Product details
Overview
MAX4611CPD from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with four normally closed (NC) channels. It operates from a single +2V to +12V supply, delivers ≤100Ω on-resistance at +5V, matches channel on-resistance within 4Ω max, and supports rail-to-rail analog signal handling (GND to V+). It is used in battery-powered audio routing and low-voltage data-acquisition systems where leakage-critical switching is required.
For engineers reviewing the MAX4611CPD datasheet, MAX4611CPD pinout, MAX4611CPD application, or MAX4611CPD equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with functional and packaging distinctions.
Technical Context
The MAX4611CPD implements four independent NC analog switches using CMOS transmission-gate architecture, each controlled by a TTL/CMOS-compatible digital input (IN1–IN4) with guaranteed logic thresholds of +0.8V (low) and +2.4V (high) at +5V supply. Its internal structure ensures matched on-resistance across all channels and flat on-resistance (<18Ω variation) over the full signal range.
All switches conduct when inputs are logic low and open when high; no external biasing is needed. The device handles analog signals from GND to V+ without level-shifting, and its <2nA off-leakage at +85°C enables precision sample-and-hold and sensor multiplexing in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery or industrial rails without level shifters |
| On-Resistance (max) | 100Ω at +5V - limits voltage drop to ≤100mV at 1mA, preserving signal integrity in low-level sensor paths |
| On-Resistance Match | ≤4Ω between channels - ensures balanced gain/attenuation in differential or multi-channel signal routing |
| Off-Leakage Current | ≤2nA at +85°C - prevents measurable error accumulation in >1s hold-time sample-and-hold circuits |
| Analog Signal Range | GND to V+ - supports true rail-to-rail AC/DC coupling without clamping diodes or external bias |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V at +5V) - interfaces directly with microcontrollers and FPGAs without glue logic |
| Bandwidth | 300MHz on-channel - preserves rise/fall times for video and fast digital control signals up to ~100Mbps |
Pinout & Package
MAX4611CPD is supplied in a 14-pin plastic DIP package (0°C to +70°C operating range), with through-hole mounting and RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog terminals - conduct to COMx when INx = LOW; open when INx = HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common analog nodes - connect to signal source/load; must be routed with controlled impedance for RF-sensitive apps |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - accept 0.8V/2.4V logic thresholds; drive directly from 5V MCU GPIOs |
| 7 | GND | Digital/analog ground reference - must be star-connected to minimize switching noise coupling into analog paths |
| 14 | V+ | Positive supply for analog and digital circuitry - requires local 0.1µF ceramic bypass capacitor placed <2mm from pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates need for external level-shifting in mixed-supply systems |
| Guaranteed on-resistance match | ≤4Ω max mismatch between any two channels - critical for matched filter banks or phase-coherent multiplexing |
| Low off-leakage current | ≤2nA at +85°C - enables >100MΩ effective isolation for high-impedance sensor front-ends |
| ESD protection | >2kV per Method 3015.7 - reduces need for external TVS diodes in handheld or field-deployable equipment |
| Flat on-resistance profile | ≤18Ω variation over full signal range - maintains consistent gain/attenuation across ±2.5V audio or sensor signals |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data-Acquisition Systems |
|---|---|
Use Scenario: Switching stereo line-level signals between multiple sources (e.g., Bluetooth module, mic input, DAC output) in portable speakers. IC Role / Device Role / Timing Role: Quad NC switch enabling simultaneous mute of all outputs during source transition; no pop/click due to break-before-make behavior. Use Value: 100Ω RON and <2nA leakage preserve SNR >95dB and prevent DC offset drift across 8-hour battery operation. |
