome with solid-state alternatives.

FAQ

What is the operating temperature range for MAX4602CPE+?

The MAX4602CPE+ is specified for commercial-grade operation from 0°C to +70°C. This temperature range is validated across all electrical parameters including on-resistance, leakage current, and switching times. The "C" suffix in MAX4602CPE+ explicitly denotes this 0°C to +70°C rating, distinguishing it from the extended −40°C to +85°C "E" grade variants like MAX4602EPE+. All thermal performance data in the datasheet's Typical Operating Characteristics section apply to the MAX4602CPE+ under these conditions.

Can MAX4602CPE+ operate from a single +12V supply?

Yes, MAX4602CPE+ supports single-supply operation from +4.5V to +36V. When using +12V, connect V− to GND, tie VL to +5V (or +3V to +5V), and ensure logic inputs meet the +0.8V low / +2.4V high thresholds. Electrical characteristics such as 2.5Ω R_ON max and 2.5nA off-leakage are fully guaranteed under +12V single-supply conditions per the datasheet's "Single +12V Supply" table. No external level shifting is required for TTL/CMOS control signals.

Does MAX4602CPE+ require a separate logic supply (VL)?

Yes, MAX4602CPE+ requires a dedicated VL supply (3V to 5V) to establish precise logic thresholds independent of analog supplies. This allows TTL/CMOS-compatible operation even when V+ and V− are at ±15V - a key differentiator from simpler analog switches. Connecting VL to the same rail as V+ or GND will cause incorrect switching behavior or damage. The VL pin must be decoupled with a 0.1µF capacitor to GND near the package, as specified in the Applications Information section.

How does MAX4602CPE+ handle overvoltage on analog pins?

MAX4602CPE+ includes internal ESD diodes from each COM and NO pin to V+ and V−, clamping overvoltage transients within absolute maximum ratings (−0.3V to V+ +0.3V). However, sustained overvoltage beyond V+ or below V− risks permanent damage. The datasheet recommends sequencing V+ first, then V−, then logic inputs - or adding external series diodes (D1/D2 in Figure 1) for robust overvoltage protection in uncontrolled environments. These diodes reduce usable analog range by ~0.7V but preserve R_ON and leakage specs.

Is MAX4602CPE+ pin-compatible with other MAX460x variants?

Yes, MAX4602CPE+ shares identical pinout and footprint with all MAX4601/MAX4602/MAX4603 variants in the 16-pin plastic DIP package (e.g., MAX4601CPE+, MAX4603CPE+). The only functional difference is switch configuration: MAX4602CPE+ has four NO switches, while MAX4601CPE+ has four NC and MAX4603CPE+ has two NC + two NO. This allows direct substitution in hardware when logic polarity and switch state behavior are accounted for in firmware or external logic.
