Product details
Overview
The MAX4652EGP from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with four normally open (NO) channels, operating from a single +1.8V to +5.5V supply. It delivers 4Ω max on-resistance at +5V, 0.2Ω max on-resistance matching between channels, and rail-to-rail analog signal handling - ideal for low-distortion audio routing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4652EGP datasheet, MAX4652EGP pinout, MAX4652EGP application, or MAX4652EGP equivalent, key selection criteria include verified on-resistance flatness (0.8Ω max), sub-15ns switching times (tON/tOFF), -100dB crosstalk at 1MHz, and compatibility with TTL/CMOS logic in compact 20-pin QFN (4×4mm) packaging.
Technical Context
The MAX4652EGP implements CMOS transmission-gate architecture optimized for low-voltage operation down to +1.8V, enabling direct integration into portable and ultra-low-power systems. Its matched RON and flat RON profile across the full signal range (GND to V+) ensure minimal gain error and THD of 0.02% in precision signal-path applications.
Each channel features independent digital control (IN1–IN4), with NO terminals electrically isolated when off (off-isolation -75dB at 1MHz) and low charge injection (2pC typical) critical for sample-and-hold integrity. The device requires no external biasing and supports bidirectional analog signals without polarity constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +5V - ensures <10mV drop at 2.5mA signal current, preserving accuracy in sensor front-ends. |
| On-Resistance Matching | 0.2Ω max - guarantees ≤0.5% gain mismatch across four channels in multi-channel instrumentation. |
| On-Resistance Flatness | 0.8Ω max at +5V - maintains consistent attenuation over full rail-to-rail input swing (0V to +5V). |
| Turn-On/Off Time | tON = 14ns max, tOFF = 8ns max - supports >30MHz switching in high-speed multiplexing without pulse distortion. |
| Crosstalk | -100dB at 1MHz - prevents audible interference in stereo audio routing or adjacent ADC channel coupling. |
| Off-Leakage Current | 0.1nA max at +25°C - enables use in picoampere-level current measurement circuits without calibration drift. |
| Supply Voltage Range | +1.8V to +5.5V - allows direct interface with Li-ion battery (3.0–4.2V), 3.3V logic, and legacy 5V systems. |
Pinout & Package
MAX4652EGP is housed in a 20-pin QFN package (4mm × 4mm, 0.5mm pitch) with exposed pad for thermal enhancement. Pin 1 is located at top-left corner (mark dot adjacent), and the package is RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | TTL/CMOS-compatible; logic high (>2.4V at +5V) closes corresponding NO switch. |
| COM1–COM4 | Analog common terminals | Bidirectional signal path entry/exit points; must remain within GND–V+ range. |
| NO1–NO4 | Normally open analog outputs | Connect to COMx only when respective INx = high; 16pF off-capacitance minimizes loading. |
| V+ | Positive supply | Single power rail; bypass with 0.1µF ceramic capacitor to GND for noise immunity. |
| GND | Ground reference | Common return for analog and digital domains; connect directly to system ground plane. |
| N.C. | No connection | Pins 3, 5, 6, 10, 11, 16, 17, 18, 19, 20 - internally unconnected; leave floating or ground per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal support | Enables full-swing signal routing from GND to V+ without clipping or distortion in ±0.5V headroom designs. |
| Low on-resistance flatness (0.8Ω max) | Maintains constant insertion loss across entire input voltage range - critical for precision gain-setting networks. |
| Ultra-low charge injection (2pC typ) | Reduces sampling error in S/H circuits and DAC output buffering, eliminating need for additional settling compensation. |
| -100dB crosstalk at 1MHz | Prevents signal bleed between adjacent audio or sensor channels, meeting Class-D amplifier and medical EEG routing requirements. |
| Single-supply +1.8V operation | Eliminates level-shifting circuitry in coin-cell or energy-harvesting systems, reducing BOM count and PCB area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Higher RON (1.3Ω typ at +5V), wider supply (±5V dual or +3V to +16.5V single), 20-TSSOP package | Better suited for higher-voltage industrial sensors; lacks +1.8V operation and 20-QFN footprint | Select when bipolar signal handling or >5.5V operation is required; not drop-in for MAX4652EGP layouts. |
| TMUX1574RTER | Lower RON (0.5Ω typ), same 20-QFN package, but only +1.08V to +3.6V supply range and no -40°C rating | Ideal for USB-C accessory detection or smartphone peripheral muxing; unsuitable for extended temperature or 5V systems | Choose for cost-sensitive consumer apps below +3.6V; verify thermal derating for continuous 50mA loads. |
Compared with ADG1412BRUZ and TMUX1574RTER, the MAX4652EGP uniquely balances ultra-low-voltage operation (+1.8V), guaranteed -40°C to +85°C performance, and industry-standard 20-QFN footprint - making it optimal for ruggedized portable instrumentation where supply headroom and temperature range are non-negotiable.

FAQ
What is the maximum supply voltage rating for the MAX4652EGP?
The MAX4652EGP has an absolute maximum supply voltage (V+ to GND) of +6V, but its specified operational range is +1.8V to +5.5V. Operating continuously above +5.5V risks permanent damage per Absolute Maximum Ratings. For reliable long-term use in 5V systems, maintain V+ at 4.5V–5.5V as defined in the Electrical Characteristics table - the MAX4652EGP delivers guaranteed 4Ω max RON and 0.2Ω matching only within this range.
Does the MAX4652EGP support bidirectional analog signal flow?
Yes, the MAX4652EGP supports fully bidirectional analog signal flow on all COMx–NOx paths. Its CMOS transmission-gate structure imposes no inherent directionality - signals can pass from COM to NO or NO to COM with identical RON, flatness, and leakage characteristics. This enables flexible routing in both source-driven (e.g., sensor to ADC) and load-driven (e.g., DAC to amplifier) configurations without redesigning the MAX4652EGP interface.
What is the thermal performance of the MAX4652EGP in its 20-pin QFN package?
The MAX4652EGP in 20-pin QFN (4×4mm) has a thermal resistance θJA of 50°C/W (typical, JEDEC JESD51-7 standard) and a derating factor of 20mW/°C above +70°C ambient. At 1600mW max continuous dissipation (TA = +70°C), it sustains full 50mA per channel with <10°C junction rise. For sustained 4-channel operation at 50mA each, ensure ≥2cm² copper pour under the exposed pad and ≤40°C ambient to keep Tj <125°C - the MAX4652EGP's rated maximum junction temperature.
How does the MAX4652EGP handle logic-level compatibility with modern microcontrollers?
The MAX4652EGP accepts TTL- and CMOS-compatible logic inputs: VIH = 2.4V min (at +5V supply) and VIL = 0.8V max, aligning with 3.3V and 5V MCU GPIO thresholds. Input current is ±100nA max, eliminating need for series resistors or level shifters. When interfaced with 1.8V MCUs, the MAX4652EGP remains functional down to +1.8V supply - but VIH drops to 2.0V, so ensure the MCU's VOH exceeds 2.0V at load to guarantee reliable switching of the MAX4652EGP.
Can the MAX4652EGP be used in audio line-level switching without external buffering?
Yes, the MAX4652EGP is qualified for line-level audio switching without external op-amps. Its 4Ω RON introduces <0.05dB insertion loss into 10kΩ line loads, 0.02% THD meets CD-quality standards, and -100dB crosstalk prevents channel bleed in stereo paths. For 600Ω professional audio, add a unity-gain buffer post-switch to avoid RON-induced frequency response roll-off - the MAX4652EGP itself handles the signal routing cleanly, preserving fidelity up to 20kHz.
