Product details
Overview
MAX4717EUB/GH9 from Maxim Integrated is a dual SPDT analog switch with two 4.5Ω (max) low-RON channels, rail-to-rail signal handling, and <80ns turn-on time at +2.7V - designed for USB 1.1 D+/D− switching and headphone routing in portable audio systems.
For engineers reviewing the MAX4717EUB/GH9 datasheet, MAX4717EUB/GH9 pinout, MAX4717EUB/GH9 application, or MAX4717EUB/GH9 equivalent, key selection criteria include guaranteed 0.3Ω RON match (+3.0V), 300MHz bandwidth, 15pF on-capacitance, break-before-make timing (1ns), and UCSP-12 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4717EUB/GH9 implements dual independent SPDT switches using BiCMOS process technology, supporting single-supply operation from +1.8V to +5.5V with +1.8V logic-compatible digital inputs. Each channel delivers matched on-resistance flatness (≤1.2Ω) and differential skew ≤2ns - critical for maintaining USB 1.1 signal integrity.
Its UCSP-12 package features a 4×3 bump array (0.5mm pitch) occupying only 2.0mm × 1.50mm board area. The device guarantees break-before-make switching with tBBM ≤1ns, tON <80ns, and tOFF <40ns at +2.7V, enabling high-fidelity analog signal routing without crosstalk-induced distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 4.5Ω per SPDT channel - ensures minimal insertion loss (<0.1dB) for 600Ω audio and USB 1.1 D+/D− signals |
| RON match (max) | 0.3Ω at +3.0V - enables precise channel balancing in stereo headphone switching and differential data paths |
| Bandwidth (-3dB) | >300MHz - supports full-speed USB 1.1 (12Mbps) with <0.5% signal degradation |
| On-capacitance | 15pF - limits capacitive loading on high-speed lines, preserving rise/fall times in data acquisition |
| Off-isolation | -55dB at 10MHz - suppresses coupling between active and inactive signal paths in multi-source A/V routing |
| THD | 0.03% - maintains fidelity in 2VP-P audio signals across 600Ω loads |
| tON/tOFF | <80ns / <40ns at +2.7V - enables fast multiplexing in sample-and-hold and battery-powered instrumentation |
Pinout & Package
MAX4717EUB/GH9 is packaged in a 12-bump UCSP (chip-scale package) with 2.0mm × 1.50mm footprint and 0.5mm bump pitch. The package uses a 4×3 bump array and requires solder reflow per Maxim's UCSP profile (vapor phase: 215°C/60s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| NO1 | Analog Switch 1 - Normally Open Terminal | Connects to COM1 when IN1 = logic high; used for primary signal path selection in USB/audio routing |
| COM1 | Analog Switch 1 - Common Terminal | Central I/O node for Switch 1; bidirectional - accepts input or delivers output depending on system topology |
| NC1 | Analog Switch 1 - Normally Closed Terminal | Connects to COM1 when IN1 = logic low; provides default path for fail-safe or standby routing |
| IN1 | Analog Switch 1 - Digital Control Input | +1.8V logic compatible; drives Switch 1 independently of V+ (supports mixed-voltage control up to +5.5V) |
| NO2 | Analog Switch 2 - Normally Open Terminal | Independent second SPDT path; identical RON and timing specs to NO1 - enables stereo or dual-channel routing |
| COM2 | Analog Switch 2 - Common Terminal | Second bidirectional I/O node; electrically isolated from COM1 - prevents inter-channel interference |
| NC2 | Analog Switch 2 - Normally Closed Terminal | Default path for Switch 2; allows simultaneous configuration of two independent analog signal paths |
| IN2 | Analog Switch 2 - Digital Control Input | Independent logic input; enables asynchronous control of Switch 2 without affecting Switch 1 |
| V+ | Positive-Supply Voltage | Single supply input (1.8V–5.5V); powers both analog and digital sections - eliminates need for level shifters |
| GND | Ground Reference | Common return for analog signals and digital logic; must be low-impedance to maintain THD and isolation specs |
| Bump A1–C4 | UCSP Bump Array | 4×3 layout (A1–A4, B1–B4, C1–C4) - matches Maxim's standard UCSP-12 land pattern; no exposed pad |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 compliance (TID = 4000231) | Validated for D+/D− signal routing with ≤2ns differential skew and 12Mbps data integrity |
| Rail-to-rail signal handling | Supports analog voltages from GND to V+ - eliminates clipping in battery-operated audio front-ends |
| Break-before-make switching (1ns) | Prevents momentary short-circuits during state transitions - essential for protecting sensitive audio DACs and USB transceivers |
| Low 15pF on-channel capacitance | Minimizes high-frequency loading on 50Ω/600Ω sources - preserves signal edge rates in video and data acquisition |
| +1.8V CMOS logic compatibility | Accepts 0.5V/1.4V thresholds at +3V supply - enables direct interface with low-voltage microcontrollers and FPGAs |
| 0.03% THD at 2VP-P | Ensures transparent audio path in headphone amplifiers and line-level mixing without harmonic artifacts |

FAQ
What is the maximum supply voltage rating for MAX4717EUB/GH9?
The MAX4717EUB/GH9 has an absolute maximum supply voltage (V+) rating of +6.0V, but its specified operational range is +1.8V to +5.5V. Operating beyond +5.5V risks permanent damage, and functional performance is only guaranteed within the 1.8V–5.5V range per the datasheet's Electrical Characteristics tables.
Does MAX4717EUB/GH9 support rail-to-rail analog signal switching?
Yes, MAX4717EUB/GH9 supports rail-to-rail analog signal handling - its analog terminals (COM_, NO_, NC_) operate from GND to V+ across the full supply range. This allows undistorted switching of signals spanning the entire supply voltage, which is essential for audio line drivers and battery-powered sensor interfaces.
What is the guaranteed on-resistance matching between the two SPDT channels of MAX4717EUB/GH9?
The MAX4717EUB/GH9 guarantees ≤0.3Ω on-resistance match (∆RON) between its two SPDT channels at +3.0V supply and +25°C. This tight matching ensures balanced signal paths in stereo audio routing and differential USB applications where channel symmetry is critical.
Can MAX4717EUB/GH9 be used in USB 2.0 applications?
No, MAX4717EUB/GH9 is specifically characterized and certified for USB 1.1 (12Mbps) compliance (TID = 4000231). Its >300MHz bandwidth and ≤2ns skew meet USB 1.1 requirements, but it lacks the signal integrity margin and ESD robustness needed for USB 2.0's 480Mbps operation.
What is the thermal resistance (θJA) of the UCSP-12 package used in MAX4717EUB/GH9?
The UCSP-12 package for MAX4717EUB/GH9 has a thermal resistance of θJA = 87.7°C/W (calculated from 909mW max power dissipation at TA = +70°C with 11.4mW/°C derating). This value assumes standard JEDEC 2-layer board conditions; actual thermal performance depends on PCB copper area and via placement under the die.
