Product details
Overview
The MAX4620ESD from Maxim Integrated is a low-voltage, ±15kV ESD-protected, quad single-pole/single-throw (SPST) analog switch with four normally open (NO) channels, 70Ω max on-resistance at +5V, 0.5nA off-leakage at +25°C, and rail-to-rail signal handling - used in battery-powered audio routing and automated test equipment where mechanical relay replacement is required.
For engineers reviewing the MAX4620ESD datasheet, MAX4620ESD pinout, MAX4620ESD application, or MAX4620ESD equivalent, this page delivers verified electrical specs, SO package terminal mapping, ESD protection architecture, switching distortion performance, and pin-compatible alternatives for low-voltage analog signal path design.
Technical Context
The MAX4620ESD implements CMOS-based SPST switches with integrated bidirectional SCR structures on NO pins to enable ±15kV HBM and IEC 1000-4-2 air-gap ESD protection without latchup. Each channel operates bilaterally with TTL/CMOS-compatible control inputs and supports rail-to-rail analog signals from 0V to V+ (2V–12V).
Its switching behavior is defined by guaranteed on-resistance flatness (2Ω typ at +5V), matching (0.5Ω typ), and low charge injection (5pC), enabling high-fidelity signal routing in audio and data-acquisition systems where THD < 0.015% and >300MHz –3dB bandwidth are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610ESA+ | Single-channel, 8-pin SO; 60Ω max RON at +5V; no integrated ESD SCRs - requires external protection | Not suitable for direct NO-pin ESD exposure; limited to protected board environments | Select when only one switch is needed and system-level ESD is already managed |
| ADG1412BRUZ | Quad SPST, 16-pin TSSOP; 1.8Ω max RON at +5V; ±20kV HBM ESD; higher supply current (20µA) | Superior on-resistance and ESD rating but larger footprint and higher quiescent power | Choose for ultra-low RON and enhanced ESD margin where board space allows |
Compared with MAX4610ESA+, the MAX4620ESD offers quad integration and on-chip ±15kV ESD protection; versus ADG1412BRUZ, it trades lower on-resistance for smaller SO package and lower supply current - optimizing for space-constrained, battery-operated systems.

FAQ
What is the maximum supply voltage for the MAX4620ESD?
The MAX4620ESD supports a single-supply voltage range from +2V to +12V. Its absolute maximum rating is +13V referenced to GND. When operating near +12V, a minimum 0.1µF ceramic bypass capacitor must be placed directly between V+ and GND at the device pins to suppress ESD transients and ensure reliable SCR turn-off behavior. Exceeding +13V risks permanent damage.
Does the MAX4620ESD require external ESD protection components?
No, the MAX4620ESD does not require external ESD protection on its NO pins. It integrates on-die bidirectional SCRs that provide ±15kV Human Body Model and ±15kV IEC 1000-4-2 air-gap ESD protection. However, V+ must still be bypassed with a 0.1µF capacitor to ground to shunt residual ESD current, and external current limiting (<35mA) on NO-connected sources is recommended to ensure SCR turn-off after an event.
How many independent switches does the MAX4620ESD contain, and what is their configuration?
The MAX4620ESD contains four independent single-pole/single-throw (SPST) analog switches, all configured as normally open (NO). Each switch connects its NO pin to its corresponding COM pin when the associated INx control input is driven HIGH. This differs from the MAX4630ESD (four NC switches) and MAX4640ESD (two NO + two NC), making the MAX4620ESD ideal for applications requiring default-open signal paths.
What is the on-resistance matching specification for the MAX4620ESD, and why does it matter?
The MAX4620ESD guarantees on-resistance matching of 0.5Ω typical (3Ω max) between channels at +5V. This tight matching ensures uniform gain, timing, and signal attenuation across all four switched paths - critical in applications like multi-channel audio mixing, phased-array sensor interfaces, or precision multiplexed ADC front-ends where channel-to-channel consistency directly impacts measurement accuracy and system linearity.
Can the MAX4620ESD operate with a 3.3V supply, and how does performance change?
Yes, the MAX4620ESD operates fully across +2.7V to +3.6V at 3.3V nominal. At +3V supply, on-resistance increases to 120Ω max (vs. 70Ω at +5V), on-resistance flatness degrades to 12Ω typ (vs. 2Ω), and turn-on time rises to 250ns typ (vs. 90ns). These shifts are documented in the +3V electrical characteristics table and remain within specification - confirming suitability for modern low-voltage embedded systems without performance compromise.
