Product details
Overview
The MAX4623CSE+T from Maxim Integrated is a precision dual SPST analog switch with normally open (NO) configuration, 5Ω maximum on-resistance, guaranteed 0.5Ω channel-to-channel RON match, and rail-to-rail analog signal handling from ±4.5V to ±18V bipolar or +4.5V to +36V single supply - used in test equipment signal routing where low distortion and fast switching (<250ns tON) are critical.
For engineers reviewing the MAX4623CSE+T datasheet, MAX4623CSE+T pinout, MAX4623CSE+T application, or MAX4623CSE+T equivalent, key selection criteria include guaranteed break-before-make timing (not applicable), off-leakage <5nA at +85°C, charge injection of 475pC, and SOIC-16 package compatibility with DG405 replacements.
Technical Context
The MAX4623CSE+T implements two independent SPST switches with CMOS/TTL-compatible digital control inputs (IN1/IN2), each driving a NO terminal (NO1/NO2) connected to a common (COM1/COM2). It operates across wide supply ranges without requiring level-shifting logic interfaces.
Its monolithic construction ensures matched on-resistance flatness (∆RON ≤ 0.5Ω over full signal range), low crosstalk (–60dB), and high off-isolation (–62dB at 1MHz), making it suitable for precision multiplexing in data-acquisition systems where channel integrity is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 5Ω max - ensures minimal voltage drop and signal attenuation in low-current analog paths |
| RON Match | 0.5Ω max - enables precise differential or ratiometric measurements between channels |
| Turn-On Time | <250ns - supports high-speed scanning in automated test equipment (ATE) |
| Off-Leakage Current | <5nA at +85°C - preserves signal integrity in high-impedance sensor front-ends |
| Supply Range | ±4.5V to ±18V or +4.5V to +36V - allows flexible system-level power architecture design |
| Rail-to-Rail Signal Handling | VCOM = V+ to V− - supports full dynamic range analog signals without clipping |
| Charge Injection | 475pC - limits transient error during switching in sample-and-hold circuits |
Pinout & Package
MAX4623CSE+T is housed in a 16-pin narrow SOIC (SO/DIP) package with exposed pad not present; pin 14 is GND, pins 1/3/6/8 connect to V−, pins 2/7 are COM1/COM2, pins 4/5/9/16 are NO1/NO2/NO3/NO4 (configured as dual SPST), pins 10/15 are IN1/IN2, pin 12 is V+, pin 13 is VL (logic supply), and pins 11 are internally unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | V− | Negative supply rail input - must be referenced to GND or negative bias source |
| 2, 7 | COM1, COM2 | Switch common terminals - connect to signal source or load return path |
| 4, 5, 9, 16 | NO1, NO2, NO3, NO4 | Normally open switch outputs - conduct only when corresponding INx = HIGH |
| 10, 15 | IN1, IN2 | Digital control inputs - TTL/CMOS compatible; active-high logic |
| 12 | V+ | Positive supply rail input - sets upper analog signal limit |
| 13 | VL | Logic supply voltage - decouples logic threshold from analog rails for stable switching |
| 14 | GND | Ground reference - required for logic interface and internal biasing |
| 11 | N.C. | No internal connection - must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON match | 0.5Ω max between channels - eliminates gain mismatch in dual-path instrumentation |
| Rail-to-Rail® analog handling | VCOM spans full V+ to V− range - avoids external level-shifting circuitry |
| Low off-leakage | <5nA at +85°C - maintains accuracy in µA-range sensor interfaces |
| Fast switching | tON < 250ns, tOFF < 200ns - enables >1MHz multiplexing in real-time DAQ |
| Single/dual supply operation | +4.5V to +36V or ±4.5V to ±18V - simplifies integration into mixed-voltage systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4623ESE+ | Extended temperature range (–40°C to +85°C) vs. 0°C to +70°C; otherwise identical electrical specs and pinout | Suitable for industrial or automotive environments requiring wider thermal operation | Select MAX4623ESE+ when ambient temperature exceeds +70°C or falls below 0°C |
| ADG408BRUZ | 8-channel single-pole switch (not dual SPST); 45Ω typical RON; different pinout and logic polarity | Used in higher-channel-count multiplexing, not direct functional replacement | Choose only if channel count >2 is needed and layout redesign is acceptable |
Compared with MAX4623CSE+T, MAX4623ESE+ offers identical performance with extended temperature rating, while ADG408BRUZ provides more channels but higher on-resistance and incompatible pinout - neither is pin-compatible, so PCB changes are required for either alternative.

FAQ
What is the maximum supply voltage rating for MAX4623CSE+T?
The MAX4623CSE+T supports bipolar supplies up to ±18V and single supplies up to +36V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, with V+ to V− differential limited to +44V. Operation beyond these limits risks permanent damage, and proper sequencing (V+ first, then VL and V−) is required for reliability.
Does MAX4623CSE+T support rail-to-rail analog signal switching?
Yes, the MAX4623CSE+T supports rail-to-rail analog signal handling: the COM and NO terminals can swing from V− to V+ without clipping or distortion. This capability is confirmed in the datasheet's "Input Voltage Range" specification and Typical Operating Characteristics plots, enabling full utilization of the analog supply rails in precision signal paths.
Is MAX4623CSE+T pin-compatible with the DG405 analog switch?
Yes, the MAX4623CSE+T is explicitly specified as a pin-compatible replacement for the DG405. The datasheet confirms identical pin configurations for SOIC-16 packages, including matching assignments for V+, V−, GND, IN1/IN2, COM1/COM2, and NO1–NO4. No PCB layout change is needed when upgrading from DG405 to MAX4623CSE+T.
What is the typical on-resistance flatness of MAX4623CSE+T over its signal range?
The MAX4623CSE+T guarantees on-resistance flatness of ≤5Ω (max) over the full analog signal range, defined as the difference between maximum and minimum RON values measured from V− to V+. At ±15V supplies and +25°C, typical flatness is ≤0.5Ω - critical for minimizing harmonic distortion in audio and instrumentation applications.
Can MAX4623CSE+T operate with a single 5V supply?
No, the MAX4623CSE+T requires a minimum single-supply voltage of +4.5V, but its specified performance (e.g., 5Ω RON, <5nA leakage) is validated down to +4.5V. At exactly +5V, all key parameters remain within datasheet limits; however, logic supply VL must still be provided at +5V, and analog signal range is constrained to 0V to +5V (GND to V+).
