Analog Devices Inc./Maxim Integrated MAX4602CPE

Overview

MAX4602CPE from Maxim Integrated is a quad single-pole single-throw (SPST) CMOS analog switch with four normally open (NO) configurations, 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 - ideal for 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 match (≤0.5Ω), low off-leakage (≤2.5nA at +85°C), TTL/CMOS-compatible logic thresholds, and 16-pin plastic DIP package compatibility with legacy through-hole layouts.

Technical Context

The MAX4602CPE implements four independent SPST NO switches using high-voltage CMOS process technology, enabling operation across wide supply ranges while maintaining flat on-resistance (≤0.5Ω variation over ±10V signal range). Each channel features matched R_ON (≤0.5Ω max difference between channels) and integrated ESD protection (>2000V per Method 3015.7).

Digital control inputs accept TTL/CMOS logic levels (V_{IN_L} ≤ 0.8V, V_{IN_H} ≥ 2.4V) regardless of supply configuration, and all analog terminals (COM/NO) support rail-to-rail voltage swing relative to V+ and V−. The device exhibits 85pF COM off-capacitance and −56dB off-isolation at 1MHz, confirming suitability for audio and medium-frequency signal routing.

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 industry-standard PCB footprints and socketing.

FAQ

What is the operating temperature range for the MAX4602CPE?

The MAX4602CPE is specified for commercial temperature operation from 0°C to +70°C. This range is confirmed in the Ordering Information table and applies specifically to the 'C' grade suffix in the part number. It is not rated for extended industrial (−40°C to +85°C) operation - that variant is designated MAX4602EPE.

Can the MAX4602CPE operate from a single +5V supply?

No, the MAX4602CPE cannot operate reliably from a single +5V supply. Its absolute minimum single-supply voltage is +4.5V, but electrical characteristics (e.g., R_ON, leakage) are only guaranteed down to +12V in the published data. For +5V systems, consider alternatives like the TS5A3157 or ADG1419.

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

Yes, the MAX4602CPE requires a dedicated VL supply pin (Pin 12), typically +5V, to bias internal logic circuitry. VL may be tied to V+ only if V+ ≤ +5.5V; otherwise, VL must be independently regulated to avoid exceeding absolute maximum ratings on logic inputs.

Is the MAX4602CPE pin-compatible with the MAX4601CPE or MAX4603CPE?

Yes, the MAX4602CPE shares identical pinout and package with MAX4601CPE and MAX4603CPE - all are 16-pin DIP devices with same terminal assignments. However, logic behavior differs: MAX4601CPE has NC switches, MAX4602CPE has NO switches, and MAX4603CPE mixes both. Swapping requires firmware or schematic logic inversion.

What is the maximum continuous current rating per switch in the MAX4602CPE?

The MAX4602CPE supports ±200mA continuous current per COM/NO path, as specified in Absolute Maximum Ratings. This rating holds across the full operating temperature range and is independent of supply voltage - critical for driving moderate-power transducers or relay coils in hybrid signal/power applications.
