Product details
Overview
The MAX4599EUT+T from Maxim Integrated is a single-pole/double-throw (SPDT) analog switch operating from a +2.0V to +5.5V single supply, featuring 60Ω max on-resistance at +5V, 30ns max turn-on time, 25ns max turn-off time, and 5pC max charge injection. It serves as a low-voltage signal routing device in portable audio paths and battery-powered data acquisition systems.
For engineers reviewing the MAX4599EUT+T datasheet, MAX4599EUT+T pinout, MAX4599EUT+T application, or MAX4599EUT+T equivalent, key selection criteria include on-resistance flatness (4Ω max), RON matching (1Ω max), break-before-make timing (10ns typ), -76dB off-isolation at 1MHz, and SC70/SOT23/μDFN package compatibility.
Technical Context
This SPDT switch uses CMOS process technology with TTL/CMOS-compatible digital control and bidirectional analog signal handling across the full 0V to V+ range. Its internal architecture ensures break-before-make switching to prevent signal shorting during state transitions.
It delivers 200MHz -3dB bandwidth and 0.12% THD for high-fidelity audio routing, while maintaining ±0.5nA leakage current at +25°C and guaranteed 5pC max charge injection for precision sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration into 2.5V, 3.3V, and 5V logic and analog systems without level shifting. |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-level sensor or audio signal paths. |
| RON Matching | 1Ω max between channels - critical for matched gain paths in differential or dual-channel routing applications. |
| Charge Injection | 5pC max - limits voltage glitch on sampled nodes, supporting accurate DC-coupled acquisition in precision ADC front-ends. |
| Off-Isolation | -76dB at 1MHz - suppresses crosstalk between inactive signal paths in multi-source audio/video routing. |
| Bandwidth | 200MHz -3dB - supports composite video, USB 1.1, and baseband RF signal switching without roll-off. |
| Leakage Current | ±0.5nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and battery-monitoring circuits. |
Pinout & Package
The MAX4599EUT+T is supplied in a 6-pin SOT23-6 package (top mark AAHC), with 1.5mm × 2.9mm footprint, 0.95mm height, and standard JEDEC MO-178AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | TTL/CMOS-compatible logic input that selects NO or NC path; active-high logic sense per truth table. |
| 2 - V+ | Positive supply rail | Single power connection for analog and digital sections; must be applied before analog signals to avoid latch-up. |
| 3 - GND | Analog/digital ground reference | Common return for supply, logic, and analog paths; requires low-impedance PCB connection to minimize noise coupling. |
| 4 - N.C. | Normally closed analog terminal | Connects to COM when IN = 0; used for default-path routing in fail-safe or power-loss scenarios. |
| 5 - COM | Common analog terminal | Bidirectional signal port - accepts input or delivers output depending on system topology; rated for ±20mA continuous current. |
| 6 - NO | Normally open analog terminal | Connects to COM when IN = 1; provides alternate signal path with identical RON and capacitance specs as N.C. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 10ns minimum interval prevents momentary shorting between NO and NC paths during transition. |
| RON flatness | 4Ω max variation over full 0V–V+ analog range - maintains consistent gain and linearity across signal swing. |
| Low charge injection | 5pC max - reduces settling error in multiplexed ADC inputs and sample-and-hold hold capacitors. |
| High off-isolation | -76dB at 1MHz - isolates unused audio/video sources to prevent audible hum or ghosting in consumer equipment. |
| Wide supply range | +2.0V to +5.5V operation - supports direct interface with Li-ion battery (3.0–4.2V), 3.3V MCU I/O, and legacy 5V peripherals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4699EUT+T | Same pinout, 35Ω max RON at +5V, 20ns faster tON/tOFF, but higher 10pC charge injection. | Better speed and lower RON, but less suitable for ultra-low-glitch sample-and-hold. | Select when bandwidth >250MHz and RON <40Ω are prioritized over charge injection. |
| TMUX1574DSGR | 4.5V max supply, 4.5Ω typical RON, 1.5pC charge injection, but only -40°C to +125°C temp range. | Superior THD (0.003%) and lower leakage, but incompatible with 5V systems. | Choose for high-precision industrial DAQ where 5V operation is not required and extended temperature is needed. |
Compared with MAX4599EUT+T, MAX4699EUT+T trades lower charge injection for higher speed and lower RON, while TMUX1574DSGR offers superior linearity and leakage performance at the cost of 5V incompatibility - making MAX4599EUT+T optimal for balanced 2.0–5.5V portable designs requiring robustness and proven reliability.

FAQ
What is the maximum supply voltage rating for the MAX4599EUT+T?
The MAX4599EUT+T has an absolute maximum supply voltage (V+) of +6V, but its specified operational range is +2.0V to +5.5V. Exceeding +5.5V may cause parametric degradation or permanent damage, and operation above +6V violates absolute maximum ratings. The MAX4599EUT+T must be powered within this window to guarantee 60Ω max RON, 30ns tON, and all other published specifications.
Does the MAX4599EUT+T support bidirectional analog signal flow?
Yes, the MAX4599EUT+T supports fully bidirectional analog signal routing between COM, NO, and N.C. terminals. Its CMOS-based switch architecture imposes no directionality constraint - voltage or current can flow from COM to NO, NO to COM, COM to N.C., or N.C. to COM with identical RON, capacitance, and leakage characteristics. This makes the MAX4599EUT+T suitable for both input multiplexing and output demultiplexing in audio and sensor interfaces.
What is the guaranteed charge injection specification for the MAX4599EUT+T?
The MAX4599EUT+T guarantees a maximum charge injection of 5pC under standard test conditions (VGEN = 0, RGEN = 0, CL = 1.0nF). This value is tested and specified across the full -40°C to +85°C temperature range. Charge injection directly impacts hold-step accuracy in sample-and-hold circuits; the 5pC limit ensures <1mV glitch on a 5nF hold capacitor, making the MAX4599EUT+T appropriate for 12-bit precision data acquisition systems.
Is the MAX4599EUT+T pin-compatible with other variants in the MAX4599 family?
Yes, the MAX4599EUT+T shares identical pin configuration and function with MAX4599EXT+T (SC70-6) and MAX4599ELT+T (μDFN-6): Pin 1 = IN, Pin 2 = V+, Pin 3 = GND, Pin 4 = N.C., Pin 5 = COM, Pin 6 = NO. All three variants use the same truth table and electrical behavior, enabling direct PCB footprint substitution when thermal or board-space constraints dictate package change - though thermal derating differs per package (SOT23-6 = 571mW, μDFN-6 = 168mW, SC70-6 = 245mW).
What is the off-isolation performance of the MAX4599EUT+T at 1MHz?
The MAX4599EUT+T provides -76dB off-isolation at 1MHz, measured with 5pF load capacitance and 50Ω source impedance. This specification reflects suppression of signal coupling from an energized NO or N.C. path into the disconnected COM terminal. At higher frequencies, isolation degrades gradually - e.g., -55dB at 10MHz - but the -76dB value ensures negligible crosstalk in voice-band and baseband video applications, directly supporting clean audio routing in cellular phones and portable media players using the MAX4599EUT+T.
