Product details
Overview
MAX4658EUA+ from Maxim Integrated is a normally open (NO), single-pole/single-throw (SPST), high-current CMOS analog switch rated for ±4.5V to ±20V dual-supply or +9V to +40V single-supply operation, with 10Ω max on-resistance at ±15V, 150mA continuous current handling, and rail-to-rail signal capability-used in audio routing, xDSL modems, and relay-replacement circuits where low leakage and fast switching are critical.
For engineers reviewing the MAX4658EUA+ datasheet, MAX4658EUA+ pinout, MAX4658EUA+ application, or MAX4658EUA+ equivalent, this page delivers verified electrical parameters, package-specific pin mapping, real-world use scenarios, and validated alternative parts for industrial signal-switching designs requiring robust current-handling and sub-1nA off-leakage at +25°C.
Technical Context
The MAX4658EUA+ implements a parallel N-channel/P-channel MOSFET switch architecture with proprietary body-drive sensing to eliminate voltage-drop limitations typical of standard CMOS switches-enabling full rail-to-rail conduction without parasitic diode turn-on. It operates across asymmetric supply configurations (e.g., V+ = +24V, V− = −5V) within a 40V total range.
Its digital control interface accepts TTL/CMOS logic levels (VIH = 2.4V min, VIL = 0.8V max) independent of supply rails, and features no VL pin requirement. Signal integrity is maintained via 1Ω max RON flatness over ±10V input range and 210MHz −3dB bandwidth under ±15V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at ±15V supplies - ensures minimal voltage drop (<1.5V at 150mA) and power loss in high-current analog paths. |
| Continuous Current Rating | ±150mA - supports sustained load switching in audio amplifiers, backup systems, and telecom line interfaces. |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves signal fidelity in precision sensor multiplexing and high-impedance measurement circuits. |
| Supply Range | ±4.5V to ±20V dual or +9V to +40V single - enables direct integration into industrial ±15V, automotive 24V, and telecom 36V systems. |
| Turn-On/Turn-Off Time | 140ns / 65ns typ at +25°C - meets timing requirements for fast data acquisition and TDM channel switching. |
| Bandwidth | 210MHz −3dB - supports clean transmission of audio, video, and broadband communication signals up to 100MHz. |
| RON Flatness | 1Ω max over ±10V signal range - maintains consistent gain and linearity in variable-gain amplifier and filter-switching applications. |
Pinout & Package
MAX4658EUA+ is housed in an 8-pin µMAX package (3.0mm × 3.0mm, 0.8mm height) with exposed paddle (EP) for thermal enhancement. The package is RoHS-compliant and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM | Analog common terminal - connects to load or signal path; bidirectional conduction when switch is ON. |
| 2, 5 | N.C. | No internal connection - must be left unconnected; not tied to ground or supply. |
| 3 | GND | Digital ground reference - provides return path for control logic and stabilizes internal bias networks. |
| 4 | V+ | Positive supply input - powers P-channel device and level-shifting circuitry; EP must be connected to V+ for thermal performance. |
| 6 | IN | Digital control input - active-high logic; drives switch ON (closed) when IN = high (≥2.4V). |
| 7 | V− | Negative supply input - powers N-channel device; required for dual-supply operation and rail-to-rail analog swing. |
| 8 | NO | Normally open analog terminal - connects to COM only when IN is high; isolated from COM when IN is low. |
Key Features
| Feature | Design Value |
|---|---|
| No VL pin required | Eliminates need for separate logic-level supply-simplifies PCB layout and reduces BOM count in mixed-voltage systems. |
| Rail-to-rail signal handling | Supports analog inputs from V− to V+, enabling full dynamic range utilization in ±15V op-amp circuits and DAC output switching. |
| 1Ω max RON flatness | Ensures <0.1% gain error across ±10V signal range-critical for precision instrumentation and calibrated test equipment. |
| 210MHz bandwidth | Preserves signal integrity for composite video, USB 1.1, and ISDN baseband signals without external equalization. |
| Pin compatibility with DG418 | Enables drop-in replacement in legacy designs using DG418-based routing, reducing redesign effort and qualification time. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4656EUA+ | Same package and pinout; higher 300mA continuous current rating but identical 10Ω RON and leakage specs. | Preferred where load current exceeds 150mA (e.g., driving 50Ω video lines or high-side LED arrays). | Select MAX4656EUA+ only if design requires >150mA continuous conduction; otherwise MAX4658EUA+ offers better thermal margin at lower current. |
| ADG1419BRMZ-REEL7 | 1.8Ω RON max at ±15V, 200mA continuous, but limited to ±20V max supply and no exposed paddle. | Better for ultra-low-distortion audio or precision data acquisition where RON flatness <0.5Ω is mandatory. | Choose ADG1419BRMZ-REEL7 when sub-2Ω RON and <0.001% THD outweigh need for 40V single-supply operation or thermal robustness. |
Compared with MAX4656EUA+, MAX4658EUA+ trades 150mA current capacity for improved thermal efficiency in µMAX-EP packaging; versus ADG1419BRMZ-REEL7, it offers wider supply range (+9V to +40V) and integrated exposed paddle cooling-making it optimal for high-voltage industrial switching where moderate RON is acceptable.

FAQ
What is the maximum continuous current rating for MAX4658EUA+?
The MAX4658EUA+ supports ±150mA continuous current through its COM and NO terminals under specified thermal conditions. This rating applies across the full operating temperature range (−40°C to +85°C) and is validated per the Absolute Maximum Ratings table in the official datasheet. Exceeding this value risks thermal shutdown or permanent damage, especially in the 8-pin µMAX package without exposed paddle thermal connection.
Does MAX4658EUA+ require a separate logic-level supply (VL pin)?
No, MAX4658EUA+ does not require a VL pin. Its digital control input (IN) is TTL/CMOS compatible and operates directly from the same V+ and V− supplies used for analog switching-eliminating the need for auxiliary voltage rails. This simplifies system design in mixed-supply environments and reduces component count compared to older analog switches requiring dedicated logic supplies.
Can MAX4658EUA+ operate from a single +24V supply?
Yes, MAX4658EUA+ supports single-supply operation from +9V to +40V. With V+ = +24V and V− tied to GND, it delivers rail-to-rail analog switching from 0V to +24V. The on-resistance remains ≤33Ω (typical) under these conditions, and all timing, leakage, and bandwidth specifications remain valid per the Single-Supply Electrical Characteristics table in the datasheet.
What is the exposed paddle (EP) connection requirement for MAX4658EUA+?
The exposed paddle (EP) on the MAX4658EUA+ µMAX package must be soldered to V+ for optimal thermal performance and reliability. This connection lowers junction-to-board thermal resistance, enabling the device to sustain its 150mA continuous current rating at elevated ambient temperatures. Leaving EP floating or connecting it to GND violates the Absolute Maximum Ratings and may cause premature thermal failure.
Is MAX4658EUA+ pin-compatible with industry-standard alternatives?
Yes, MAX4658EUA+ is pin-compatible with the DG418 analog switch, sharing identical 8-pin µMAX pinout and logic polarity. This allows direct replacement in existing DG418-based designs without PCB modification. However, MAX4658EUA+ offers superior specifications-including 10Ω vs. 45Ω on-resistance, 210MHz vs. 100MHz bandwidth, and ±150mA vs. ±30mA current rating-delivering measurable performance gains in signal integrity and power handling.
