Product details
Overview
MAX4597EXK+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, featuring 10Ω max on-resistance, 1.5Ω max RON flatness at +5V, and <40ns switching times. It is designed for low-voltage signal routing in battery-powered audio/video paths and communications interfaces.
For engineers reviewing the MAX4597EXK+T datasheet, MAX4597EXK+T pinout, MAX4597EXK+T application, or MAX4597EXK+T equivalent, key selection criteria include NC default state, SC70-5 package footprint, guaranteed ≤5pC charge injection, -80dB off-isolation at 1MHz, and bidirectional analog signal handling across full rail-to-rail range.
Technical Context
The MAX4597EXK+T implements a complementary MOSFET transmission gate architecture with matched P/N channel devices to achieve low and flat on-resistance over the entire analog signal range (GND to V+). Its logic input is TTL/CMOS-compatible with VIH = +2.4V (min) and VIL = +0.8V (max) when powered from +5V.
As a normally closed switch, it conducts by default and opens only when IN is driven high; this behavior is defined by internal transistor topology-not external biasing. The device maintains ≤0.5nA off-leakage and 0.05% THD across 20Hz–20kHz, supporting high-fidelity signal integrity in portable audio systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at +5V supply - ensures minimal voltage drop and power loss in signal path |
| RON Flatness | 1.5Ω max over full analog range - preserves linearity and gain accuracy in precision routing |
| Switching Time (tON/tOFF) | 35ns/40ns max - supports fast multiplexing in digital audio and data acquisition |
| Charge Injection | 5pC max - limits glitch-induced error in sample-and-hold or ADC front-end circuits |
| Off-Isolation | -80dB at 1MHz - suppresses crosstalk between adjacent channels in multi-signal systems |
| Analog Bandwidth | 300MHz -3dB at +25°C - enables clean pass-through of video and high-speed serial signals |
| Supply Range | +2.0V to +5.5V single supply - simplifies power design in mixed-voltage portable platforms |
Pinout & Package
MAX4597EXK+T is packaged in a 5-pin SC70-5 surface-mount package (top mark: AAK), with 1.3mm × 0.8mm footprint and 0.65mm pitch. The exposed pad is absent-this variant uses standard SC70, not µDFN.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | Normally closed analog terminal - conducts to COM when IN = LOW |
| 2 | IN | Digital control input - HIGH disables conduction (opens switch) |
| 3 | GND | Reference ground for logic and analog domains - must be low-impedance |
| 4 | COM | Common analog node - bidirectional I/O shared with NC/NO paths |
| 5 | V+ | Positive supply - powers internal logic and switch transistors; must be stable |
Key Features
| Feature | Design Value |
|---|---|
| NC default state | Ensures fail-safe signal continuity during power-up or logic fault conditions |
| SC70-5 ultra-small footprint | Enables high-density routing in space-constrained mobile PCBs (1.3mm × 0.8mm) |
| Rail-to-rail analog operation | Supports full GND-to-V+ signal swing without clipping or distortion |
| TTL/CMOS logic compatibility | Direct interface with 3.3V/5V microcontrollers and FPGAs without level shifters |
| Bidirectional signal flow | Eliminates need to define input/output direction - simplifies schematic and layout |
Applications
| Cellular Phone Audio Routing | DSL Modem Line Interface |
|---|---|
|
Use Scenario: Switching microphone and earpiece signals between baseband processor and codec in dual-mode GSM/WCDMA handsets. IC Role / Device Role / Timing Role: NC SPST analog switch providing default-connected audio path that opens only during mute or mode change. Use Value: Prevents pop/click artifacts during power-on and eliminates need for external pull-up/pull-down resistors due to inherent NC behavior. |

|
Use Scenario: Sharing a single ADC input among multiple sensor channels on legacy PCMCIA-based data acquisition cards. IC Role / Device Role / Timing Role: Low-RON, low-charge-injection SPST switch ensuring accurate sampling with minimal settling error. Use Value: 5pC max charge injection prevents baseline shift in high-impedance sensor measurements; 10Ω RON minimizes gain error. |
Use Scenario: Enabling/disabling ECG electrode inputs in portable patient monitors powered by single-cell Li-ion batteries. IC Role / Device Role / Timing Role: Ultra-low-leakage (≤0.5nA) NC switch maintaining patient safety and signal integrity during standby. Use Value: Sub-nA off-leakage avoids DC offset errors in biopotential amplifiers; +2.0V minimum supply supports direct connection to 2.4V–3.6V battery rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4595EXK+T | Same NC function, identical SC70-5 package and pinout, but different top-mark (AAI vs AAK) | No functional difference - same electrical specs and thermal performance | Select MAX4595EXK+T only if AAI-marked units are preferred for traceability or legacy BOM alignment |
| ADG801BRJZ-REEL7 | NC SPST, 0.3Ω typical RON, but higher 10nA max off-leakage and +1.8V to +5.5V supply range | Better RON for precision instrumentation; less suitable for ultra-low-leakage medical sensing | Choose ADG801BRJZ-REEL7 where lower on-resistance outweighs leakage sensitivity - e.g., industrial DAC output switching |
Compared with MAX4595EXK+T, the MAX4597EXK+T offers identical functionality and packaging but distinct traceability marking; versus ADG801BRJZ-REEL7, MAX4597EXK+T provides superior leakage performance and tighter charge injection control at the expense of slightly higher RON, making it preferable for battery-powered, low-noise signal routing.

FAQ
What is the default switch state of the MAX4597EXK+T?
The MAX4597EXK+T is a normally closed (NC) analog switch: it conducts between the NC and COM pins when the IN pin is logic LOW (≤0.8V), and opens (high impedance) when IN is driven HIGH (≥2.4V at +5V supply). This fail-safe behavior ensures signal continuity during power-up or controller reset, and is confirmed in the truth table and pin configuration diagrams of the MAX4594–MAX4597 datasheet.
Does the MAX4597EXK+T support rail-to-rail analog signals?
Yes, the MAX4597EXK+T supports analog signals from GND to V+ across its NC, COM, and NO pins. Its complementary MOSFET structure maintains low and flat on-resistance over the full supply range, verified in the "On-Resistance vs. COM Voltage" plots (Figures 1–3) and specified in the Electrical Characteristics table for analog signal range = 0V to V+.
What is the maximum allowable supply voltage for the MAX4597EXK+T?
The absolute maximum rating for V+ is +6V, but the recommended operating range is +2.0V to +5.5V. Operation above +5.5V risks permanent damage, as stated in the Absolute Maximum Ratings table. At +5.5V, parameters such as RON, leakage, and switching time remain within specification limits per the Electrical Characteristics tables.
Can the MAX4597EXK+T be used in bidirectional signal paths?
Yes, the MAX4597EXK+T is fully bidirectional: signals pass equally well from NC to COM or COM to NC, with identical RON, leakage, and bandwidth in both directions. This is explicitly stated in the Pin Description section ("NO, NC, and COM pins are identical and interchangeable") and validated by symmetric test configurations in Figures 2–5 of the datasheet.
Is the SC70-5 package of the MAX4597EXK+T lead-free and RoHS-compliant?
Yes, the MAX4597EXK+T is manufactured in a lead-free, RoHS-compliant SC70-5 package. This is confirmed by Maxim's packaging documentation and material declarations, and the "+T" suffix in the part number denotes tape-and-reel packaging compatible with standard SMT assembly processes.
