Product details
Overview
MAX4621ESE+ from Maxim Integrated is a precision dual SPST analog switch with 5Ω maximum on-resistance, guaranteed 0.5Ω channel-to-channel RON match, and rail-to-rail analog signal handling (±18V bipolar or +36V single supply). It operates across –40°C to +85°C and targets low-distortion signal routing in test equipment and communication systems.
For engineers reviewing the MAX4621ESE+ datasheet, MAX4621ESE+ pinout, MAX4621ESE+ application, or MAX4621ESE+ equivalent, key selection criteria include guaranteed break-before-make timing (not applicable), leakage <5nA at +85°C, sub-250ns turn-on time, and compatibility with TTL/CMOS logic levels under wide supply ranges.
Technical Context
The MAX4621ESE+ integrates two independent normally-open (NO) analog switches in a monolithic CMOS process. Each switch supports bidirectional rail-to-rail signal switching from V– to V+, with on-resistance flatness ≤5Ω over full signal range and matched RON ≤0.5Ω between channels.
It accepts logic inputs compatible with TTL and CMOS families (VINL ≤0.8V, VINH ≥2.4V) and operates from either single supply (+4.5V to +36V) or dual supplies (±4.5V to ±18V), with separate logic supply pin (VL) enabling level-shifting capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 5Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON match between channels | 0.5Ω max - enables accurate differential or ratiometric measurements without calibration |
| Off-leakage current | <5nA at +85°C - preserves high-impedance node integrity in data-acquisition front-ends |
| Turn-on / turn-off time | <250ns / <200ns - supports high-speed multiplexing in automated test equipment |
| Analog signal range | Rail-to-rail (V– to V+) - allows full utilization of supply rails for unipolar or bipolar signals |
| Logic compatibility | TTL/CMOS - simplifies interface with microcontrollers and FPGAs without level shifters |
| Supply range | +4.5V to +36V (single) or ±4.5V to ±18V (dual) - provides flexibility in industrial and telecom power architectures |
Pinout & Package
MAX4621ESE+ is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO2 | Normally open switch terminals - connect only when corresponding INx is high |
| 2, 7 | COM1, COM2 | Common analog I/O nodes - bidirectional signal path shared with NOx |
| 10, 15 | IN1, IN2 | Digital control inputs - active-high logic controls switch state |
| 12 | V+ | Positive analog supply - sets upper rail for analog signal range |
| 3, 6 | V− | Negative analog supply - sets lower rail for bipolar operation |
| 14 | GND | Ground reference - common return for logic and analog sections |
| 13 | VL | Logic supply input - decouples logic threshold from analog supply, enabling level-shifted control |
| 4, 5, 9, 11, 16 | N.C. | No internal connection - must be left floating or tied to GND per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ signal swing without clipping or distortion in both unipolar and bipolar configurations |
| Guaranteed RON matching | 0.5Ω max mismatch enables precision gain-matching in dual-path instrumentation and sensor interfaces |
| Low charge injection (45pC typ) | Minimizes transient glitches during switching - critical for sample-and-hold and ADC front-end applications |
| Low off-isolation (–62dB at 1MHz) | Reduces crosstalk between inactive channels in high-density multiplexed systems |
| Wide supply flexibility | Single- or dual-supply operation eliminates need for external regulators in mixed-signal systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4621CSE+ | 0°C to +70°C temperature range; identical electrical specs and pinout | Not qualified for extended industrial or avionics environments requiring –40°C operation | Select MAX4621CSE+ only for commercial-grade applications with ambient ≤+70°C |
| ADG465BRMZ-REEL7 | Single SPST switch (not dual); 4.5Ω RON max; –40°C to +125°C; requires no VL pin | Lacks dual-channel integration and logic supply decoupling - increases component count for dual-path designs | Choose ADG465BRMZ-REEL7 only when higher temperature rating or simplified supply scheme outweighs dual-channel benefit |
Compared with MAX4621ESE+, MAX4621CSE+ offers identical performance but lacks extended temperature qualification, while ADG465BRMZ-REEL7 trades dual-channel integration and VL flexibility for wider temperature range and simpler supply architecture.

FAQ
What is the maximum allowable supply voltage for MAX4621ESE+?
The MAX4621ESE+ supports single-supply operation from +4.5V to +36V and dual-supply operation from ±4.5V to ±18V. Absolute maximum ratings specify V+ to GND up to +44V and V− to GND down to –44V, but sustained operation beyond ±18V or +36V violates datasheet specifications and risks device failure. Always observe the recommended operating ranges defined in the Electrical Characteristics tables.
Does MAX4621ESE+ support break-before-make switching?
No, MAX4621ESE+ does not implement break-before-make functionality. It is a normally-open (NO) SPST switch with independent control of each channel. Break-before-make behavior is explicitly guaranteed only for the MAX4622 variant (SPDT configuration); the MAX4621ESE+ truth table confirms simultaneous ON/OFF states per channel without overlap timing guarantees.
Can MAX4621ESE+ operate with VL disconnected or tied to V+?
VL must be actively driven within its specified range (–0.3V to V+ + 0.3V) and is not internally tied to V+. Leaving VL floating violates absolute maximum ratings and may cause undefined logic behavior or latch-up. For single-supply systems, VL should be connected to the same +5V logic rail used by the controlling MCU - it is not optional and enables proper input threshold definition independent of analog supply variations.
What is the typical charge injection value for MAX4621ESE+ and why does it matter?
MAX4621ESE+ exhibits 45pC typical charge injection (Q), measured at V+ = +15V, V− = –15V. This parameter quantifies transient voltage glitch injected into high-impedance nodes (e.g., sample-and-hold capacitors or ADC inputs) during switching. Low Q minimizes settling error and acquisition time - critical in precision data-acquisition systems where even sub-mV errors degrade effective resolution.
Is MAX4621ESE+ pin-compatible with legacy DG401 devices?
Yes, MAX4621ESE+ is explicitly documented as a pin-compatible replacement for the DG401, offering improved on-resistance (5Ω vs. 45Ω), tighter RON matching (0.5Ω vs. unspecified), lower leakage, and faster switching. No PCB changes are required when upgrading from DG401 to MAX4621ESE+, provided supply voltages and logic levels remain within compatible ranges.
