Product details
Overview
MAX4658ESA+ from Maxim Integrated is a normally open (NO), single-pole/single-throw (SPST), high-current CMOS analog switch optimized for rail-to-rail signal routing in industrial and telecom systems. It delivers ≤10Ω on-resistance at ±15V supplies, supports ±150mA continuous/±300mA peak switching current, and operates from +9V to +40V single supply or ±4.5V to ±20V dual supply - enabling robust relay replacement in xDSL modems and PBX backup paths.
For engineers reviewing the MAX4658ESA+ datasheet, MAX4658ESA+ pinout, MAX4658ESA+ application, or MAX4658ESA+ equivalent, this page provides verified specifications, SO-8 package terminal mapping, real-world audio and communication system use cases, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The MAX4658ESA+ implements a parallel N-channel/P-channel MOSFET switch architecture with proprietary body-drive sensing to eliminate voltage-drop limitations inherent in standard CMOS switches. This enables stable on-resistance across full rail-to-rail analog signal ranges (VCOM = V− to V+) without parasitic diode conduction.
Its TTL/CMOS-compatible digital control input (IN) directly drives the switch with no VL bias required, while internal protection diodes clamp signals exceeding V+ or V− - limiting forward current per Absolute Maximum Ratings. Off-isolation reaches −77dB at 1MHz, and charge injection is only 1pC (typ) under single-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPST, Normally Open (NO) - conducts only when IN = logic high; open-circuit state by default for fail-safe signal isolation. |
| On-Resistance (RON) | ≤10Ω max at ±15V dual supply - ensures minimal voltage drop (<1.5V at 150mA) and low power loss in high-current analog paths. |
| Continuous Switch Current | ±150mA - supports sustained load switching in audio routing and redundant telecom signal paths without thermal derating. |
| Peak Switch Current | ±300mA (1ms, 10% duty cycle) - handles transient surges in test equipment and modem line drivers. |
| Off-Leakage Current | ≤10nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and precision audio circuits. |
| Supply Range | +9V to +40V (single) or ±4.5V to ±20V (dual) - accommodates wide dynamic range in industrial power rails and legacy telecom voltages. |
| Bandwidth | 210MHz - maintains fidelity for broadband signals up to video frequencies in PC multimedia boards. |
Pinout & Package
MAX4658ESA+ uses an 8-pin SO (Small Outline) package (SOIC-N, 150-mil width), with exposed paddle not present in this variant (per ordering table: MAX4658ESA has no EP suffix). Pin 1 is COM (common terminal); Pin 8 is NO (normally open analog terminal); Pin 6 is IN (TTL/CMOS-compatible digital control input).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COM) | Analog Switch Common | Shared connection point for bidirectional analog signal path; must be routed with controlled impedance in RF-sensitive applications. |
| 2, 5 (N.C.) | No Internal Connection | Unbonded pins - electrically isolated; may be left floating or tied to ground for mechanical stability (no electrical function). |
| 3 (GND) | Ground Reference | Return path for digital control logic and internal biasing; requires low-inductance connection to minimize switching noise coupling. |
| 4 (V+) | Positive Supply Input | Accepts +9V to +40V (single) or up to +20V (dual); decoupling capacitor (≥0.1µF) mandatory within 5mm of pin. |
| 6 (IN) | Digital Control Input | TTL/CMOS-compatible (VIL ≤ 0.8V, VIH ≥ 2.4V); no pull-up/down required; logic high enables NO-to-COM conduction. |
| 7 (V−) | Negative Supply Input | Accepts −4.5V to −20V (dual supply only); must be connected even in single-supply mode where V− = GND (0V). |
| 8 (NO) | Analog Switch Normally Open | Open-circuit terminal by default; connects to COM only when IN = high; rated for ±150mA continuous current. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from V− to V+ without clipping - essential for ±12V audio and +24V industrial sensor interfaces. |
