Product details
Overview
MAX4719EUB+ from Maxim Integrated is a dual single-pole/double-throw (SPDT) analog switch IC operating from +1.8V to +5.5V, featuring 20Ω max on-resistance, <80ns turn-on time at +2.7V, and 300MHz -3dB bandwidth. It enables high-fidelity audio/video signal routing in space-constrained portable devices such as smartphones and PDAs.
For engineers reviewing the MAX4719EUB+ datasheet, MAX4719EUB+ pinout, MAX4719EUB+ application, or MAX4719EUB+ equivalent, key selection criteria include rail-to-rail signal handling, 0.4Ω RON match between channels, break-before-make timing (1ns), and UCSP package compatibility with fine-pitch PCB assembly.
Technical Context
The MAX4719EUB+ implements two independent SPDT switches using BiCMOS process technology, supporting bidirectional analog signal flow across COM/NO/NC terminals. Its break-before-make architecture prevents momentary shorting during channel switching, with tBBM = 1ns guaranteed over temperature.
Logic inputs accept +1.8V CMOS-compatible levels (VIL = 0.5V, VIH = 1.4V at +3V supply) and tolerate up to +5.5V regardless of V+, enabling mixed-voltage system interfacing. Signal range extends rail-to-rail (0V to V+), and leakage remains below ±1nA at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 20Ω max at +2.7V - ensures minimal voltage drop and power loss in low-voltage signal paths |
| RON match | 0.4Ω max at +3.0V - maintains consistent gain/attenuation across dual channels for balanced signal routing |
| Bandwidth (-3dB) | 300MHz - supports high-speed video, USB 1.1, and wideband audio without attenuation |
| Turn-on time (tON) | <80ns at +2.7V - enables fast multiplexing in data acquisition and sample-and-hold systems |
| Off-isolation | -55dB at 10MHz - suppresses crosstalk between active and inactive signal paths |
| Charge injection | 18pC - limits voltage glitch on sampled nodes in precision ADC front-ends |
| Supply current | 1µA max - supports ultra-low-power battery operation in always-on signal monitoring |
Pinout & Package
The MAX4719EUB+ is supplied in a 12-bump UCSP (Ultra-Compact Silicon Package) measuring 2.0mm × 1.50mm with 0.5mm bump pitch, optimized for minimal PCB footprint in mobile applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Accept +1.8V logic; drive internal switch gates - polarity determines NO/NC connection state |
| COM1, COM2 | Common analog terminals | Bidirectional signal path hub - connects to either NO or NC based on IN logic state |
| NO1, NO2 | Normally open analog terminals | Signal path closed only when corresponding IN = high - used for default-open routing |
| NC1, NC2 | Normally closed analog terminals | Signal path closed only when corresponding IN = low - enables inverted logic control |
| V+ | Positive supply | +1.8V to +5.5V single supply - powers analog core and logic interface |
| GND | Ground reference | Analog and digital return - must be low-impedance to minimize THD and noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports full 0V to V+ analog swing without clipping - essential for dynamic-range-critical audio and sensor interfaces |
| Break-before-make switching | 1ns guaranteed delay prevents signal shorting during channel transitions - critical for protecting downstream amplifiers and ADCs |
| Low on-capacitance (20pF) | Minimizes loading on high-impedance sources and preserves bandwidth in RF and video paths |
| High off-isolation (-55dB @10MHz) | Ensures >99.7% signal rejection between disconnected channels - vital for multi-source A/V routing |
| 0.03% THD | Maintains signal fidelity in audio applications without audible distortion or harmonic artifacts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4679EUB+ | Same UCSP-12 package, but 35Ω RON max and 100MHz bandwidth - higher on-resistance and lower speed | Lower bandwidth limits use in video or high-sample-rate DAQ; suitable for cost-sensitive audio-only routing | Select MAX4679EUB+ only if 300MHz bandwidth and 20Ω RON are not required |
| ADG732BRUZ | 16-channel SPST (not SPDT), TSSOP-24 package, 4Ω RON, 200MHz bandwidth - different topology and larger footprint | Requires external logic for SPDT emulation; better for high-channel-count, low-RON systems where board area is less constrained | Choose ADG732BRUZ when expanding beyond dual SPDT or requiring sub-5Ω RON at expense of layout complexity |
Compared with MAX4719EUB+, MAX4679EUB+ trades bandwidth and on-resistance for lower cost, while ADG732BRUZ offers higher channel count and lower RON in a larger package - neither is pin-compatible, and both require schematic and layout revision.

FAQ
What is the maximum supply voltage rating for MAX4719EUB+?
The MAX4719EUB+ supports a single-supply range of +1.8V to +5.5V. Absolute maximum V+ is +6.0V, but operation above +5.5V is not guaranteed and may compromise reliability or parametric performance. The device is fully specified and characterized from +2.7V to +3.6V and +4.2V to +5.5V, with typical performance validated at +3.0V and +5.0V.
Does MAX4719EUB+ support rail-to-rail analog signal operation?
Yes, MAX4719EUB+ supports true rail-to-rail analog signal handling - the analog input/output range extends from GND (0V) to V+ across the full operating temperature range. This allows full utilization of the supply voltage for maximum dynamic range in audio, sensor, and data-acquisition applications without signal clipping.
What is the function of the NC1 and NC2 pins on MAX4719EUB+?
NC1 and NC2 are the normally closed analog terminals for Switch 1 and Switch 2 respectively. When the corresponding digital control input (IN1 or IN2) is logic low, the COM–NC path is closed; when IN is high, the COM–NO path closes instead. This dual-throw configuration provides flexible signal routing options, including inverted logic control for system-level timing synchronization.
Can MAX4719EUB+ be used with a 1.8V logic supply while operating from a 3.3V analog supply?
Yes, MAX4719EUB+ logic inputs are +1.8V CMOS-compatible and tolerate up to +5.5V regardless of V+. With V+ = +3.3V, IN1/IN2 can be driven by a separate +1.8V logic source - VIH = +1.4V min and VIL = +0.5V max ensure reliable switching without level-shifting circuitry, simplifying mixed-voltage system design.
Is the UCSP package of MAX4719EUB+ compatible with standard reflow soldering processes?
The MAX4719EUB+ UCSP package requires adherence to JEDEC J-STD-020A profile (IR/VPR/convection), with preheating and strict bump temperature limits (220°C infrared, 215°C vapor phase). Hand or wave soldering is prohibited. Board layout must follow Maxim's UCSP guidelines to ensure solder joint integrity and mechanical reliability under thermal cycling.
