Analog Devices Inc./Maxim Integrated MAX4602EAE

Overview

MAX4602EAE from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω maximum on-resistance, 0.5Ω maximum on-resistance match between channels, and 2.5nA maximum off-leakage at +85°C, operating from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies. It is used in automatic test equipment for low-distortion signal switching.

For engineers reviewing the MAX4602EAE datasheet, MAX4602EAE pinout, MAX4602EAE application, or MAX4602EAE equivalent, key selection criteria include guaranteed R_ON flatness (≤0.5Ω), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), ESD protection (>2000V), and −40°C to +85°C industrial temperature rating.

Technical Context

The MAX4602EAE implements four independent CMOS SPST NO switches with matched channel characteristics and rail-to-rail analog signal handling capability. Its control architecture uses standard TTL/CMOS logic inputs referenced to VL, enabling direct interface with microcontrollers or FPGAs without level-shifting when using ±15V or +12V supplies.

All switches share common analog supply rails (V+, V−) and logic supply (VL), with internal protection diodes clamping input signals beyond V+ or V−. The device guarantees monotonic on-resistance behavior over its full analog signal range (±10V with dual supplies, 0–10V with single +12V), critical for audio and instrumentation applications.

FAQ

What is the maximum analog signal voltage range supported by the MAX4602EAE?

The MAX4602EAE supports rail-to-rail analog signals from V− to V+. With dual supplies of ±15V, this yields a ±15V signal range; with single +12V supply (V− = GND), it handles 0V to +12V. Absolute maximum ratings allow V+ to V− differential up to 44V, but specified performance is guaranteed only within ±20V dual or +36V single supply limits.

Does the MAX4602EAE require external level-shifting when interfaced with a 3.3V microcontroller?

No. The MAX4602EAE features TTL/CMOS-compatible logic thresholds (+0.8V low, +2.4V high) and accepts VL = 3.3V or 5V. When VL = 3.3V, a 3.3V microcontroller GPIO directly drives IN1–IN4 without level shifters, provided V+ ≥ +4.5V and V− ≤ 0V (or appropriately biased).

Can the MAX4602EAE be used in a single-supply +5V system?

Yes - the MAX4602EAE operates from +4.5V to +36V single supply. At +5V, R_ON increases slightly (typical 3.5Ω), and signal range is 0V to +5V. Ensure V− is connected to GND, VL = +5V or +3.3V, and analog inputs remain within 0V to +5V to avoid forward-biasing internal protection diodes.

How does the MAX4602EAE's on-resistance matching benefit multiplexer designs?

The MAX4602EAE guarantees ≤0.5Ω R_ON mismatch between any two channels. In a 4:1 multiplexer built from discrete switches, this ensures gain error ≤0.02% across channels when driving identical loads - critical for precision data acquisition where channel-to-channel calibration would otherwise be required.

Is thermal derating required for the MAX4602EAE in a 16-SSOP package at +85°C ambient?

Yes. The 16-SSOP package has a thermal resistance θ_JA of 140°C/W. At maximum rated power dissipation (571mW at +70°C), junction temperature rises significantly above ambient. For continuous operation at +85°C ambient, power must be limited to ≤428mW (derated by 7.1mW/°C above +70°C) to maintain T_J ≤ +125°C.
