Product details
Overview
The MAX4621ESE+T from Maxim Integrated is a precision dual SPST analog switch with 5Ω max on-resistance, 0.5Ω max channel-to-channel RON match, and rail-to-rail analog signal handling (±18V bipolar or +36V single supply). It features <500pA off-leakage at +25°C, <250ns turn-on time, and operates in automatic test equipment and audio-signal routing where low distortion and mechanical relay replacement are required.
For engineers reviewing the MAX4621ESE+T datasheet, MAX4621ESE+T pinout, MAX4621ESE+T application, or MAX4621ESE+T equivalent, key selection criteria include guaranteed break-before-make timing (not applicable), dual-supply compatibility, low charge injection (45pC), and SOIC-16 package suitability for high-density PCB layouts.
Technical Context
The MAX4621ESE+T implements two independent normally-open (NO) analog switches controlled by CMOS/TTL-compatible logic inputs. Its monolithic CMOS design ensures matched on-resistance across channels (≤0.5Ω variation) and flat RON over full signal range (±10V), enabling precision signal routing without gain error.
It supports wide supply ranges: ±4.5V to ±18V bipolar or +4.5V to +36V single supply, with logic supply (VL) decoupled at +5V. Internal protection diodes clamp input signals beyond V+/V−, and all analog pins tolerate (V− − 0.3V) to (V+ + 0.3V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 5Ω max - ensures minimal voltage drop and power loss in signal paths up to ±10V |
| RON match | 0.5Ω max - guarantees consistent gain/attenuation across dual channels in differential or parallel configurations |
| Turn-on time | <250ns - enables fast multiplexing in data-acquisition systems sampling at ≥1MHz |
| Off-leakage current | <5nA at +85°C - preserves signal integrity in high-impedance sensor interfaces |
| Supply range | ±4.5V to ±18V or +4.5V to +36V - supports industrial, avionics, and telecom rails without level-shifting |
| Rail-to-rail analog | VCOM, VNO = V− to V+ - allows full-scale signal switching without clipping in bipolar systems |
| Charge injection | 45pC - limits glitch amplitude in sample-and-hold circuits using 100pF hold capacitors |
Pinout & Package
MAX4621ESE+T is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, footprint compatible with industry-standard SOIC-16 layouts and reflow soldering profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO2 | Normally open switch terminals - connect only when corresponding INx = logic high |
| 2, 7 | COM1, COM2 | Common analog I/O - bidirectional path between COM and NO under active control |
| 10, 15 | IN1, IN2 | Digital control inputs - TTL/CMOS compatible; drive internal switch gates directly |
| 12 | V+ | Positive analog supply - sets upper rail for analog signal range and powers internal circuitry |
| 6, 13 | V−, VL | Negative analog supply and logic supply - VL must be +5V; V− defines lower analog rail |
| 14 | GND | Analog ground reference - separate from digital ground in mixed-signal systems to reduce noise coupling |
| 3, 4, 5, 9, 11, 16 | N.C. | No internal connection - must remain unconnected per datasheet to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON match | 0.5Ω max ensures ≤0.1% gain mismatch between dual channels in instrumentation amplifiers |
| Rail-to-rail analog handling | Supports full V− to V+ signal swing - eliminates need for external level shifters in ±15V systems |
| Low leakage at temperature | <5nA at +85°C maintains accuracy in thermocouple or RTD front-ends without calibration drift |
| Fast switching | <250ns tON/<200ns tOFF enables 2MHz multiplexing in high-speed DAQ without aperture jitter penalty |
| Single/dual supply flexibility | Operates identically on +12V single supply or ±15V bipolar - simplifies BOM across product variants |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRUZ | Single SPST, 4.5Ω max RON, +3V to +16.5V supply, no bipolar support | Limited to single-channel, lower voltage range - unsuitable for ±15V avionics or telecom systems | Select only for low-voltage, single-switch designs where bipolar operation is unnecessary |
| TS5A23157DGSR | Dual SPDT, 0.9Ω typical RON, +1.65V to +5.5V supply, no high-voltage tolerance | SPDT topology and 5.5V max supply preclude use in high-voltage signal routing or relay replacement | Choose only for battery-powered, low-RON consumer audio routing - not a functional substitute |
Compared with ADG465BRUZ and TS5A23157DGSR, the MAX4621ESE+T uniquely supports dual SPST configuration, ±18V bipolar supplies, and guaranteed RON matching - making it irreplaceable in precision high-voltage multiplexing where channel consistency and rail-to-rail signal integrity are mandatory.

FAQ
What is the maximum supply voltage rating for MAX4621ESE+T?
The MAX4621ESE+T supports absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V, with recommended operating ranges of ±4.5V to ±18V (bipolar) or +4.5V to +36V (single supply). Exceeding these limits risks permanent damage due to internal diode breakdown or oxide stress, as confirmed in the Absolute Maximum Ratings table.
Does MAX4621ESE+T support break-before-make switching?
No, the MAX4621ESE+T does not implement break-before-make functionality - it is a normally-open (NO) SPST switch with independent control of each channel. Break-before-make is only guaranteed for the MAX4622 variant (SPDT), as explicitly stated in the Features section and Truth Tables. Using MAX4621ESE+T in applications requiring overlap-free switching requires external timing control.
What is the guaranteed on-resistance flatness for MAX4621ESE+T?
The MAX4621ESE+T guarantees on-resistance flatness of ∆RON ≤ 5Ω max over the full analog signal range (VCOM = ±10V), defined as the difference between maximum and minimum RON measured across the signal swing. This specification ensures minimal harmonic distortion in audio and instrumentation applications, as verified in the Electrical Characteristics tables for both dual- and single-supply conditions.
Can MAX4621ESE+T operate with VL disconnected or floating?
No, VL (pin 13) must be connected to a stable +5V supply as specified in the Pin Description and Electrical Characteristics sections. The logic interface circuitry requires this dedicated 5V rail for proper CMOS/TTL input threshold definition and internal gate drive. Leaving VL floating causes undefined logic states, increased supply current, and potential latch-up - confirmed by the "VL to GND" absolute rating of −0.3V to (V+ + 0.3V) and functional diagrams.
Is MAX4621ESE+T pin-compatible with DG401?
Yes, the MAX4621ESE+T is explicitly documented as a pin-compatible replacement for the DG401, offering improved performance including lower on-resistance (5Ω vs. 35Ω typical), tighter RON matching (0.5Ω vs. unspecified), and enhanced leakage specs. This compatibility is stated in the General Description and confirmed by identical SOIC-16 pinouts and terminal functions in the Pin Configurations diagram.
