Product details
Overview
MAX4747EWE+T from Maxim Integrated is a low-voltage, quad SPST analog switch with four normally open (NO) channels in a 16-bump wafer-level package (WLP). It operates from +2V to +11V, delivers ≤50Ω on-resistance at +3V, ≤25Ω at +5V, 3.5Ω max on-resistance matching, <0.1nA leakage at +25°C, and rail-to-rail signal handling-ideal for space-constrained, battery-powered signal routing in portable medical and communications devices.
For engineers reviewing the MAX4747EWE+T datasheet, MAX4747EWE+T pinout, MAX4747EWE+T application, or MAX4747EWE+T equivalent, this page provides verified electrical specs, WLP bump mapping, real-world use cases in glucose meters and audio routing, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The MAX4747EWE+T implements CMOS-based bidirectional analog switching with TTL/CMOS-compatible digital control inputs. Its architecture guarantees rail-to-rail analog signal pass-through and supports single-supply operation without level-shifting circuitry.
It features guaranteed on-resistance flatness (≤9Ω at +3V), low charge injection (7pC), high off-isolation (−72dB at 1MHz), and crosstalk suppression (−84dB at 1MHz), enabling precision signal integrity in low-noise data-acquisition paths and audio channel selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +11V single supply - eliminates need for dual rails in portable systems |
| On-Resistance (RON) | ≤50Ω at +3V - ensures minimal signal attenuation in low-voltage sensor interfaces |
| On-Resistance Matching | ≤3.5Ω max between channels at +3V - critical for matched gain paths in multi-channel ADC front-ends |
| Leakage Current | <0.1nA at +25°C - preserves battery life and accuracy in high-impedance glucose meter electrode circuits |
| Off-Isolation | −72dB at 1MHz - prevents signal bleed between inactive audio/video channels |
| Crosstalk | −84dB at 1MHz - maintains channel separation in multi-source A/V routing |
| Turn-On/Off Time | 170ns / 70ns at +3V - supports fast multiplexing in real-time data acquisition |
Pinout & Package
MAX4747EWE+T uses a 2mm × 2mm, 16-bump wafer-level package (WLP) with bumps arranged in a 4×4 grid. The package is RoHS-compliant, lead-free, and optimized for minimal PCB area in ultra-compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1, A2, C4, D2 | NO1–NO4 | Normally open analog switch terminals - connect only when corresponding IN_ is HIGH |
| A1, A3, D4, D3 | COM1–COM4 | Common analog node per channel - bidirectional signal path shared with NOx |
| C1, A4, B4, D1 | IN1–IN4 | Digital control inputs - TTL/CMOS compatible; drive to V+ or GND for reliable switching |
| C3 | GND | Digital ground reference - must be connected to system ground plane for logic stability |
| B2 | V+ | Positive supply for analog and digital sections - requires local 0.1µF bypass capacitor |
| A2, A4, D1, D3 | N.C. | No internal connection - leave unconnected; no pull-up/down required |
Key Features
| Feature | Design Value |
|---|---|
| 2mm × 2mm WLP footprint | Reduces PCB area by >70% vs. TSSOP - enables miniaturized wearable and implantable device layouts |
| Rail-to-rail analog signal handling | Supports full 0V to V+ range without clipping - essential for direct interfacing with op-amps and sensors |
| Guaranteed RON flatness ≤9Ω | Ensures consistent gain across signal swing - improves linearity in precision instrumentation |
| Low quiescent power: 0.5nW typ | Extends battery life in always-on monitoring systems - e.g., continuous glucose meters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4747ETE+ | Same die, 16-pin TQFN-EP (4mm × 4mm) package - larger footprint, exposed pad requires thermal tie to V+ | Suitable for higher-power or thermally demanding PCB layouts where WLP reflow is not feasible | Select when board assembly process lacks WLP capability or thermal management favors QFN |
| ADG1419BCPZ-REEL7 | Quad SPST, 16-lead LFCSP (3mm × 3mm); RON = 1.3Ω @ +5V but requires ≥±5V dual supply or +12V single supply | Higher performance RON and bandwidth, but incompatible with sub-3V battery systems | Choose only if system operates ≥+5V and needs lower RON; not drop-in for 2–3V designs |
Compared with MAX4747ETE+ and ADG1419BCPZ-REEL7, the MAX4747EWE+T uniquely combines ultra-small WLP size, true 2V–3V operation, and sub-0.1nA leakage-making it irreplaceable in compact, low-voltage, long-battery-life applications where space and quiescent current are primary constraints.

FAQ
What is the maximum supply voltage rating for MAX4747EWE+T?
The MAX4747EWE+T has an absolute maximum V+ rating of +12V, but its recommended operating range is +2V to +11V. Operation near +11V requires a minimum 0.1µF bypass capacitor placed close to the V+ pin. Exceeding +12V risks permanent damage, and sustained operation above +11V is not specified in the datasheet. Always observe the absolute maximum ratings when designing with MAX4747EWE+T.
Does MAX4747EWE+T support rail-to-rail analog signal switching?
Yes, MAX4747EWE+T supports rail-to-rail analog signal switching - signals from 0V to V+ pass through the switch with minimal distortion and guaranteed on-resistance flatness. This is confirmed in the Electrical Characteristics table (analog signal range = 0 to V+) and Typical Operating Characteristics plots. The bidirectional nature allows COM_, NO_, and NC_ pins to serve as either input or output, making MAX4747EWE+T suitable for flexible signal-path architectures.
What is the on-resistance matching specification for MAX4747EWE+T at +3V?
At +3V supply, MAX4747EWE+T guarantees ≤3.5Ω maximum on-resistance matching (∆RON) between any two channels, measured under V+ = +2.7V, ICOM_ = 5mA, and VNO_ = +1.5V. This parameter is explicitly listed in the +3V Electrical Characteristics table and is critical for applications requiring matched gain or timing paths, such as multi-channel sensor interfaces or differential signal routing. The matching is guaranteed by design for WLP variants.
Can MAX4747EWE+T be used with a +2.5V supply?
Yes, MAX4747EWE+T is fully specified and functional at +2.5V. Its operational supply range is +2V to +11V, and typical on-resistance curves (Figure MAX4747–50-toc04) confirm stable RON behavior down to +2.5V across temperature. Logic inputs remain TTL/CMOS-compatible at this voltage when driven rail-to-rail (0V and +2.5V), and leakage remains below 0.1nA. System designers can confidently deploy MAX4747EWE+T in 2.5V battery-powered applications.
What is the thermal pad configuration for MAX4747EWE+T?
MAX4747EWE+T does not have an exposed thermal pad - it is a 16-bump wafer-level package (WLP) with no EP or thermal slug. Unlike the TQFN variant (MAX4747ETE+), which requires the exposed pad to be connected to V+, the WLP version relies on bump-level thermal conduction through solder joints to the PCB. No special thermal land pattern is needed beyond the standard WLP footprint defined in Maxim Application Note 1891 and package drawing W162D2+1.
