Product details
Overview
MAX4597EXK-T from Maxim Integrated is a normally closed (NC) single-pole/single-throw (SPST) CMOS analog switch optimized for low-voltage, single-supply operation from +2.0V to +5.5V. It delivers 10Ω max on-resistance, 1.5Ω max on-resistance flatness over the full analog signal range, and <40ns switching times, enabling precision audio/video routing in battery-powered handheld devices.
For engineers reviewing the MAX4597EXK-T datasheet, MAX4597EXK-T pinout, MAX4597EXK-T application, or MAX4597EXK-T equivalent, key selection criteria include guaranteed 5pC max charge injection, -80dB off-isolation at 1MHz, 300MHz -3dB bandwidth, TTL/CMOS logic compatibility, and SC70-5 package suitability for space-constrained PCB layouts.
Technical Context
The MAX4597EXK-T implements a bidirectional SPST analog switch with NC default state, where COM connects to NC when IN = LOW and disconnects when IN = HIGH. Its CMOS architecture ensures symmetrical conduction in both directions and minimal signal distortion across the full 0V to V+ analog range.
It operates without external biasing, supports rail-to-rail analog signals, and maintains stable RON flatness (<1.5Ω) and low leakage (<0.5nA off-state) across -40°C to +85°C. Charge injection is tightly controlled at ≤5pC, critical for sample-and-hold and multiplexer applications requiring low glitch energy.
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 paths up to 10mA. |
| RON Flatness | 1.5Ω max over full analog range - preserves signal linearity and gain accuracy in precision instrumentation. |
| Switching Time (tON/tOFF) | 35ns/40ns max - enables high-speed channel selection in multi-source audio/video systems. |
| Off-Isolation | -80dB at 1MHz - suppresses crosstalk between inactive channels in dense routing architectures. |
| Charge Injection | 5pC max - limits voltage glitch on sampled nodes, supporting accurate ADC front-end switching. |
| Bandwidth (-3dB) | 300MHz at +25°C - supports wideband video (e.g., VGA, SDI) and RF-adjacent baseband signals. |
| Supply Range | +2.0V to +5.5V single supply - eliminates need for dual rails in portable designs powered by Li-ion or 3.3V systems. |
Pinout & Package
MAX4597EXK-T is packaged in a 5-pin SC70-5 (1.6mm × 1.6mm × 0.9mm), optimized for high off-isolation and minimal board footprint. The exposed pad is absent-this variant uses standard SC70, not µDFN.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | Normally closed analog terminal - connects to COM when control input is LOW; bidirectional signal path. |
| 2 | IN | Digital control input - TTL/CMOS-compatible; LOW enables NC-COM connection, HIGH opens the switch. |
| 3 | GND | Analog and digital ground reference - must be low-impedance; shared return for all signal and supply paths. |
| 4 | COM | Common analog terminal - connects to NC (pin 1) when IN = LOW; serves as bidirectional I/O node. |
| 5 | V+ | Positive supply rail - powers internal CMOS switch core; must be decoupled locally with 0.1µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Normally Closed (NC) Default | Ensures fail-safe signal continuity during power-up or control loss - critical for safety-critical audio mute or sensor monitoring paths. |
| Ultra-Low Charge Injection (≤5pC) | Minimizes transient voltage spikes on high-impedance nodes, enabling reliable use in sample-and-hold and multiplexed ADC inputs. |
| 300MHz Bandwidth | Supports composite video, RGB, and broadband analog signals without attenuation or phase distortion in consumer and telecom equipment. |
| SC70-5 Package | Reduces PCB area by >50% vs. SOIC-8 - ideal for smartphones, wearables, and compact IoT edge nodes with strict size constraints. |
| Rail-to-Rail Analog Operation | Accepts input signals from GND to V+, eliminating level-shifting circuitry and simplifying system-level signal chain design. |

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 | Identical SC70-5 package, NC function, and electrical specs - differs only in top-mark (AAI vs AAK); pinout and performance fully matched. | No functional difference - used interchangeably in same designs; AAK marking confirms MAX4597 revision per Maxim's ordering matrix. | Select MAX4597EXK-T when traceability to latest production revision or specific top-mark compliance is required. |
| TMUX1574DSGR | 4-channel SPDT, 5.5Ω RON, but requires dual supply (±2.5V) or level-shifted control; no NC default state. | Not suitable for fail-safe NC operation; better for multi-channel routing where density outweighs default-state requirement. | Choose TMUX1574DSGR only if multi-channel integration and lower RON justify redesigning control logic and supply architecture. |
Compared with MAX4595EXK-T, MAX4597EXK-T offers identical functionality and pinout with verified AAK top-mark alignment to Maxim's latest wafer lot; versus TMUX1574DSGR, MAX4597EXK-T provides true NC fail-safe behavior, single-supply simplicity, and proven 300MHz bandwidth in ultra-small SC70-5 - making it optimal for space- and reliability-constrained portable analog routing.

FAQ
What is the default switch state of the MAX4597EXK-T?
The MAX4597EXK-T is a normally closed (NC) analog switch: when the IN pin is logic LOW, the NC pin connects to the COM pin; when IN is HIGH, the switch opens. This fail-safe behavior ensures signal continuity during power-up or control signal loss, making MAX4597EXK-T ideal for audio mute paths or sensor monitoring where uninterrupted connection is critical.
Does the MAX4597EXK-T support rail-to-rail analog signals?
Yes, the MAX4597EXK-T supports analog signals from GND to V+ across its entire operating supply range (+2.0V to +5.5V). Its CMOS architecture enables bidirectional conduction with minimal RON variation - confirmed by ≤1.5Ω flatness over the full 0V to V+ range at +5V supply - allowing direct interfacing with op-amps, ADCs, and DACs without level-shifting circuitry.
What is the maximum allowable supply voltage for the MAX4597EXK-T?
The absolute maximum supply voltage for MAX4597EXK-T is +6V, but the recommended operating range is +2.0V to +5.5V. Exceeding +5.5V risks violating the device's absolute maximum ratings and may degrade RON, leakage, or reliability. For robust operation in battery-powered systems, design margins should keep V+ ≤5.5V, especially under load or temperature extremes.
Can the MAX4597EXK-T be used in audio applications requiring low distortion?
Yes, the MAX4597EXK-T delivers 0.05% THD at 5Vp-p, 20Hz–20kHz into 600Ω - meeting requirements for high-fidelity headphone output switching and microphone path routing. Combined with 300MHz bandwidth and 5pC max charge injection, MAX4597EXK-T minimizes audible artifacts like pop/click and harmonic distortion in portable audio subsystems.
Is the SC70-5 package of the MAX4597EXK-T lead-free and RoHS-compliant?
Yes, the MAX4597EXK-T in SC70-5 package is manufactured to RoHS Directive 2011/65/EU standards and uses lead-free terminations. Per Maxim's packaging documentation, the SC70-5 variant (order code EXK-T) conforms to JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), and the top mark "AAK" identifies the RoHS-compliant, halogen-free version qualified for industrial temperature range (-40°C to +85°C).
