Product details
Overview
MAX4641EUA+T from Maxim Integrated is a dual SPST analog switch with two normally open (NO) channels, designed for low-voltage signal routing in battery-powered and precision analog 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 <20ns switching times - enabling high-fidelity audio routing and low-distortion data acquisition.
For engineers reviewing the MAX4641EUA+T datasheet, MAX4641EUA+T pinout, MAX4641EUA+T application, or MAX4641EUA+T equivalent, this page provides verified electrical parameters, µMAX package layout, rail-to-rail analog operation details, leakage performance across temperature, and real-world substitution guidance for dual NO switch selection.
Technical Context
The MAX4641EUA+T implements CMOS transmission-gate architecture with integrated logic-level translators, enabling TTL/CMOS-compatible control inputs while supporting rail-to-rail analog signals from GND to V+. Its dual NO configuration isolates both signal paths until actively enabled, eliminating unintended conduction during power-up or logic transitions.
On-resistance variation is tightly controlled: 1Ω flatness over full signal range and 0.6Ω matching between channels ensure minimal gain error in differential or multiplexed sensor interfaces. Low 0.35nA max leakage and 2pC charge injection preserve signal integrity in sample-and-hold and high-impedance measurement circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +1.8V to +5.5V single supply - supports Li-ion, coin-cell, and 3.3V/5V system rails without level shifters |
| RON (max) | 4Ω at +5V - ensures ≤0.2% gain error in 1kΩ load applications |
| RON Matching | 0.6Ω max difference between channels - critical for matched-path instrumentation |
| tON/tOFF | 18ns/12ns typical - enables >25MHz switching in time-division multiplexing |
| Analog Signal Range | Rail-to-rail (GND to V+) - preserves full dynamic range of ADCs and DACs |
| Leakage Current | ±0.35nA max over –40°C to +85°C - avoids offset drift in picoampere-sensitivity circuits |
| THD | 0.018% at 20Hz–20kHz - meets CD-quality audio routing requirements |
Pinout & Package
MAX4641EUA+T is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), pin-compatible with industry-standard SOIC-8 footprints but with 57% smaller area. The exposed pad enhances thermal performance and must be soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | NO1, NO2 | Normally open analog output terminals - conduct only when corresponding IN_ = HIGH |
| 2, 6 | IN1, IN2 | Active-high digital control inputs - TTL/CMOS compatible at +5V; threshold scales with V+ |
| 3, 7 | COM1, COM2 | Common analog input terminals - bidirectional signal path with identical RON in either direction |
| 4 | GND | Ground reference for logic and analog sections - must be low-impedance connection |
| 8 | V+ | Positive supply input - requires local 0.1µF ceramic bypass capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog range | Supports full-scale signal swing from GND to V+, eliminating clipping in 1.8V–5.5V systems |
| Guaranteed RON flatness | 1Ω max variation across 0V–V+ ensures consistent gain in variable-gain amplifiers |
| Low charge injection | 2pC typical - minimizes voltage glitch in sample-and-hold capacitors ≥1nF |
| High off-isolation | –80dB at 1MHz - suppresses crosstalk between adjacent audio or RF signal paths |
| Ultra-low quiescent power | <0.01µW - extends battery life in always-on sensor nodes and portable medical devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NO analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG702BRMZ-REEL | 4.5Ω RON max at +5V; 1.5nA leakage at +85°C; 12ns tON; MSOP-8 package | Higher leakage impacts ultra-low-current sensor front-ends; same µMAX footprint not supported | Select when MSOP-8 board space is available and leakage tolerance >1nA is acceptable |
| TS5A23157DCUR | 0.9Ω RON typ at +3.3V; 100nA leakage at +85°C; 10ns tON; 8-pin VSSOP | Lower RON improves power efficiency but higher leakage degrades precision DC accuracy | Prefer for high-speed digital I/O switching where leakage is non-critical; avoid in precision analog paths |
Compared with ADG702BRMZ-REEL and TS5A23157DCUR, the MAX4641EUA+T uniquely balances ultra-low leakage (0.35nA), tight RON matching (0.6Ω), and rail-to-rail operation - making it optimal for battery-powered precision analog systems where signal fidelity and power efficiency are co-constrained.

FAQ
What is the maximum supply voltage rating for MAX4641EUA+T?
The absolute maximum supply voltage for MAX4641EUA+T is +6V, but operational specification guarantees performance only up to +5.5V. Exceeding +5.5V risks violating the guaranteed RON, leakage, and timing parameters. For reliable long-term operation, V+ must remain within +1.8V to +5.5V per the datasheet's recommended conditions. MAX4641EUA+T includes internal ESD diodes that clamp analog pins to V+ and GND, but sustained overvoltage can cause permanent damage.
Does MAX4641EUA+T support bidirectional analog signal flow?
Yes, MAX4641EUA+T supports fully bidirectional analog signal routing: COM1↔NO1 and COM2↔NO2 operate identically in either direction due to symmetrical CMOS transmission-gate design. RON, leakage, and capacitance values are specified independently of signal direction. However, off-capacitance differs slightly between NO_ and COM_ pins (7pF vs. 7pF typical), so layout symmetry is advised in high-frequency applications. MAX4641EUA+T does not require external polarity considerations for signal path design.
What is the guaranteed RON flatness specification for MAX4641EUA+T at +5V?
At +5V supply, MAX4641EUA+T guarantees RON flatness of 1Ω maximum - defined as the difference between highest and lowest on-resistance measured across the full analog signal range (GND to V+). This ensures consistent gain and minimal harmonic distortion when switching varying-amplitude signals such as audio or sensor outputs. Flatness is tested per device at TA = –40°C to +85°C and is independent of channel matching or absolute RON value.
Can MAX4641EUA+T operate reliably from a +1.8V supply?
Yes, MAX4641EUA+T is fully specified and guaranteed to operate from +1.8V, delivering 30Ω typical RON and functional logic control with scaled thresholds (VIL = 0.4V, VIH = 2.0V). While RON increases versus +5V operation, the device maintains rail-to-rail analog range, sub-nA leakage, and <25ns switching times. MAX4641EUA+T is widely used in coin-cell-powered sensors and wearables where +1.8V operation extends battery life without sacrificing signal integrity.
Is the µMAX package of MAX4641EUA+T RoHS-compliant and lead-free?
Yes, MAX4641EUA+T carries the "+T" suffix indicating tape-and-reel packaging and full RoHS compliance, including lead-free terminations and halogen-free molding compound. The 8-pin µMAX package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is qualified for reflow soldering per IPC/JEDEC J-STD-020. MAX4641EUA+T's exposed thermal pad must be soldered to a PCB ground plane to meet thermal and reliability specifications.
