Product details
Overview
MAX4623CSE from Maxim Integrated is a dual, double-pole/single-throw (DPST), normally open analog switch IC designed for precision signal routing in low-distortion systems. It delivers 5Ω maximum on-resistance with ≤0.5Ω matching between channels, <5nA off-leakage at +85°C, and switching times of <250ns turn-on / <200ns turn-off. It operates from single (+4.5V to +36V) or bipolar (±4.5V to ±18V) supplies and supports rail-to-rail analog signal handling up to ±15V.
For engineers reviewing the MAX4623CSE datasheet, MAX4623CSE pinout, MAX4623CSE application, or MAX4623CSE equivalent, key selection criteria include guaranteed break-before-make timing (per MAX4622 only - not applicable), channel-to-channel RON match tolerance, leakage performance across temperature, supply voltage flexibility, and SOIC-16 package compatibility with legacy DG405 sockets.
Technical Context
The MAX4623CSE implements two independent SPST NO switches fabricated in a monolithic CMOS process, each with matched on-resistance and flat RON (<0.5Ω variation) over the full analog range. Its logic inputs accept TTL/CMOS-compatible levels (0.8V/2.4V thresholds) referenced to VL, while analog terminals (COM/NO) support signals spanning V− to V+.
No internal break-before-make circuitry is present-unlike the MAX4622-making it suitable for non-overlapping control paths where simultaneous conduction is acceptable. All switching characteristics are specified across 0°C to +70°C and validated under both dual-supply (±15V) and single-supply (+12V) conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 5Ω max - ensures minimal signal attenuation and gain error in precision instrumentation paths |
| RON Match | ≤0.5Ω max - enables accurate differential or ratiometric measurements without calibration |
| Off-Leakage (85°C) | <5nA - preserves high-impedance node integrity in data-acquisition front-ends |
| Turn-On Time | <250ns - supports multiplexing at >1MHz sampling rates in automated test equipment |
| Supply Range | +4.5V to +36V single or ±4.5V to ±18V dual - accommodates industrial, avionics, and telecom power architectures |
| Rail-to-Rail Signal | VCOM/VNO = V− to V+ - allows full-swing AC/DC signal switching without level-shifting circuitry |
| Logic Compatibility | TTL/CMOS - interfaces directly with microcontrollers, FPGAs, and ASICs without level translators |
Pinout & Package
MAX4623CSE is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, footprint-compatible with industry-standard 16-pin SOIC layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Digital Logic Input (IN1, IN2) | Active-high control lines; drive corresponding switch ON when logic high (≥2.4V) |
| 2, 7 | Switch Common Terminal (COM1, COM2) | Analog current path input; connects to load or signal source |
| 4, 5, 9, 16 | Switch Normally Open Terminal (NO1–NO4) | Analog output path; closed only when respective INx = high |
| 6, 11, 14 | Ground / Not Connected | Pins 6 and 14 are GND; Pin 11 is NC - no internal connection, must be left floating or grounded per layout |
| 12 | Positive Supply (V+) | Main analog supply rail; supports up to +36V in single-supply mode |
| 13 | Logic Supply (VL) | Separate logic reference; typically +5V, decoupled locally to reduce noise coupling |
| 3, 15 | Negative Supply (V−) | Required for bipolar operation; supports down to −18V; tied to GND in single-supply configs |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON Match | ≤0.5Ω between channels - eliminates mismatch-induced errors in dual-path signal conditioning |
| Rail-to-Rail Analog Handling | Full V− to V+ signal swing supported - avoids clipping in ±12V or +24V systems |
| Low Charge Injection | 475pC typical - minimizes transient glitches during switching in sample-and-hold circuits |
| Low Off-Capacitance | 34pF typical (NO/NC) - preserves high-frequency signal integrity and reduces crosstalk |
| Pin-Compatible Replacement | Direct drop-in for DG405 - enables upgrade without PCB redesign or layout changes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4623ESE | Same functionality and pinout; rated for −40°C to +85°C industrial temperature range | Suitable for avionics, outdoor base stations, and extended-temperature industrial controllers | Select MAX4623ESE when operating outside 0°C–70°C ambient or requiring AEC-Q200-aligned qualification evidence |
| ADG408BRUZ | 8-channel single-pole analog multiplexer; 45Ω typical RON, no guaranteed RON match spec | Better suited for low-cost, moderate-precision multiplexing where channel count >2 is required | Choose ADG408BRUZ only if higher channel density offsets its 9× higher RON and lack of matching guarantee |
Compared with MAX4623CSE, the MAX4623ESE offers identical electrical behavior with extended thermal robustness, while the ADG408BRUZ trades precision and dual-channel integration for higher channel count and lower cost-making it unsuitable for matched-path or low-RON applications.

FAQ
What is the maximum supply voltage rating for MAX4623CSE in single-supply operation?
The MAX4623CSE supports a single positive supply from +4.5V to +36V. Absolute maximum rating is +44V referenced to GND, but operation above +36V violates the specified functional range and may compromise RON stability, leakage, and reliability. Always observe the +36V limit for compliant design.
Does MAX4623CSE support break-before-make switching like MAX4622?
No, MAX4623CSE does not implement break-before-make timing. It is a dual SPST NO switch with independent control inputs (IN1, IN2); simultaneous activation of both switches results in concurrent conduction. Break-before-make is exclusive to the MAX4622 (SPDT) variant and is not present in MAX4623CSE.
Can MAX4623CSE operate with V− tied to GND and V+ at +12V?
Yes, MAX4623CSE fully supports single-supply operation with V− = GND and V+ = +12V. In this configuration, analog signals on COM/NO pins must remain within 0V to +12V, and VL should be supplied at +5V. All key specs-including 5Ω RON, <250ns tON, and <5nA leakage-are validated under this condition.
Is the MAX4623CSE pinout compatible with the DG405 analog switch?
Yes, MAX4623CSE is explicitly specified as a pin-compatible replacement for the DG405. Pin assignments for IN1/IN2, COM1/COM2, NO1–NO4, V+, V−, VL, and GND match identically in the 16-pin SOIC package, allowing direct substitution without PCB modification.
What is the typical charge injection value for MAX4623CSE, and why does it matter?
MAX4623CSE exhibits 475pC typical charge injection. This parameter quantifies transient voltage glitch injected onto the COM node during switching; low values like this prevent corruption in sample-and-hold circuits, integrators, or high-impedance sensor interfaces where even sub-mV disturbances degrade accuracy.