Use Scenario: Multiplexing 16 thermistor or RTD inputs into a single 24-bit sigma-delta ADC in environmental monitoring hardware. IC Role / Device Role / Timing Role: Precision analog switch array providing channel selection with minimal series resistance and leakage-induced offset. Use Value: 4Ω max RON match ensures <0.01% gain error across channels; rail-to-rail support allows direct connection to unbuffered sensor bridges. |
| Sample-and-Hold Circuits | Communication Signal Switching |
Use Scenario: Capturing fast transient waveforms (e.g., pulse oximeter photodiode output) with >1Msps sampling in wearable medical devices. IC Role / Device Role / Timing Role: Low-charge-injection (1–5pC) NC switch isolating hold capacitor during acquisition phase. Use Value: 5pC max charge injection limits voltage glitch to <500µV on 10nF hold capacitors - avoids reacquisition delays. |
Use Scenario: Selecting between RF front-end paths (e.g., GPS L1, cellular LTE, Wi-Fi 2.4GHz) in multi-radio IoT gateways. IC Role / Device Role / Timing Role: High-bandwidth (300MHz) analog switch routing baseband I/Q signals prior to upconversion. Use Value: 300MHz bandwidth supports clean passage of 100MHz IF signals; 80dB crosstalk prevents inter-path interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611CSD+ | Same electrical specs, but in 14-pin narrow SO package - smaller footprint, surface-mount only | Preferred for space-constrained PCBs; requires reflow assembly instead of through-hole | Select when board area is limited and automated SMT assembly is available |
| ADG1411BRZ | Quad SPST NC switch with lower RON (1.8Ω typ), wider supply (±15V or +5V to +36V), but higher leakage (20nA @ +85°C) | Better for high-precision instrumentation; less suitable for ultra-low-leakage sample-and-hold | Choose for low-RON priority in powered systems; avoid where sub-5nA leakage is mandatory |
Compared with MAX4611CPD, MAX4611CSD+ offers identical performance in a compact SO package ideal for density-optimized designs, while ADG1411BRZ trades ultra-low leakage for significantly lower on-resistance and broader supply flexibility-making it better suited for powered test equipment than battery-operated sensing.

FAQ
What is the maximum supply voltage for MAX4611CPD?
The absolute maximum supply voltage for MAX4611CPD is +13V referenced to GND. Operation above +12V is possible but requires strict adherence to layout guidelines: a 0.1µF ceramic bypass capacitor must be placed within 2mm of the V+ pin, and supply overshoot must be limited to <13.0V differential to avoid permanent damage. At +12V, MAX4611CPD achieves 45Ω typical on-resistance.
Does MAX4611CPD support rail-to-rail analog signals?
Yes, MAX4611CPD supports analog signals from GND to V+ without clipping or distortion. This rail-to-rail capability is inherent to its CMOS transmission-gate architecture and enables direct interface with unbuffered sensors, audio codecs, and DAC outputs - eliminating external level-shifting components in designs using +3.3V or +5V supplies.
What is the on-resistance match specification for MAX4611CPD?
MAX4611CPD guarantees on-resistance match of ≤4Ω maximum between any two channels at +25°C and +5V supply. This tight matching ensures uniform signal attenuation across all four NC switches, which is essential for applications like multi-channel calibration, differential signal routing, and matched filter banks where gain consistency is critical.
Can MAX4611CPD be used with 3.3V logic controllers?
Yes, MAX4611CPD accepts TTL/CMOS logic inputs with thresholds of +0.8V (low) and +2.4V (high) at +5V supply, making it fully compatible with standard 3.3V GPIOs that swing from 0V to 3.3V. No level shifter is needed - the 3.3V high signal exceeds the +2.4V minimum threshold, ensuring reliable turn-off of all NC switches.
What is the off-leakage current of MAX4611CPD at elevated temperature?
MAX4611CPD specifies off-leakage current of ≤2nA at TA = +85°C across all NC and COM terminals. This value is 100% tested at hot temperature and correlated at +25°C. At +70°C (its rated max operating temperature), leakage remains well below 1nA - enabling use in long-hold-time sample-and-hold circuits and high-impedance sensor interfaces where leakage-induced error must stay below 1µV/s.
