Product details
Overview
MAX4596EXK-T from Maxim Integrated is a normally open (NO), single-pole/single-throw (SPST) CMOS analog switch optimized for high off-isolation in SC70-5 packaging. It operates from a single +2.0V to +5.5V supply, delivers ≤10Ω on-resistance and ≤1.5Ω on-resistance flatness at +5V, and supports fast switching (tON ≤ 35ns, tOFF ≤ 40ns) for audio/video signal routing in battery-powered handheld devices.
For engineers reviewing the MAX4596EXK-T datasheet, MAX4596EXK-T pinout, MAX4596EXK-T application, or MAX4596EXK-T equivalent, key selection criteria include its 5-pin SC70 package, NO logic behavior, guaranteed ≤5pC charge injection, -80dB off-isolation at 1MHz, and bidirectional analog signal handling across the full rail-to-rail range.
Technical Context
The MAX4596EXK-T implements a low-voltage, single-supply SPST switch architecture with CMOS transmission-gate topology. Its control logic is TTL/CMOS-compatible, with VIH = +2.4V (min) and VIL = +0.8V (max) at +5V supply, enabling direct interfacing with microcontrollers and baseband processors without level-shifting.
It features rail-to-rail analog signal capability (VCOM, VNO, VNC = GND to V+), bidirectional signal flow, and guaranteed performance over -40°C to +85°C. The device achieves 300MHz -3dB bandwidth at +25°C and maintains ≤0.05% THD in 600Ω audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration into 3.3V and 5V systems without auxiliary rails |
| On-Resistance (RON) | ≤10Ω max at +5V - minimizes voltage drop and power loss in precision signal paths |
| On-Resistance Flatness | ≤1.5Ω max over signal range - ensures consistent gain and linearity in audio and sensor interfaces |
| Charge Injection | ≤5pC max - reduces glitch-induced settling errors in sample-and-hold and multiplexer applications |
| Off-Isolation | -80dB at 1MHz - suppresses crosstalk between inactive channels in multi-signal routing |
| Switching Time | tON ≤ 35ns, tOFF ≤ 40ns - supports high-speed data and video switching up to ~10MHz digital rates |
| Leakage Current | ≤0.5nA max off-leakage - preserves battery life and signal integrity in ultra-low-power standby modes |
Pinout & Package
MAX4596EXK-T is packaged in a 5-pin SC70 (SC70-5) surface-mount package measuring 2.0mm × 1.25mm × 0.95mm, with an exposed pad not present (µDFN variant has EP; SC70 does not). Pin 1 is marked by a dot or beveled edge.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM | Common analog terminal - bidirectional I/O node connected to load or source in SPST configuration |
| 2 | NO | Normally open analog terminal - connects to COM only when IN is HIGH; floating when OFF |
| 3 | GND | Ground reference - must be low-impedance connection to minimize noise coupling and ensure logic threshold stability |
| 4 | IN | Digital control input - TTL/CMOS-compatible; drives internal gate to enable/disable NO–COM path |
| 5 | V+ | Positive supply - powers analog switch core and logic interface; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports signals from GND to V+ - eliminates need for external biasing in DC-coupled audio/video paths |
| Bidirectional signal flow | NO, NC, and COM pins are functionally interchangeable - simplifies PCB layout and enables flexible signal routing |
| Ultra-low charge injection | ≤5pC max - prevents output voltage glitches during switching in precision sampling circuits |
| High off-isolation | -80dB at 1MHz - isolates unused signal paths to prevent interference in multi-channel communication systems |
| Low THD+N | 0.05% at 20Hz–20kHz - preserves fidelity in portable audio codecs and headset switching applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4596ELT-T | Same electrical specs; 6-pin µDFN-6 package (1.5mm × 1.0mm) with exposed pad | Higher thermal dissipation and slightly better high-frequency performance due to lower parasitic inductance | Select for designs requiring improved thermal management or tighter layout constraints where µDFN is preferred |
| ADG801BRMZ | 1.8V–5.5V supply; 0.5Ω typical RON but higher 10pC charge injection; 6-pin SOT-23 | Lower on-resistance suits precision instrumentation; higher charge injection limits use in fast-sampling systems | Select when ultra-low RON outweighs charge injection sensitivity; not drop-in due to different pinout and package |
Compared with MAX4596EXK-T, the MAX4596ELT-T offers identical functionality in a thermally enhanced µDFN package, while the ADG801BRMZ trades lower on-resistance for higher charge injection and requires PCB redesign - making MAX4596EXK-T optimal for space-constrained, low-glitch audio and telecom routing.

FAQ
What is the logic behavior of the MAX4596EXK-T?
The MAX4596EXK-T is a normally open (NO) SPST analog switch: the COM–NO path is open (high impedance) when the IN pin is logic LOW, and closed (low RON) when IN is logic HIGH. This matches the truth table in the MAX4594–MAX4597 datasheet, where MAX4596/MAX4594 are NO variants. The MAX4596EXK-T does not have an NC pin - pin 5 is V+, and pin 2 is NO.
Does the MAX4596EXK-T support rail-to-rail analog signals?
Yes, the MAX4596EXK-T supports analog signals from GND to V+ across its COM and NO terminals, with minimal variation in on-resistance over that full range. At +5V supply, RON flatness is guaranteed ≤1.5Ω, and the device maintains this performance from -40°C to +85°C. This rail-to-rail capability allows direct interfacing with op-amps, ADCs, and DACs without level-shifting circuitry.
What is the maximum operating temperature range for the MAX4596EXK-T?
The MAX4596EXK-T is rated for operation from -40°C to +85°C, as confirmed in the Ordering Information table of the datasheet. All electrical specifications - including RON, leakage current, switching time, and off-isolation - are guaranteed across this full industrial temperature range, making it suitable for automotive infotainment front-end modules and outdoor telecom equipment.
Can the MAX4596EXK-T be used with a 3.3V supply?
Yes, the MAX4596EXK-T operates reliably from +2.7V to +3.6V per its +3V supply characterization. At +3.3V, typical on-resistance is ~20Ω (max 25Ω), tON/tOFF remain under 55ns, and logic thresholds scale accordingly (VIH ≥ +2.0V, VIL ≤ +0.8V). This makes the MAX4596EXK-T fully compatible with standard 3.3V microcontroller GPIOs and LDO-regulated systems.
Is the MAX4596EXK-T pin-compatible with other parts in the MAX4594–MAX4597 family?
Within the SC70-5 variants, the MAX4596EXK-T shares identical pinout with MAX4594EXK-T, MAX4595EXK-T, and MAX4597EXK-T - all use the same 5-pin SC70 layout with COM, NO/NC, GND, IN, and V+. However, logic behavior differs: MAX4596EXK-T and MAX4594EXK-T are NO, while MAX4595EXK-T and MAX4597EXK-T are NC. Swapping NO/NC types requires firmware or schematic changes.
