Product details
Overview
MAX4679EUE+T from Analog Devices is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, featuring guaranteed break-before-make switching, 1.6Ω max on-resistance (dual ±5V), 0.3Ω max on-resistance matching, and rail-to-rail signal handling - ideal for precision audio routing and automated test equipment signal path control.
For engineers reviewing the MAX4679EUE+T datasheet, MAX4679EUE+T pinout, MAX4679EUE+T application, or MAX4679EUE+T equivalent, this device delivers low distortion (<0.001% THD+N at 1kHz), high off-isolation (–65dB @1MHz), and fast switching (tON = 350ns max) in a compact 16-pin TSSOP package suitable for space-constrained mixed-signal PCBs.
Technical Context
The MAX4679EUE+T implements four independent CMOS SPST switches in a single die, with dedicated NO/NC topology per channel pair (CH1/CH4 = NO; CH2/CH3 = NC) and internal logic ensuring strict break-before-make timing (5ns guaranteed). Its dual-supply architecture (±2.7V to ±5.5V) supports true bipolar analog signal routing without level-shifting.
It features a separate logic supply input (VL = +2.7V to V+) enabling independent control of digital interface voltage, while maintaining full analog performance across temperature (–40°C to +85°C) and supply variations - critical for reed relay replacement in industrial data-acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.6Ω max at ±5V dual supply - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| On-Resistance Matching | 0.3Ω max between channels - enables matched gain/phase response in multi-channel instrumentation. |
| Break-Before-Make Delay | 5ns guaranteed - prevents momentary short-circuit during channel switching in sensitive signal chains. |
| Off-Isolation | –65dB @1MHz - suppresses crosstalk between inactive and active signal paths in dense routing. |
| –3dB Bandwidth | 66MHz (dual supply) - supports high-fidelity audio and baseband video signal switching without roll-off. |
| Charge Injection | 85pC max - minimizes glitch-induced DC offset in sampled-data systems like ADC front-ends. |
| Supply Range | Single: +2.7V to +11V; Dual: ±2.7V to ±5.5V - enables flexible integration into both unipolar and bipolar systems. |
Pinout & Package
MAX4679EUE+T is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, thermal pad optional, and RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1, IN2, IN3, IN4 | CMOS/TTL-compatible logic inputs controlling respective switch states (active-high). |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal path connection points for all switches. |
| 3, 6 | NO1, NO4 | Normally open analog terminals - connect to COM only when corresponding IN = logic high. |
| 11, 14 | NC2, NC3 | Normally closed analog terminals - connect to COM when corresponding IN = logic low. |
| 4 | V− | Negative supply rail; tied to GND for single-supply operation. |
| 5 | GND | Analog/digital ground reference - must be low-impedance for leakage-sensitive applications. |
| 12 | VL | Independent logic supply input (2.7V to V+) - decouples digital control from analog supply noise. |
| 13 | V+ | Positive supply rail - sets upper limit of rail-to-rail analog signal range. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | 5ns minimum delay prevents signal shorting during channel transitions in multiplexer designs. |
| Rail-to-rail analog signal range | Supports full V− to V+ swing - eliminates need for external level shifters in ±5V systems. |
| Low on-resistance flatness | 0.4Ω max variation over signal range - maintains consistent gain and linearity across input amplitude. |
| TTL/CMOS logic compatibility | VIH = 2.4V, VIL = 0.8V at VL = V+ - ensures reliable interfacing with standard microcontrollers and FPGAs. |
| Ultra-low off-leakage current | 0.1nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4678EUE+T | Four NO-only channels; no NC functionality or break-before-make guarantee. | Suitable only where all paths require normally open behavior - not interchangeable for mixed NO/NC topologies. | Select when full NO configuration suffices and guaranteed break-before-make is unnecessary. |
| ADG1419BRUZ | Single-pole double-throw (SPDT) with 1.3Ω RON; requires two devices to match quad SPST count. | Higher board area and routing complexity; lacks integrated NO/NC pairing and break-before-make timing control. | Choose for higher channel density per package or when SPDT topology better fits system architecture. |
Compared with MAX4679EUE+T, MAX4678EUE+T offers identical package and drive compatibility but omits NC channels and break-before-make assurance, while ADG1419BRUZ provides lower RON but demands additional layout effort and discrete timing management to replicate safe switching behavior.

FAQ
What is the maximum supply voltage rating for MAX4679EUE+T?
The absolute maximum ratings specify V+ to GND = –0.3V to +12V and V− to GND = +0.3V to –12V, with V+ to V− limited to +12V. For reliable operation, Analog Devices recommends staying within the specified operating range: dual supplies of ±2.7V to ±5.5V or single supply of +2.7V to +11V. Exceeding these limits risks permanent damage to the MAX4679EUE+T.
Does MAX4679EUE+T support single-supply operation?
Yes, MAX4679EUE+T fully supports single-supply operation from +2.7V to +11V. In this mode, V− is connected to GND, and the analog signal range extends from 0V to V+. The device maintains key specs including 2.7Ω max RON (at +4.5V), –65dB off-isolation, and 63MHz –3dB bandwidth - making MAX4679EUE+T suitable for portable and cost-sensitive unipolar systems.
How does the break-before-make feature work in MAX4679EUE+T?
MAX4679EUE+T guarantees a minimum 5ns break interval between opening one switch and closing another within its NO/NC pairs (CH1/CH4 and CH2/CH3). This timing is internally controlled and independent of external logic slew rate or supply voltage. It prevents transient shorts during signal path reconfiguration - a critical safety feature in MAX4679EUE+T for protecting downstream circuitry in audio and measurement applications.
What is the logic supply voltage range for VL on MAX4679EUE+T?
The VL pin on MAX4679EUE+T accepts +2.7V to V+, allowing independent scaling of the logic interface voltage. When V+ = +5V, VL may be set to +3.3V for compatibility with modern microcontrollers, while preserving full analog performance. VIH remains 2.4V and VIL stays 0.8V regardless of VL setting - ensuring robust noise margins across the supported range for MAX4679EUE+T.
Can MAX4679EUE+T handle bipolar analog signals?
Yes, MAX4679EUE+T is explicitly designed for bipolar operation: with dual ±5V supplies, it passes rail-to-rail analog signals from V− (–5V) to V+ (+5V) without clipping or distortion. Its CMOS process and symmetric architecture ensure low THD+N and matched RON across the full range - a core capability confirmed in the MAX4679EUE+T datasheet's "Analog Switch" electrical characteristics section.
