Product details
Overview
MAX4595EXK-T from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST) CMOS analog switch operating from a single +2.0V to +5.5V supply, delivering 10Ω max on-resistance, 1.5Ω max on-resistance flatness at +5V, and <40ns switching times. It is used in audio signal routing paths within battery-powered cellular handsets where low leakage (0.5nA max off-leakage) and minimal charge injection (5pC max) preserve signal integrity.
For engineers reviewing the MAX4595EXK-T datasheet, MAX4595EXK-T pinout, MAX4595EXK-T application, or MAX4595EXK-T equivalent, key selection criteria include NC logic behavior, SC70-5 package compatibility, guaranteed -80dB off-isolation at 1MHz, 300MHz -3dB bandwidth, and TTL/CMOS logic compatibility for seamless integration into low-voltage portable designs.
Technical Context
The MAX4595EXK-T implements a bidirectional SPST analog switch with NC default state: logic low at IN connects COM to NC, while logic high opens the path. Its CMOS architecture enables rail-to-rail analog signal handling (GND to V+) with minimal RON variation across voltage and temperature.
It features integrated protection against overvoltage transients via internal clamping diodes, supports single-supply operation without level-shifting, and maintains 0.05% THD across 20Hz–20kHz with 600Ω load-critical for high-fidelity audio switching in space-constrained mobile platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at +5V - ensures minimal voltage drop and power loss in signal paths up to 10mA. |
| RON Flatness | 1.5Ω max over full analog range - preserves linearity and gain accuracy in precision audio/video routing. |
| Off-Isolation | -80dB at 1MHz - suppresses crosstalk between inactive channels in multi-signal systems like DSL modems. |
| Charge Injection | 5pC max - limits glitch-induced DC offset in sample-and-hold or ADC front-end applications. |
| Bandwidth (-3dB) | 300MHz at +25°C - supports high-speed video (e.g., VGA, SDI) and broadband communications signals. |
| Supply Range | +2.0V to +5.5V - enables direct interface with Li-ion battery (3.0–4.2V) and 3.3V/5V logic domains. |
| Leakage Current | 0.5nA max off-leakage - prevents battery drain in always-on standby circuits of portable equipment. |
Pinout & Package
MAX4595EXK-T is housed in a 5-pin SC70-5 package (1.6mm × 1.6mm × 0.95mm), optimized for ultra-compact PCB layouts in handheld devices. The exposed pad is absent-this variant uses standard SC70, not µDFN.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | Normally closed analog terminal - connected to COM when IN = LOW; bidirectional signal path. |
| 2 | IN | Digital control input - TTL/CMOS compatible; LOW enables NC-COM connection, HIGH disconnects. |
| 3 | GND | Analog and digital ground reference - must be low-impedance for noise-sensitive analog performance. |
| 4 | COM | Common analog terminal - serves as shared I/O node between NC and signal source/load. |
| 5 | V+ | Positive supply - powers internal switch core and logic; must be stable ±5% for specified RON and timing. |
Key Features
| Feature | Design Value |
|---|---|
| NC Default State | Ensures fail-safe signal continuity during power-up or logic fault-critical for safety-critical audio mute paths. |
| Ultra-Low Charge Injection | 5pC max eliminates visible stepping artifacts in video DAC output switching and reduces calibration overhead. |
| Bidirectional Signal Flow | NO/NC/COM pins are functionally identical-enables flexible layout routing without directionality constraints. |
| SC70-5 Footprint | 1.6mm × 1.6mm size saves >60% board area vs. SO-8, supporting miniaturized smartphone camera modules. |
| Single-Supply Simplicity | Eliminates need for dual-rail supplies or level shifters-reduces BOM count and power domain complexity. |
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 |
|---|---|---|---|
| MAX4595ELT-T | Same electrical specs, but in 6-pin µDFN (1.5mm × 1.0mm) with exposed thermal pad. | Higher power dissipation capability and improved thermal performance in dense layouts. | Select for thermally demanding applications requiring >168mW continuous dissipation at +70°C ambient. |
| ADG849BRMZ-REEL7 | NC SPST switch with 0.5Ω typical RON, but higher 10nA max off-leakage and +1.8V to +5.5V supply range. | Better RON for precision instrumentation, but insufficient for ultra-low-leakage medical sensing. | Prefer when lowest on-resistance dominates design priority and leakage tolerance exceeds 1nA. |
Compared with MAX4595EXK-T, the MAX4595ELT-T offers superior thermal management in compact spaces, while the ADG849BRMZ-REEL7 trades leakage performance for lower conduction loss-making MAX4595EXK-T optimal for battery-critical, low-noise portable audio and sensor front-ends.

FAQ
What is the default switch state of the MAX4595EXK-T?
The MAX4595EXK-T is a normally closed (NC) analog switch: when the IN pin is logic low (≤0.8V), the NC and COM terminals are connected; when IN is logic high (≥2.4V at +5V supply), the path opens. This fail-safe behavior ensures signal continuity during power-up or control loss, making MAX4595EXK-T ideal for audio mute paths and safety-critical analog routing where default conduction is required.
Does the MAX4595EXK-T support rail-to-rail analog signal operation?
Yes, the MAX4595EXK-T supports rail-to-rail analog signal operation from GND to V+, with on-resistance varying less than 1.5Ω across the full range at +5V supply. This allows undistorted switching of signals such as audio waveforms, sensor outputs, and video sync pulses without clipping or compression-confirmed by the "On-Resistance vs. COM Voltage" curves in the datasheet for MAX4595EXK-T across -40°C to +85°C.
What is the maximum allowable supply voltage for the MAX4595EXK-T?
The absolute maximum supply voltage for MAX4595EXK-T is +6V, but the recommended operating range is +2.0V to +5.5V. Operation above +5.5V risks permanent damage per Absolute Maximum Ratings. At +5.5V, parameters like RON (12Ω max), leakage (<0.5nA), and switching speed remain within spec-however, sustained use near 6V degrades reliability and is not guaranteed.
Can the MAX4595EXK-T be used in bidirectional signal paths?
Yes, the MAX4595EXK-T is fully bidirectional: signals pass equally well from NC to COM or COM to NC, with identical RON, bandwidth, and THD in both directions. This is explicitly stated in the Pin Description section ("NO, NC, and COM pins are identical and interchangeable") and verified by symmetric test conditions in the Electrical Characteristics tables for MAX4595EXK-T-enabling flexible PCB routing and reuse across transmit/receive paths.
Is the SC70-5 package of the MAX4595EXK-T lead-free and RoHS-compliant?
Yes, the MAX4595EXK-T SC70-5 package is lead-free and RoHS-compliant, as confirmed by Maxim's official packaging documentation (Package Outline 21-0076) and material declarations. The top mark "AAI" corresponds to the -40°C to +85°C temperature grade in green (halogen-free) SC70 packaging, meeting JEDEC J-STD-020 moisture sensitivity level 1 requirements for MAX4595EXK-T.
