Product details
Overview
MAX4651ESE+ from Maxim Integrated is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch operating from a single +1.8V to +5.5V supply. It delivers 4Ω maximum on-resistance at +5V, 0.2Ω maximum on-resistance matching between channels, and rail-to-rail analog signal handling up to V+. It is used in low-distortion audio routing and battery-powered data-acquisition systems where mechanical relay replacement is required.
For engineers reviewing the MAX4651ESE+ datasheet, MAX4651ESE+ pinout, MAX4651ESE+ application, or MAX4651ESE+ equivalent, key selection criteria include on-resistance flatness (0.8Ω max), off-isolation (−75dB at 1MHz), turn-on/turn-off times (11ns/6ns typ at +5V), leakage current (0.1nA max at +25°C), and SO-16 package compatibility with legacy PCB layouts.
Technical Context
The MAX4651ESE+ implements four independent NC SPST switches using matched CMOS transmission-gate architecture, enabling precise analog signal path control without polarity inversion. Its logic inputs are TTL/CMOS-compatible, with VIH = 2.4V and VIL = 0.8V at +5V supply, and it supports rail-to-rail analog voltages from GND to V+.
Dynamic performance is characterized by low charge injection (2pC), minimal crosstalk (−100dB at 1MHz), and stable on-capacitance (32pF) and off-capacitance (16pF). The device guarantees break-before-make timing only in the MAX4653 variant - not applicable to MAX4651ESE+.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +5V - ensures minimal voltage drop and signal attenuation in precision analog paths. |
| On-Resistance Matching | 0.2Ω max across channels - enables matched gain/attenuation in multi-channel instrumentation. |
| On-Resistance Flatness | 0.8Ω max over full signal range - maintains consistent channel linearity for audio and sensor signals. |
| Off-Leakage Current | 0.1nA max at +25°C - preserves signal integrity in high-impedance sample-and-hold or sensor front-ends. |
| Turn-On / Turn-Off Time | 11ns / 6ns typical at +5V - supports fast multiplexing in data-acquisition and communications circuits. |
| Off-Isolation | −75dB at 1MHz - suppresses crosstalk between inactive and active signal paths. |
| Supply Voltage Range | +1.8V to +5.5V - enables direct integration into Li-ion battery-powered and mixed-voltage systems. |
Pinout & Package
MAX4651ESE+ is housed in a 16-pin SO (Small Outline) package, 3.9mm × 9.9mm body, 1.27mm pitch, RoHS-compliant, with standard SOIC footprint compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-low logic controls NC closure; logic "0" connects COMx to NCx (no inversion). |
| COM1–COM4 | Analog common terminals | Signal input/output nodes routed through internal NC switches when enabled. |
| NC1–NC4 | Normally closed analog terminals | Default-closed paths; open only when corresponding INx = logic "1". |
| V+ | Positive supply | Single supply rail supporting rail-to-rail analog operation from GND to V+. |
| GND | Ground reference | Return path for analog signals and digital logic; must be low-impedance for THD < 0.02%. |
| N.C. | No connection | Pins 3, 6, 11, 14 are unconnected - no internal bond wire or circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full-swing signals from GND to V+, eliminating level-shifting in ±5V or 3.3V systems. |
| Low on-resistance flatness (0.8Ω max) | Minimizes harmonic distortion (THD = 0.02%) across audio and sensor bandwidths. |
| TTL/CMOS-compatible logic inputs | Direct interface with microcontrollers and FPGAs without level translators at +5V or +3V logic. |
| Ultra-low off-leakage (0.1nA) | Enables accurate DC-coupled sampling in high-resolution ADC front-ends and medical sensors. |
| Low charge injection (2pC) | Reduces settling error in sample-and-hold and switched-capacitor circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4652ESE+ | Quad NO (normally open) configuration instead of NC; identical RON, timing, and package. | Suitable where default-open signal paths are required (e.g., safety interlocks, default-isolated sensors). | Select MAX4652ESE+ only when system logic requires de-energized-open behavior rather than de-energized-closed. |
| ADG1412BRUZ | 4Ω RON at +5V but higher 0.5Ω matching spec; −85dB off-isolation; TSSOP-16 package only. | Better isolation for RF-adjacent analog routing; not pin-compatible due to different pin mapping (IN/COM order differs). | Choose ADG1412BRUZ when off-isolation > −80dB is critical and layout revision is acceptable. |
Compared with MAX4652ESE+, the MAX4651ESE+ provides fail-safe closed-path behavior ideal for monitoring circuits; compared with ADG1412BRUZ, it offers superior SO-16 footprint compatibility and tighter on-resistance matching for precision instrumentation, albeit with lower off-isolation.

FAQ
What is the maximum supply voltage rating for MAX4651ESE+?
The MAX4651ESE+ has an absolute maximum supply voltage (V+ to GND) of +6V. However, its specified operational range is +1.8V to +5.5V. Operating beyond +5.5V may cause permanent damage or parametric shift. The MAX4651ESE+ must never be subjected to supply transients exceeding +6V, even momentarily, as internal protection diodes clamp only within the −0.3V to (V+ + 0.3V) range.
Does MAX4651ESE+ support rail-to-rail analog signals?
Yes, the MAX4651ESE+ supports rail-to-rail analog signals - meaning it can pass voltages from GND to V+ without clipping or distortion. This capability is enabled by its CMOS transmission-gate architecture and is confirmed across the full operating temperature range (−40°C to +85°C) and supply range (+1.8V to +5.5V). Signal integrity remains intact up to the absolute maximum ratings.
What is the on-resistance matching specification for MAX4651ESE+?
The MAX4651ESE+ guarantees on-resistance matching of ≤0.2Ω maximum between any two channels, measured at V+ = +4.5V to +5.5V and ICOM = 10mA. This parameter holds across the full operating temperature range (−40°C to +85°C) and ensures consistent gain or attenuation across all four switches in multi-channel signal conditioning circuits.
Can MAX4651ESE+ be used with a +3.3V supply?
Yes, the MAX4651ESE+ operates fully specified down to +1.8V and is compatible with +3.3V supplies. At +3.3V, its typical on-resistance is 7Ω (max), on-resistance flatness is 2.5Ω (max), and tON/tOFF are 13ns/7ns typical. All logic thresholds (VIH = 2.0V, VIL = 0.4V) and leakage specs remain valid, making it suitable for modern low-voltage embedded systems.
Is MAX4651ESE+ pin-compatible with other variants in the MAX465x family?
Yes, the MAX4651ESE+, MAX4652ESE+, and MAX4653ESE+ share identical 16-pin SO package pinouts and electrical footprints. Pin functions (IN1–IN4, COM1–COM4, NC1–NC4, V+, GND, N.C.) are positionally identical across all three variants. Only the internal switch configuration (NC/NO/mixed) differs - allowing hardware reuse with firmware logic adaptation.
