Product details
Overview
MAX4701EUE+ from Maxim Integrated is a low-voltage, dual double-pole/double-throw (DPDT) CMOS analog switch operating from a single +1.8V to +5.5V supply. It features 75Ω max on-resistance at +3V, 35ns turn-on time, rail-to-rail signal handling, and 1nA max leakage at +85°C. It is used in audio/video routing and battery-powered communications circuits where compact size and low-power switching are critical.
For engineers reviewing the MAX4701EUE+ datasheet, MAX4701EUE+ pinout, MAX4701EUE+ application, or MAX4701EUE+ equivalent, key selection criteria include guaranteed break-before-make timing, channel matching ≤4Ω, -76dB off-isolation at 1MHz, and compatibility with 1.8V logic inputs when powered from +3V.
Technical Context
The MAX4701EUE+ implements two independent DPDT switches, each controlled by separate digital inputs (IN1/IN2), enabling simultaneous configuration of two isolated signal paths. Its CMOS architecture supports bidirectional analog signal flow across COM/NO/NC terminals with rail-to-rail voltage range and guaranteed break-before-make operation (tBBM ≤1ns at +3V).
It operates without external logic supply-unlike the MAX4702-and uses standard TTL/CMOS-compatible control thresholds (VIH = +1.4V, VIL = +0.5V at +3V). On-resistance flatness remains ≤12Ω over full signal range, and crosstalk is limited to -79dB at 1MHz, supporting high-fidelity signal routing in dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into 1.8V, 2.7V, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 75Ω max at +3V - ensures minimal insertion loss and voltage drop for precision analog signals up to ±10mA. |
| RON Matching | 4Ω max between channels - maintains amplitude balance in differential or parallel signal paths. |
| Turn-On/Off Time | tON = 35ns, tOFF = 20ns (at +3V) - supports high-speed multiplexing in data acquisition and video switching applications. |
| Off-Isolation | -76dB at 1MHz - suppresses coupling between inactive channels, critical for multi-source audio/video routing. |
| Leakage Current | ±1nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-critical standby modes. |
| Bandwidth | 250MHz -3dB - supports composite video, USB 1.1, and other baseband analog signals without attenuation. |
Pinout & Package
MAX4701EUE+ is housed in a 16-pin TSSOP package (3mm × 4.4mm body, 0.65mm pitch), optimized for space-constrained portable designs. The exposed pad is absent-unlike TQFN variants-simplifying thermal design but requiring standard solder-reflow profile validation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | IN1, IN2 | Dual independent digital control inputs for DPDT sections; compatible with 1.8V logic at +3V supply. |
| 3, 4 | NO2, COM2 | Normally-open and common terminal of second DPDT switch; bidirectional signal path. |
| 5, 6 | NC2, GND | Normally-closed terminal (switch 2) and system ground reference-must be connected to PCB ground plane. |
| 7–10 | NO3, COM3, NC3, NO4 | Terminals for third and fourth SPDT segments forming second DPDT structure; all support rail-to-rail analog swing. |
| 11–13 | COM4, NC4, V+ | Common/NC of fourth switch and positive supply input; V+ must be decoupled with ≥100nF ceramic capacitor. |
| 14–16 | NO1, COM1, NC1 | First DPDT switch terminals; COM1 serves as primary signal entry point for channel 1 routing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping-enables direct interfacing with ADCs, DACs, and op-amps. |
| Guaranteed break-before-make | tBBM ≤1ns prevents momentary shorting during state transitions-essential for avoiding signal glitches in audio mixing. |
| Low on-resistance flatness | 12Ω max variation across full signal range-minimizes harmonic distortion in audio and video signal paths. |
| High off-isolation & low crosstalk | -76dB off-isolation and -79dB crosstalk at 1MHz-preserves channel separation in multi-input AV equipment. |
| 1.8V logic compatibility | VIH = +1.4V, VIL = +0.5V at +3V supply-allows direct connection to low-voltage microcontrollers without level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4699ETE+ | Same dual DPDT function but in 4mm × 4mm TQFN; higher thermal performance; no TSSOP option. | Preferred for thermally constrained designs needing better power dissipation; not footprint-compatible with MAX4701EUE+. | Select when board layout allows larger QFN and thermal management is prioritized over assembly simplicity. |
| ADG732BRUZ | 32-channel SPST switch (not DPDT); 4.5Ω RON at +5V; requires 3V logic supply; different control architecture. | Suitable for high-channel-count digital multiplexing-not for DPDT signal inversion or polarity switching. | Choose only for large-scale channel selection where DPDT topology is unnecessary and lower RON justifies redesign. |
Compared with MAX4701EUE+, the MAX4699ETE+ offers superior thermal capability in a non-pin-compatible QFN package, while the ADG732BRUZ provides higher channel density at the cost of topology mismatch and no native DPDT functionality-making MAX4701EUE+ optimal for compact, dual-path analog routing.

FAQ
What is the maximum supply voltage rating for MAX4701EUE+?
The absolute maximum supply voltage (V+) for MAX4701EUE+ is +6V. Operation beyond this risks permanent damage. For reliable long-term use, the recommended operating range is +1.8V to +5.5V. At +5V, MAX4701EUE+ achieves 40Ω max on-resistance and 18ns max turn-on time-key parameters verified across -40°C to +85°C.
Does MAX4701EUE+ support rail-to-rail analog signal switching?
Yes, MAX4701EUE+ supports true rail-to-rail analog signal handling: signals from GND to V+ pass through the switch with minimal distortion. This is confirmed by its specified analog signal range (0V to V+) and <12Ω on-resistance flatness over that full range-critical for interfacing with ADCs, DACs, and op-amps without signal clipping.
Is MAX4701EUE+ pin-compatible with MAX4701ETE+?
No, MAX4701EUE+ (16-pin TSSOP) is not pin-compatible with MAX4701ETE+ (16-pin 3mm × 3mm TQFN). Pin assignments differ: TSSOP uses IN1/IN2 on pins 1–2, while TQFN places them on pins 2 and 10. Layout redesign and footprint change are required-no mechanical or electrical drop-in replacement exists between these packages.
What is the logic threshold voltage for MAX4701EUE+ at +3V supply?
At +3V supply, MAX4701EUE+ has VIH = +1.4V (min) and VIL = +0.5V (max), making it compatible with 1.8V logic families. These thresholds are guaranteed over temperature (-40°C to +85°C) and ensure robust noise margin in noisy portable environments-verified in the Electrical Characteristics table under "Digital I/O" section.
Can MAX4701EUE+ be used in audio applications requiring low THD?
Yes, MAX4701EUE+ delivers 0.02% THD (typical) at 20Hz–20kHz with 2.5Vp-p signal into 600Ω load-validated in the Electrical Characteristics table. Combined with 75Ω RON, 12Ω flatness, and -79dB crosstalk, it meets fidelity requirements for headset switching, microphone selection, and line-level audio routing without external buffering.
