Product details
Overview
MAX4701EGE 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 16-pin 3mm × 3mm QFN packaging. It is used in audio/video routing and battery-powered communications circuits where compact size and low-leakage switching are critical.
For engineers reviewing the MAX4701EGE datasheet, MAX4701EGE pinout, MAX4701EGE application, or MAX4701EGE equivalent, key selection criteria include guaranteed break-before-make timing, channel-to-channel RON matching ≤4Ω, -76dB off-isolation at 1MHz, and 1.8V-logic-compatible digital inputs when powered from +3V.
Technical Context
The MAX4701EGE implements two independent DPDT switches, each controlled by separate logic inputs (IN1/IN2 for Switches 1–2; IN3/IN4 for Switches 3–4), enabling discrete SPDT control per pole pair. Its CMOS architecture ensures bidirectional signal flow, rail-to-rail analog voltage support (0V to V+), and guaranteed break-before-make operation with tBBM ≤1ns at +3V.
It uses a single positive supply (V+) without requiring a negative rail or split supply, and its digital inputs are compatible with 1.8V logic levels when V+ = +3V (VIH = +1.4V, VIL = +0.5V). No separate logic supply (VL) is needed - unlike the MAX4702 - confirming its dual-control, non-VL architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into 2-cell Li-ion or 3.3V/5V systems without level-shifting. |
| On-Resistance (RON) | 75Ω max at +3V supply - ensures minimal signal attenuation and distortion in audio and precision analog paths. |
| RON Matching | ≤4Ω max between channels - maintains amplitude balance across stereo or differential signal pairs. |
| Turn-On / Turn-Off Time | tON = 35ns, tOFF = 20ns (V+ = +3V) - supports high-speed multiplexing in data acquisition and video switching. |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between active and inactive signal paths in dense PCB layouts. |
| Leakage Current | ±1nA max at +85°C - preserves signal integrity in high-impedance sensor or battery-monitoring circuits. |
| Bandwidth | 250MHz -3dB - supports composite video, USB 1.1, and baseband RF signal routing without roll-off. |
Pinout & Package
MAX4701EGE is housed in a 16-pin, 3mm × 3mm, 0.85mm height QFN package with exposed thermal pad (EP). The package supports reflow soldering and provides low-inductance grounding via the EP connection to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | NO1, NO2 | Normally open terminals for Switches 1 and 2 - connect to signal sources when corresponding INx = logic high. |
| 2, 14 | COM1, COM2 | Common terminals for Switches 1 and 2 - serve as bidirectional I/O nodes routed to system interconnects. |
| 3, 13 | NC1, NC2 | Normally closed terminals for Switches 1 and 2 - provide default path continuity when INx = logic low. |
| 4, 12 | IN1, IN2 | Digital control inputs for Switches 1 and 2 - TTL/CMOS-compatible with 1.8V logic thresholds at V+ = +3V. |
| 5, 11 | NO3, NO4 | Normally open terminals for Switches 3 and 4 - enable independent routing of secondary analog channels. |
| 6, 10 | COM3, COM4 | Common terminals for Switches 3 and 4 - allow expansion to quad-path signal management without additional ICs. |
| 7, 9 | NC3, NC4 | Normally closed terminals for Switches 3 and 4 - maintain fail-safe signal continuity during power-up or control loss. |
| 8 | GND | Ground reference for analog and digital domains - must be connected to low-impedance system ground plane. |
| 16 | V+ | Positive supply input - powers internal switch array and logic; requires local 100nF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | tBBM ≤1ns ensures no momentary short between NC and NO paths - prevents signal glitches or bus contention. |
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates clipping in full-scale audio, sensor, or DAC output paths. |
| Low on-resistance flatness | 12Ω max variation over full signal range - maintains consistent gain and linearity across input voltage swing. |
| High off-isolation & low crosstalk | -76dB off-isolation and -79dB crosstalk at 1MHz - isolates sensitive analog sections from noisy digital domains. |
| 1.8V logic compatibility | VIH = +1.4V, VIL = +0.5V at V+ = +3V - interfaces directly with modern ultra-low-power MCUs 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 |
|---|---|---|---|
| MAX4699EGE | Same dual-DPDT function but in 4mm × 4mm QFN; higher RON (85Ω max at +3V) and no IN3/IN4 pins - only two SPDT pairs. | Used where board space permits larger package and only two switch groups are required. | Select MAX4699EGE if layout allows 4mm × 4mm footprint and dual-control simplicity outweighs density needs. |
| ADG732BRUZ | 32-channel SPST switch (not DPDT); 4.5Ω RON at +3V; requires serial SPI control instead of parallel logic inputs. | Suited for high-channel-count, software-configured routing - not for real-time hardware-controlled DPDT toggling. | Choose ADG732BRUZ only when programmable channel mapping and lower RON justify added MCU overhead and SPI interface complexity. |
Compared with MAX4699EGE and ADG732BRUZ, MAX4701EGE uniquely delivers dual-DPDT functionality in the smallest QFN footprint (3mm × 3mm) with parallel 1.8V-logic-compatible control - making it optimal for space-constrained, low-latency analog routing where hardware-switched redundancy is required.

FAQ
What is the maximum supply voltage rating for MAX4701EGE?
The absolute maximum supply voltage (V+) for MAX4701EGE is +6V. Operation beyond this risks permanent damage. For reliable long-term use, the recommended supply range remains +1.8V to +5.5V. Exceeding +6V violates Absolute Maximum Ratings and may compromise internal ESD structures or oxide integrity. Always observe derating curves in the datasheet when operating near limits.
Does MAX4701EGE require a separate logic supply voltage (VL)?
No, MAX4701EGE does not require a VL pin or external logic supply. Unlike the MAX4702, it derives all logic thresholds from V+, supporting 1.8V-compatible inputs (VIH = +1.4V, VIL = +0.5V) when V+ = +3V. This simplifies power design by eliminating a second supply rail - a key differentiator confirmed in the Pin Description table and Detailed Description section of the datasheet.
How many independent switch channels does MAX4701EGE implement?
MAX4701EGE implements four independent SPDT switch sections arranged as two DPDT groups: Switches 1–2 are controlled by IN1/IN2, and Switches 3–4 by IN3/IN4. Each SPDT section has dedicated NO, NC, and COM terminals, totaling eight analog I/O pins plus control and supply. This structure is explicitly shown in the Pin Configurations and Applications Information sections.
What is the guaranteed on-resistance matching between channels for MAX4701EGE?
MAX4701EGE guarantees ∆RON ≤4Ω maximum between any two channels at V+ = +2.7V and TA = -40°C to +85°C. This specification - defined as RON(MAX) – RON(MIN) - ensures amplitude consistency across stereo audio, differential sensor, or matched filter paths without calibration. Typical matching is tighter (≤2Ω), but design must rely on the 4Ω worst-case bound.
Can MAX4701EGE handle analog signals beyond the supply rails?
No, MAX4701EGE cannot safely handle analog signals beyond GND or V+. Its Absolute Maximum Ratings specify that voltages on COM_, NO_, or NC_ pins must stay within -0.3V to (V+ + 0.3V). Exceeding these clamps internal diodes and risks latch-up or damage. For overvoltage tolerance, external protection diodes (as shown in Figure 1 of the datasheet) are required - but they reduce effective signal range by ~0.7V.
