Product details
Overview
MAX4754ETE+ from Maxim Integrated is a quad single-pole double-throw (SPDT) analog switch IC designed for low-distortion audio-signal routing in portable electronics. It features 0.5Ω typical on-resistance, 0.035% THD at 20Hz–20kHz, rail-to-rail signal handling (0V to V+), and operates from +1.8V to +5.5V. It is used in speaker-headset switching circuits where precise impedance matching and minimal signal degradation are critical.
For engineers reviewing the MAX4754ETE+ datasheet, MAX4754ETE+ pinout, MAX4754ETE+ application, or MAX4754ETE+ equivalent, key selection criteria include on-resistance flatness (0.2Ω typ), channel-to-channel RON matching (0.1Ω typ), break-before-make timing (2ns), and UCSP/QFN package compatibility with high-density PCB layouts.
Technical Context
The MAX4754ETE+ implements four independent SPDT switches using CMOS process technology, each with matched NO/NC paths and bidirectional signal capability. Its control logic accepts rail-to-rail inputs up to +5.5V independent of supply voltage, enabling mixed-voltage system interfacing.
It supports full analog signal swing from GND to V+, maintains <0.4Ω RON variation over temperature (−40°C to +85°C), and delivers 10MHz −3dB bandwidth with −90dB crosstalk and −65dB off-isolation at 100kHz - confirming suitability for stereo audio path switching without inter-channel interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.5Ω typical - ensures minimal insertion loss and thermal drift in 32Ω headphone and 8Ω speaker paths. |
| THD + Noise | 0.035% typical at 1VP-P, 20Hz–20kHz - preserves audio fidelity in headset/speaker switching applications. |
| Supply Voltage Range | +1.8V to +5.5V - supports direct integration with Li-ion battery-powered systems and 3.3V/5V logic domains. |
| Channel Matching (ΔRON) | 0.1Ω typical - enables balanced stereo signal routing without amplitude skew between left/right channels. |
| Break-Before-Make Time | 2ns guaranteed - prevents momentary shorting during audio path reconfiguration, eliminating audible pop/click. |
| Off-Isolation | −65dB at 100kHz - suppresses leakage from active to inactive audio paths, critical for multi-source routing. |
| Operating Temperature | −40°C to +85°C - qualified for use in handheld devices exposed to ambient thermal cycling. |

FAQ
What is the maximum analog signal voltage range supported by the MAX4754ETE+?
The MAX4754ETE+ supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +1.8V to +5.5V. This means the device passes signals spanning the full supply range without clipping - for example, 0V to +3.3V when powered from a 3.3V rail. Internal ESD clamps limit absolute max analog voltage to (V+ + 0.3V), ensuring robustness against transient overvoltage.
Does the MAX4754ETE+ require external pull-up or pull-down resistors on its digital control inputs?
No, the MAX4754ETE+ does not require external biasing on INA or INB. Its logic inputs are CMOS-based with rail-to-rail tolerance (up to +5.5V) and specified VIH/VIL thresholds (1.4V/0.5V at V+ = 3V). Driving these pins directly from microcontroller GPIOs - even those operating at different supply voltages - is fully supported without additional components.
Can the MAX4754ETE+ be used to switch DC signals, or is it limited to AC/audio applications?
The MAX4754ETE+ is fully specified for DC-coupled operation: it handles continuous analog signals from 0V to V+ with ±300mA channel current rating and 0.5Ω RON. Its low charge injection (300pC) and flat on-resistance make it suitable for precision DC signal routing, sensor multiplexing, and programmable gain stages - not just audio.
How does the exposed paddle (EP) on the MAX4754ETE+ TQFN package affect thermal and electrical performance?
The exposed paddle on the MAX4754ETE+ must be soldered to a solid GND plane. It reduces thermal resistance by ~30°C/W, lowers junction temperature under load, and improves EMI suppression by providing low-inductance grounding for internal substrate noise. Failure to connect EP to GND degrades THD, increases RON drift, and risks reliability failure at elevated temperatures.
Is the MAX4754ETE+ pin-compatible with the MAX4754AETE+?
Yes, the MAX4754ETE+ and MAX4754AETE+ share identical pinout, package dimensions (16-pin TQFN-EP), and functional block diagram. They differ only in internal logic threshold design and supply current specs - making them drop-in replacements in existing layouts where the lower quiescent current of the 'A' version is not required.
