Product details
Overview
MAX20336AEFT+ from Maxim Integrated is a double-pole/single-throw (DPST) analog switch with Beyond-the-Rails™ capability, enabling distortion-free signal switching from −5.5V to +5.5V independent of supply voltage. It features 0.19Ω typical on-resistance, 1.6V–5.5V single-supply operation, −40°C to +85°C temperature range, and 6-pin FC2QFN (1.25mm × 1.75mm) package - optimized for portable audio routing in space-constrained mobile devices.
For engineers reviewing the MAX20336AEFT+ datasheet, MAX20336AEFT+ pinout, MAX20336AEFT+ application, or MAX20336AEFT+ equivalent, this page delivers verified electrical specs, validated pin functions, confirmed thermal and ESD performance, and real-world use cases in smartphone audio subsystems and USB-C accessory detection circuits.
Technical Context
The MAX20336AEFT+ implements a dual-channel DPST topology with fully independent COM1/NO1 and COM2/NO2 paths, each supporting bidirectional analog signal flow. Its charge-pump–assisted architecture enables Beyond-the-Rails operation without external negative supplies, maintaining <0.01Ω on-resistance flatness across the full −5.5V to +5.5V signal range at 2.5V VCCEN.
Control is supply-enabled only: the device activates when VCCEN is ≥1.6V and enters high-impedance state when VCCEN = 0V, allowing safe hot-swap operation. All analog terminals (COM_, NO_) withstand ±5.5V regardless of power state, and digital control requires only standard GPIO-compatible logic thresholds (VIH = 1.4V, VIL = 0.4V).

FAQ
What is the maximum analog signal voltage the MAX20336AEFT+ can handle without distortion?
The MAX20336AEFT+ supports analog signals from −5.5V to +5.5V independent of VCCEN voltage - a feature called Beyond-the-Rails™ operation. This means even when powered from a low 1.6V supply, the device passes full-range audio or video signals without clipping or harmonic distortion, as confirmed by −114dB THD+N measurements at 1VRMS.
Does the MAX20336AEFT+ require an external negative supply to handle signals below ground?
No, the MAX20336AEFT+ does not require an external negative supply. Its internal architecture enables true Beyond-the-Rails™ operation, allowing signals as low as −5.5V to pass through COM1/NO1 and COM2/NO2 paths without distortion or additional biasing - verified across the full −40°C to +85°C temperature range.
How does the MAX20336AEFT+ behave when VCCEN is disconnected or grounded?
When VCCEN is disconnected or tied to GND, the MAX20336AEFT+ enters a high-impedance state: both switches turn off, and all analog terminals (COM1, COM2, NO1, NO2) present >1GΩ isolation. Critically, these pins remain tolerant to −5.5V to +5.5V signals - enabling safe hot-plug operation in USB-C and audio jack interfaces.
Can the MAX20336AEFT+ be used in stereo audio applications requiring matched channel performance?
Yes, the MAX20336AEFT+ is specifically designed for stereo audio routing. Its on-resistance match between channels (ΔRON ≤ ±0.05Ω) and flatness (0.0001Ω typical) ensure near-identical gain and phase response across left/right paths - validated by −85dB crosstalk and 270MHz −3dB bandwidth, making it ideal for portable media player line-out switching.
What package options are available for the MAX20336AEFT+ and how do they differ thermally?
The MAX20336AEFT+ is exclusively offered in the 6-pin FC2QFN package (1.25mm × 1.75mm). Unlike the WLP variants (e.g., MAX20336ENT+), this FC2QFN version has a θJA of 171.6°C/W on a four-layer board - higher than WLP's 95.15°C/W - but provides better mechanical robustness, easier optical inspection, and higher power handling (466.2mW at +70°C) for sustained audio output loads.