| 1Ω max RON flatness | Ensures consistent gain and minimal THD (<0.007%) across full signal swing - critical for high-fidelity audio routing. |
| No VL bias required | Eliminates need for auxiliary logic supply - simplifies PCB layout and reduces BOM count in space-constrained designs. |
| −77dB off-isolation at 1MHz | Prevents crosstalk between active and inactive channels in multi-path communication systems like PBX and xDSL. |
| 1pC typical charge injection | Minimizes voltage glitches during switching - avoids audible pops in audio systems and data errors in sampled analog front-ends. |
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 |
|---|---|---|---|
| MAX4656ESA+ | Same SO-8 package and pinout, but rated for ±300mA continuous current (vs. ±150mA for MAX4658ESA+); higher power dissipation (471mW vs. 471mW at +70°C, but higher thermal resistance). | Preferred in high-current relay-replacement roles (e.g., motor control feedback paths) where >150mA continuous load is required. | Select MAX4656ESA+ only if design demands >150mA continuous current; otherwise MAX4658ESA+ offers better thermal margin at lower cost. |
| ADG1419BRMZ | Single-supply only (+5V to +36V), 0.7Ω typical RON, but lower peak current (±200mA) and no dual-supply capability; uses MSOP-10 package. | Suitable for single-rail industrial I/O modules, but cannot replace MAX4658ESA+ in ±15V audio or telecom systems requiring true bipolar operation. | Choose ADG1419BRMZ for compact single-supply designs where ultra-low RON outweighs dual-supply flexibility and higher peak current. |
Compared with MAX4656ESA+, MAX4658ESA+ trades 2× continuous current capacity for improved thermal efficiency in SO-8 packaging; versus ADG1419BRMZ, it retains full dual-supply operation and higher surge tolerance at the cost of slightly higher RON, making it uniquely suited for telecom and audio infrastructure.

FAQ
What is the maximum continuous current rating for MAX4658ESA+?
The MAX4658ESA+ supports ±150mA continuous current at the COM and NO terminals under specified thermal conditions (TA ≤ +70°C). This rating is validated per Absolute Maximum Ratings and Electrical Characteristics tables in the official datasheet, and applies across the full operating temperature range (−40°C to +85°C) with appropriate PCB copper area for heat dissipation. Exceeding this limit risks thermal shutdown or permanent damage.
Does MAX4658ESA+ require a separate logic supply (VL pin)?
No, MAX4658ESA+ does not have a VL pin and requires no auxiliary logic supply. Its digital input (IN) is fully TTL/CMOS compatible with VIL ≤ 0.8V and VIH ≥ 2.4V referenced to GND, operating directly from the same V+ and V− supplies used for analog switching. This eliminates external level-shifting circuitry and simplifies power domain management in mixed-voltage systems.
Can MAX4658ESA+ operate with only a single positive supply?
Yes, MAX4658ESA+ supports single-supply operation from +9V to +40V, with V− connected to GND (0V). The device maintains rail-to-rail analog signal handling (0V to V+) and all key specifications - including ≤10Ω RON, ±150mA continuous current, and −77dB off-isolation - are guaranteed under single-supply conditions per the Electrical Characteristics table.
What is the on-resistance flatness specification for MAX4658ESA+?
MAX4658ESA+ guarantees ≤1Ω maximum on-resistance flatness (RFLAT(ON)) over its specified analog signal range, measured as the difference between max and min RON while sweeping VCOM from V− to V+. This tight flatness ensures minimal THD (<0.007%) and consistent gain across full signal swings - a critical parameter for high-fidelity audio routing and precision instrumentation applications.
Is MAX4658ESA+ pin-compatible with industry-standard analog switches?
MAX4658ESA+ is pin-compatible with DG417 and DG418 devices in the same SO-8 package footprint, sharing identical COM, NO, IN, V+, V−, and GND pin assignments. However, note that DG417/DG418 are NC-type switches, whereas MAX4658ESA+ is NO-type - requiring inverted logic control in drop-in replacements. Always verify truth table alignment before substitution.
