Product details
Overview
MAX4641EUA+ from Maxim Integrated is a dual single-pole/single-throw (SPST) analog switch with two normally open (NO) channels, designed for low-voltage signal routing in battery-powered and precision systems. It operates from +1.8V to +5.5V, delivers 4Ω max on-resistance at +5V, 0.6Ω RON matching between channels, 1Ω RON flatness, and sub-20ns switching times - enabling high-fidelity audio routing and low-distortion data acquisition.
For engineers reviewing the MAX4641EUA+ datasheet, MAX4641EUA+ pinout, MAX4641EUA+ application, or MAX4641EUA+ equivalent, key selection criteria include guaranteed RON performance across supply voltage and temperature, rail-to-rail analog signal handling, ultra-low leakage (<0.35nA), and µMAX package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4641EUA+ implements CMOS transmission-gate architecture with integrated logic-level translators, enabling TTL/CMOS-compatible control inputs only at +5V supply while maintaining full analog functionality down to +1.8V. Its bidirectional analog path supports rail-to-rail signal swing, with ESD protection diodes clamping NO/NC/COM pins to V+ and GND.
Each channel features matched RON and flat RON over the full signal range, critical for precision multiplexing and sample-and-hold circuits. Dynamic performance includes -97dB crosstalk at 1MHz, -80dB off-isolation, and 0.018% THD - confirming suitability for high-fidelity audio and low-noise instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into Li-ion and 3.3V/5V mixed-signal systems without level shifters. |
| RON (max, +5V) | 4Ω - ensures minimal signal attenuation and gain error in precision sensor interfaces and DAC output switching. |
| RON Matching | 0.6Ω max between channels - preserves channel-to-channel signal integrity in differential or dual-path applications. |
| RON Flatness | 1Ω max over full analog range - maintains consistent gain and linearity across ±VCOM swing, critical for audio and video routing. |
| tON/tOFF | 18ns/12ns typical - supports >25MHz switching rates for high-speed data acquisition and digital waveform generation. |
| Leakage Current | <0.35nA over -40°C to +85°C - prevents DC offset drift in high-impedance sensor front-ends and battery-monitoring circuits. |
| THD | 0.018% at 20Hz–20kHz - meets fidelity requirements for professional audio signal paths and medical instrumentation. |
Pinout & Package
MAX4641EUA+ is housed in an 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), optimized for compact portable designs. The package requires standard reflow soldering per JEDEC J-STD-020 and thermal pad grounding is not required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | NO1, NO2 | Normally open analog switch terminals - conduct only when corresponding IN_ is high; bidirectional signal path with 7pF off-capacitance. |
| 2, 6 | IN1, IN2 | Logic control inputs - accept TTL/CMOS levels; drive internal gate drivers; input current <0.1µA ensures minimal MCU GPIO loading. |
| 3, 7 | GND | Analog and digital ground reference - must be connected to system ground plane; shared return for all leakage and supply currents. |
| 4 | COM1 | Common analog terminal for first SPST switch - connects to NO1 when IN1 = high; bidirectional with rail-to-rail voltage support. |
| 8 | V+ | Positive supply input - bypass with 0.1µF ceramic capacitor to GND; supplies analog switches and logic core; max 6V absolute rating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full V+ to GND swing without clipping - eliminates need for external biasing in AC-coupled audio or sensor interfaces. |
| Guaranteed RON flatness (1Ω) | Maintains constant insertion loss across signal amplitude - essential for linear gain control and calibrated measurement systems. |
| Low charge injection (2pC) | Minimizes voltage glitch during switching - prevents settling errors in sample-and-hold and ADC front-end multiplexing. |
| High off-isolation (-80dB @ 1MHz) | Reduces crosstalk between active and inactive channels - critical for multi-channel audio routing and simultaneous-sampling DAQ. |
| Ultra-low quiescent power (<0.01µW) | Enables always-on signal path control in energy-harvesting and coin-cell-powered IoT nodes. |
Applications
| Audio Signal Routing | Portable Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG702BRMZ-REEL | 4.5Ω RON max at +5V; 16ns tON; 8-lead MSOP package; no guaranteed RON flatness spec. | Higher RON tolerance may impact gain accuracy in precision DAQ; MSOP footprint differs from µMAX. | Select ADG702BRMZ-REEL only if MSOP layout is fixed and RON flatness is not required. |
| TS5A23157DGSR | 0.9Ω RON max at +5V; 10ns tON; 10-pin VSSOP; supports +1.65V to +5.5V; no RON matching guarantee. | Lower RON benefits low-voltage sensor interfaces, but lack of RON matching limits differential applications. | Choose TS5A23157DGSR for ultra-low RON needs where channel matching is secondary to on-resistance. |
Compared with ADG702BRMZ-REEL and TS5A23157DGSR, MAX4641EUA+ uniquely guarantees both RON matching (0.6Ω) and flatness (1Ω) - making it the only option among the three qualified for precision dual-path instrumentation and calibrated multiplexing.

FAQ
What is the maximum supply voltage rating for MAX4641EUA+?
The MAX4641EUA+ has an absolute maximum supply voltage (V+) rating of +6V. Operation above +5.5V risks permanent damage. For reliable long-term use, the recommended operating range is +1.8V to +5.5V, with guaranteed RON, switching time, and leakage specifications validated across this span. Always bypass V+ to GND with a 0.1µF ceramic capacitor near the MAX4641EUA+ package.
Does MAX4641EUA+ support rail-to-rail analog signal operation?
Yes, MAX4641EUA+ supports true rail-to-rail analog signal operation - meaning signals from GND to V+ can pass unattenuated through the NO1/COM1 and NO2/COM2 paths. This capability is enabled by its CMOS transmission-gate design and internal level-shifting circuitry, eliminating the need for external bias networks in AC-coupled or single-supply systems using the MAX4641EUA+.
What is the guaranteed RON matching specification for MAX4641EUA+ at +5V?
The MAX4641EUA+ guarantees RON matching of ≤0.6Ω between its two SPST channels when operated at +5V supply, measured across the full analog signal range and temperature (-40°C to +85°C). This parameter - defined as RON(MAX) − RON(MIN) - ensures minimal gain mismatch in dual-path applications such as differential signal routing or balanced audio switching using the MAX4641EUA+.
Can MAX4641EUA+ be used with a +3.3V supply?
Yes, MAX4641EUA+ is fully specified and functional at +3.3V. At this supply, typical RON is 6Ω (max 8Ω), tON/tOFF remain <22ns/<11ns, and leakage stays <0.35nA. Logic inputs require VIH ≥ 2.0V and VIL ≤ 0.4V - compatible with standard 3.3V CMOS outputs. However, TTL compatibility is only assured at +5V, so ensure controller logic thresholds align with the MAX4641EUA+'s +3.3V input specs.
What package type is used for MAX4641EUA+?
MAX4641EUA+ uses the 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), a thermally enhanced variant of SOIC with exposed paddle not required for thermal relief. This RoHS-compliant package supports standard reflow profiles and provides superior power dissipation versus traditional 8-SO packages. Pinout and footprint are identical to other µMAX-packaged Maxim analog switches, including MAX4642EUA+ and MAX4643EUA+.
