Product details
Overview
MAX4651ESE+T from Maxim Integrated is a quad, single-pole single-throw (SPST), normally closed (NC) analog switch IC operating from a single +1.8V to +5.5V supply. It delivers 4Ω max on-resistance at +5V, 0.2Ω max on-resistance matching between channels, and rail-to-rail analog signal handling up to V+. Designed for low-distortion signal routing in battery-powered test equipment and data-acquisition systems.
For engineers reviewing the MAX4651ESE+T datasheet, MAX4651ESE+T pinout, MAX4651ESE+T application, or MAX4651ESE+T equivalent, key selection criteria include verified NC configuration, SO-16 package compatibility, sub-0.2Ω RON matching across temperature, <12ns tOFF, and -75dB off-isolation at 1MHz - all confirmed for this exact part number.
Technical Context
The MAX4651ESE+T implements four independent CMOS SPST switches with normally closed logic behavior: each switch conducts when its INx input is logic low (0V), and opens when high (≥2.4V at +5V). Its architecture ensures matched conduction paths and minimal charge injection (2pC typical), critical for sample-and-hold and precision multiplexing.
All four switches share a common +5.5V absolute maximum supply rating, tolerate rail-to-rail analog inputs (GND to V+), and maintain flat on-resistance (≤0.8Ω max variation over 0–V+ signal range at +5V). Off-leakage is specified at ±0.1nA at +25°C, supporting high-impedance sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +5V - ensures minimal voltage drop and power loss in signal paths carrying ≤50mA. |
| On-Resistance Matching (ΔRON) | 0.2Ω max across channels - enables precise gain/offset matching in multi-channel instrumentation. |
| Off-Isolation | -75dB at 1MHz - suppresses crosstalk between inactive and active signal paths in dense routing. |
| Turn-Off Time (tOFF) | 12ns typical - supports high-speed switching in automated test and digital sampling applications. |
| Rail-to-Rail Signal Range | GND to V+ - allows full utilization of supply headroom without clipping in unipolar signal chains. |
| Supply Voltage Range | +1.8V to +5.5V - enables direct interface with 1.8V, 3.3V, and 5V logic and analog domains. |
| Off-Leakage Current | ±0.1nA max at +25°C - preserves accuracy in high-impedance sensor and integrator circuits. |
Pinout & Package
MAX4651ESE+T is housed in a 16-pin SO (Small Outline) package with standard 150-mil body width and 1.27mm pitch. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Digital control inputs | Active-low logic: switch closes (NC path conductive) when input = 0V; opens when ≥2.4V (at +5V). |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Input/output node shared between NC and COM paths; must be connected to signal source/load. |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog terminals | Conductive path to COM when corresponding INx = 0V; open when INx = high. |
| V+ (Pin 13) | Positive supply | Single supply input (1.8V–5.5V); powers internal CMOS switch array and level-shifting circuitry. |
| GND (Pin 5) | Ground reference | Return path for supply current and logic/switch reference; must be low-impedance for leakage control. |
| N.C. (Pins 4, 12) | No-connect terminals | Not internally bonded; left floating or tied to GND per layout best practice - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPST NC topology | Four independent, fail-safe closed-path switches - eliminates signal interruption during power-up or logic fault. |
| 0.8Ω max RON flatness | Ensures consistent gain and linearity across full analog input range (0V to V+), critical for audio and measurement fidelity. |
| TTL/CMOS-compatible inputs | Accepts standard 1.8V–5.5V logic thresholds - interoperable with microcontrollers, FPGAs, and ASICs without level shifters. |
| -100dB crosstalk at 1MHz | Prevents interference between adjacent switched channels in multi-signal routing (e.g., video/audio matrix). |
| 2pC typical charge injection | Minimizes voltage glitch on high-Z nodes - essential for precision sample-and-hold and ADC front-end stability. |
Applications
| Battery-Powered Data Acquisition | Automated Test Equipment (ATE) |
|---|---|
Use Scenario: Multiplexing sensor outputs (thermocouples, strain gauges) into a low-power ADC in portable field instruments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4652ESE+T | Quad SPST NO (normally open) configuration vs. MAX4651ESE+T's NC - complementary logic sense and default-open state. | Suitable where default signal isolation is required (e.g., safety-critical shutdown paths), not default continuity. | Select MAX4652ESE+T only if system logic requires active-high enable and failsafe open behavior. |
| ADG1412BRUZ | Higher RON (1.8Ω typ at +5V), wider supply (±15V dual or +5V single), but superior THD (0.002%) and lower charge injection (0.2pC). | Better suited for high-fidelity audio and precision instrumentation where distortion and glitch energy are primary constraints. | Choose ADG1412BRUZ when THD <0.01% or charge injection <0.5pC is mandatory; accept larger SO-16 footprint and higher cost. |
Compared with MAX4652ESE+T, the MAX4651ESE+T provides guaranteed continuity at power-up - critical for fail-safe signal paths. Against ADG1412BRUZ, it trades ultra-low distortion for lower cost, smaller die size, and tighter RON matching - optimal for cost-sensitive, multi-channel routing where <0.02% THD suffices.

FAQ
What is the default state of the switches in MAX4651ESE+T?
The MAX4651ESE+T features four normally closed (NC) SPST switches. When all IN1–IN4 inputs are at logic low (0V), all COM-to-NC paths are conductive. Applying logic high (≥2.4V at +5V) opens each respective switch. This fail-safe NC behavior ensures signal continuity during power-up or controller reset - a key design feature confirmed in the MAX4651ESE+T truth table and functional diagrams.
Does MAX4651ESE+T support rail-to-rail analog signals?
Yes, MAX4651ESE+T supports rail-to-rail analog signals from GND to V+. Its CMOS switch architecture allows analog voltages spanning the full supply range without clipping or distortion, as verified in the "Detailed Description" and "Electrical Characteristics" sections of the datasheet. This capability is explicitly guaranteed for the MAX4651ESE+T variant and applies across its entire +1.8V to +5.5V supply range.
What is the maximum allowable supply voltage for MAX4651ESE+T?
The absolute maximum supply voltage for MAX4651ESE+T is +6V, but the recommended operating range is +1.8V to +5.5V. Operation beyond +5.5V risks permanent damage, as stated in the Absolute Maximum Ratings table. All electrical specifications - including 4Ω max RON and 0.2Ω matching - are validated only within the +1.8V to +5.5V range, making +5.5V the practical upper limit for reliable MAX4651ESE+T functionality.
Can MAX4651ESE+T be used with 1.8V logic control signals?
Yes, MAX4651ESE+T accepts 1.8V logic inputs. Its VIH threshold is specified at 2.0V min for +3V supply and 2.4V min for +5V supply, but the device operates correctly with 1.8V logic when V+ = 1.8V - confirmed in the "+1.8V Operation" feature list and Electrical Characteristics tables. At 1.8V supply, logic high is recognized above ~0.9V, enabling direct interface with 1.8V microcontrollers without level translation.
What is the thermal performance of MAX4651ESE+T in SO-16 package?
In the SO-16 package, MAX4651ESE+T has a power dissipation limit of 640mW at +70°C ambient, derating by 8mW/°C above that temperature. This corresponds to a junction-to-ambient thermal resistance (θJA) of approximately 156°C/W. The specification is explicitly listed in the Absolute Maximum Ratings table for the "16-Pin SO" variant and applies directly to MAX4651ESE+T, ensuring safe operation under continuous 50mA per channel load at industrial temperatures.
