Product details
Overview
MAX20336ENT+ 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, −114dB THD+N at 1VRMS, and operates from a single +1.6V to +5.5V supply. Designed for portable audio routing in smartphones and tablets, it supports bidirectional AC/DC-biased signal paths without external negative rails.
For engineers reviewing the MAX20336ENT+ datasheet, MAX20336ENT+ pinout, MAX20336ENT+ application, or MAX20336ENT+ equivalent, key selection criteria include its ultra-low RON flatness (0.0001Ω), ±30kV HBM ESD protection on analog terminals, GPIO-compatible VCCEN enable, and guaranteed operation across −40°C to +85°C in the 1.308mm × 0.828mm WLP package.
Technical Context
The MAX20336ENT+ implements a DPST topology with two independent COM–NO switch pairs (COM1/NO1 and COM2/NO2), each supporting bidirectional signal flow and rail-to-rail analog voltage handling beyond VCCEN. Its control logic is supply-enabled only-no separate digital control pin-so switching state is determined solely by VCCEN presence.
Internally, the device uses high-voltage tolerant MOSFET structures to achieve −5.5V to +5.5V analog signal range while maintaining 65μA typical supply current at 1.6V. Thermal shutdown activates at +150°C with +25°C hysteresis, and all analog pins withstand ±30kV HBM ESD without latchup-even when unpowered.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20336AEFT+ | Same electrical specs but in 6-pin FC2QFN (1.25mm × 1.75mm); higher θJA (171.6°C/W) vs. WLP (95.15°C/W). | Preferred where reworkability or standard QFN assembly infrastructure exists; less suitable for ultra-thin mobile form factors. | Select MAX20336AEFT+ when board assembly process requires exposed-pad QFN handling or thermal relief via heatsinking is needed. |
| TMUX1574RTER | SPDT configuration (single COM, dual NO/NC); 0.5Ω RON; no Beyond-the-Rails support; −3.3V to +3.3V analog range. | Requires external level-shifting for signals beyond supply rails; lacks ±30kV HBM rating on analog pins. | Choose TMUX1574RTER only if SPDT topology suffices and system signals stay within ±3.3V; not drop-in for MAX20336ENT+'s DPST or rail-exceeding use cases. |
Compared with MAX20336AEFT+, the MAX20336ENT+ offers superior thermal performance and smaller footprint but no exposed thermal pad; versus TMUX1574RTER, it delivers true rail-exceeding operation and industry-leading ESD robustness-making it irreplaceable in high-fidelity, space-constrained portable audio designs.

FAQ
What is the maximum analog signal voltage the MAX20336ENT+ can handle?
The MAX20336ENT+ supports analog signals from −5.5V to +5.5V independent of VCCEN voltage-a feature called Beyond-the-Rails™ operation. This means even with VCCEN as low as +1.6V, the device passes full-range audio or video signals without clipping or distortion. Absolute maximum ratings confirm −6V to +6V tolerance on NO_, COM_, and NC pins, with continuous operation guaranteed across the full −5.5V to +5.5V span.
Does the MAX20336ENT+ require a separate digital control signal?
No, the MAX20336ENT+ does not require a separate digital control signal. It uses a supply-enable architecture: applying VCCEN powers the internal switch matrix and closes both DPST paths; pulling VCCEN to GND disables the switches and places all analog terminals in high-impedance mode. This eliminates the need for CB or EN logic pins-unlike the MAX20337 variant-and simplifies GPIO-driven power sequencing.
Can the MAX20336ENT+ be used in audio applications requiring low THD+N?
Yes, the MAX20336ENT+ is optimized for high-fidelity audio. It achieves −114dB THD+N at 1VRMS into a 32Ω load-measured per standard audio test conditions (20Hz–20kHz, 0V DC bias). Combined with 0.19Ω typical RON and 0.0001Ω RON flatness, this ensures minimal harmonic generation and amplitude nonlinearity across the full signal swing, making it suitable for premium smartphone and tablet audio routing.
What package type is used for the MAX20336ENT+?
The MAX20336ENT+ uses a 6-bump wafer-level package (WLP) with dimensions 1.308mm × 0.828mm and 0.4mm bump pitch. Its top marking is "AM", and the package code is N60K1+1. This ultra-compact, leadless package is designed for fine-pitch PCB assembly in mobile devices and requires land patterns specified in Maxim Application Note 1891.
How does the MAX20336ENT+ behave when VCCEN is unpowered?
When VCCEN is unpowered (0V), the MAX20336ENT+ enters a true high-impedance state: all analog terminals (COM1, COM2, NO1, NO2) present >1GΩ isolation and can safely withstand −5.5V to +5.5V signals without leakage or damage. This behavior protects downstream circuitry during system sleep modes and enables hot-swap-safe interface designs-critical for USB-C and accessory-detection applications.
