Product details
Overview
MAX4747EBE from Maxim Integrated is a low-voltage, quad SPST analog switch with normally open (NO) configuration, operating from +2V to +11V and handling rail-to-rail signals. It delivers 50Ω max on-resistance at +3V, 3.5Ω max channel matching, <0.1nA leakage at +25°C, and 0.5nW typical quiescent power-ideal for precision signal routing in portable medical and audio devices.
For engineers reviewing the MAX4747EBE datasheet, MAX4747EBE pinout, MAX4747EBE application, or MAX4747EBE equivalent, this device supports battery-powered systems requiring ultra-low leakage, tight RON matching, and minimal charge injection in compact UCSP packaging.
Technical Context
The MAX4747EBE implements CMOS-based bidirectional analog switching with TTL/CMOS-compatible digital control inputs. Its four independent NO switches are fully isolated when off, exhibiting -72dB off-isolation and -84dB crosstalk at 1MHz.
Designed for single-supply operation, it guarantees rail-to-rail analog signal handling across its full supply range (+2V to +11V), with on-resistance flatness of ≤9Ω over the signal range at +3V and ≤5Ω at +5V-enabling high-fidelity signal integrity in data-acquisition front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +11V - enables direct integration into 3.3V, 5V, and higher-voltage battery systems without level-shifting. |
| On-Resistance (RON) | 50Ω max at +3V - ensures minimal signal attenuation and gain error in sensor interface and audio paths. |
| RON Matching | 3.5Ω max between channels at +3V - critical for matched gain/attenuation in differential or multi-channel routing. |
| Leakage Current | <0.1nA at +25°C - preserves accuracy in high-impedance glucose meter and pH sensor front-ends. |
| Off-Isolation | -72dB at 1MHz - suppresses coupling between inactive channels in A/V routing applications. |
| Charge Injection | 7pC typical - minimizes voltage glitches during switching in sample-and-hold and multiplexer circuits. |
| Bandwidth | 250MHz - supports wideband signal routing including audio, baseband IF, and low-speed video. |
Pinout & Package
MAX4747EBE is packaged in a 16-bump UCSP (2mm × 2mm), optimized for space-constrained portable designs. The chip-scale package reduces PCB area by >70% versus TSSOP alternatives while maintaining thermal performance via bump-level interconnects.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3, D4, D3 | COM1–COM4 | Common analog terminals - bidirectional connection points for each SPST switch; must be routed with controlled impedance for signal integrity. |
| B1, A2, C4, D2 | NO1–NO4 | Normally open analog outputs - connect only when corresponding IN_ is high; zero DC path when off. |
| C1, A4, B4, D1 | IN1–IN4 | Digital control inputs - TTL/CMOS compatible; drive high (+V+) or low (GND) for reliable switching with <1µA input leakage. |
| C3 | GND | Digital ground reference - requires low-inductance connection to system ground plane to minimize switching noise. |
| B2 | V+ | Single positive supply - powers both analog and digital sections; bypass with 0.1µF capacitor near the pin for stability at high V+. |
| A2, A4, D1, D3 | N.C. | No internal connection - left floating on PCB; no routing or stitching required. |
Key Features
| Feature | Design Value |
|---|---|
| 2mm × 2mm UCSP | Reduces board area by >70% vs. 14-pin TSSOP - essential for slim handhelds and wearable medical devices. |
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping - eliminates need for external biasing in unipolar sensor interfaces. |
| 0.5nW typical quiescent power | Extends battery life in always-on monitoring systems (e.g., continuous glucose meters) with negligible standby drain. |
| Guaranteed <0.1nA leakage | Preserves measurement accuracy in high-Z electrode circuits where leakage would introduce offset errors. |
| TTL/CMOS logic compatibility | Accepts standard 3.3V or 5V logic levels without external translators - simplifies host MCU interface design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4747EUD | 14-pin TSSOP package; same electrical specs but larger footprint (4.4mm × 5mm) and higher thermal resistance. | Suitable for prototyping or cost-sensitive industrial boards where UCSP reflow is unavailable. | Select when manual assembly, legacy PCB tooling, or thermal derating above +70°C is required. |
| ADG1419BCPZ-REEL7 | Quad SPST, 4.5Ω RON max at +5V; higher supply current (200nA typ); 20V absolute max rating. | Better for higher-voltage industrial sensors but consumes >400× more quiescent power than MAX4747EBE. | Choose only if >11V operation or lower RON at +5V is mandatory-and battery life is secondary. |
Compared with MAX4747EUD and ADG1419BCPZ-REEL7, the MAX4747EBE uniquely balances ultra-low leakage (<0.1nA), sub-1nW power, and 2mm² footprint-making it irreplaceable in space- and energy-constrained portable medical and audio designs where alternative packages or higher leakage would compromise core functionality.

FAQ
What is the maximum supply voltage for MAX4747EBE?
The MAX4747EBE supports a supply voltage range of +2V to +11V, with an absolute maximum rating of +12V referenced to GND. Operation at +11V is permitted but requires a minimum 0.1µF bypass capacitor placed close to the V+ pin to ensure stability and prevent latch-up under transient conditions.
Does MAX4747EBE support rail-to-rail analog signals?
Yes, the MAX4747EBE handles analog signals from GND to V+ without clipping or distortion. This rail-to-rail capability is guaranteed across its full supply range (+2V to +11V) and enables direct interfacing with unbuffered sensors and DACs without external level-shifting circuitry.
What is the on-resistance matching specification for MAX4747EBE at +3V?
At +3V supply, the MAX4747EBE guarantees on-resistance matching of ≤3.5Ω between channels (ΔRON = RON(MAX) − RON(MIN)). This tight matching is critical for applications like differential signal routing and multi-channel data acquisition where gain consistency is required.
Can MAX4747EBE be used in battery-powered glucose meters?
Yes, the MAX4747EBE is explicitly suited for glucose meters due to its <0.1nA leakage current at +25°C, 0.5nW typical quiescent power, and rail-to-rail operation-key attributes for preserving accuracy and extending battery life in high-impedance electrochemical sensor front-ends.
What package type does MAX4747EBE use, and what are its dimensions?
The MAX4747EBE uses a 16-bump UCSP (Ultra Compact Silicon Package) with exact dimensions of 2.0mm × 2.0mm. This wafer-level chip-scale package occupies minimal PCB area and is optimized for automated reflow assembly in high-density portable electronics.
