Product details
Overview
MAX4658ESA+T 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, 150mA continuous current handling, and rail-to-rail signal switching - used in audio routing, xDSL modems, and redundant backup systems.
For engineers reviewing the MAX4658ESA+T datasheet, MAX4658ESA+T pinout, MAX4658ESA+T application, or MAX4658ESA+T equivalent, this page delivers verified electrical specs, SO-8 package layout, real-world use cases, and two validated alternative parts for relay-replacement and high-voltage analog switching designs.
Technical Context
The MAX4658ESA+T implements a parallel N-channel/P-channel MOSFET switch architecture with proprietary body-drive sensing to eliminate voltage-drop limitations across the channel, enabling stable 150mA continuous conduction without parasitic diode turn-on. Its TTL/CMOS-compatible digital input controls bidirectional analog signal flow between COM and NO terminals.
It supports asymmetrical dual-supply operation (e.g., V+ = +12V, V− = −5V) within a 40V total V+–V− range, maintains ≤1nA off-leakage at +25°C, and delivers 210MHz −3dB bandwidth with <23pC charge injection - critical for low-distortion audio and high-fidelity test equipment signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at ±15V supplies - ensures minimal voltage drop and power loss when switching 150mA loads. |
| Continuous Current | ±150mA - enables direct replacement of electromechanical relays in medium-power analog paths. |
| Analog Signal Range | Rail-to-rail (V− to V+) - supports full-swing signals without clipping in ±15V or +12V systems. |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves signal integrity in high-impedance sensor or precision audio circuits. |
| Turn-On/Off Time | 140ns/65ns typical (RL = 100Ω, CL = 35pF) - suitable for fast-switching applications like multiplexed test fixtures. |
| Charge Injection | 23pC typical - limits voltage glitch on sampled nodes in data acquisition front-ends. |
| Supply Range | +9V to +40V (single) or ±4.5V to ±20V (dual) - accommodates industrial, telecom, and legacy analog system rails. |
Pinout & Package
MAX4658ESA+T is housed in an 8-pin SO (Small Outline) package per JEDEC MS-012, with exposed paddle not present (non-EP variant). Pin 1 is COM (analog common), Pin 4 is V+, Pin 6 is IN (digital control), Pin 7 is V−, Pin 8 is NO (normally open), and Pins 2/5 are no-connect. GND is on Pin 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM | Analog common terminal - connects to load or signal source; bidirectional current path. |
| 2, 5 | N.C. | No internal connection - must be left unconnected; no routing or grounding required. |
| 3 | GND | Ground reference - provides return path for digital logic and supply decoupling. |
| 4 | V+ | Positive supply input - accepts +9V to +40V (single) or up to +20V (dual). |
| 6 | IN | Digital control input - TTL/CMOS compatible; logic high turns switch ON (connects COM–NO). |
| 7 | V− | Negative supply input - accepts −4.5V to −20V (dual) or 0V (single-supply mode). |
| 8 | NO | Normally open analog terminal - forms closed path with COM only when IN = high. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs spanning full V− to V+ range - eliminates level-shifting in ±15V op-amp or DAC interfaces. |
| 1Ω max RON flatness | Ensures consistent gain and linearity across signal swing - critical for audio and instrumentation accuracy. |
| No VL supply required | Eliminates need for separate logic-level supply - simplifies PCB design and reduces BOM count. |
| 210MHz −3dB bandwidth | Preserves signal fidelity up to video and broadband communication frequencies. |
| Pin compatibility with DG418 | Enables drop-in upgrade from legacy analog switches without layout changes. |

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, identical pinout, but rated for 300mA continuous current (vs. 150mA); higher power dissipation. | Preferred where higher load current is required; unsuitable if thermal budget or layout is constrained for MAX4658ESA+T's lower power profile. | Select MAX4656ESA+ only if ≥300mA continuous conduction is needed and thermal margin allows. |
| ADG1419BRMZ | 10Ω RON, ±15V supply, but 200mA continuous rating and 125ns tON; uses different logic polarity (active-low enable). | Requires inverted control signal and has higher supply current (250µA vs. 130µA); better for low-THD (<0.003%) audio but less suited for high-reliability relay replacement. | Choose ADG1419BRMZ for ultra-low distortion audio paths; avoid if logic inversion or higher quiescent current conflicts with system design. |
Compared with MAX4658ESA+T, MAX4656ESA+ offers higher current capacity at the cost of increased thermal load, while ADG1419BRMZ trades control simplicity and leakage performance for superior THD - making MAX4658ESA+T optimal for cost-sensitive, thermally constrained relay-replacement in telecom and industrial backup systems.

FAQ
What is the maximum continuous current rating for MAX4658ESA+T?
The MAX4658ESA+T is rated for ±150mA continuous current through the COM and NO terminals under specified thermal conditions. This value is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics section for MAX4657/MAX4658 variants. Exceeding this limit risks thermal shutdown or permanent damage, especially in non-heat-sinked SO-8 layouts.
Does MAX4658ESA+T require a separate logic-level supply (VL)?
No, MAX4658ESA+T does not require a VL supply. Its digital input (Pin 6) is fully TTL/CMOS compatible across its entire operating temperature range (−40°C to +85°C), accepting VIH ≥ 2.4V and VIL ≤ 0.8V directly from standard 3.3V or 5V logic without level translation - a key simplification over older analog switch families.
Is MAX4658ESA+T pin-compatible with industry-standard alternatives?
Yes, MAX4658ESA+T is pin-compatible with the DG418 analog switch in the same SO-8 package. Pin mapping (COM, NO, IN, V+, V−, GND) matches exactly, enabling direct replacement without PCB modification - provided supply voltages and signal ranges fall within MAX4658ESA+T's ±4.5V to ±20V dual-supply or +9V to +40V single-supply limits.
What is the typical on-resistance flatness of MAX4658ESA+T over its signal range?
The MAX4658ESA+T exhibits ≤1Ω maximum on-resistance flatness (RFLAT(ON)) over its full analog signal range when tested at ±15V supplies and +25°C. This tight flatness ensures minimal gain variation and harmonic distortion across rail-to-rail input swings - a critical parameter verified in the Electrical Characteristics table under "On-Resistance Flatness".
Can MAX4658ESA+T operate from asymmetric dual supplies?
Yes, MAX4658ESA+T supports asymmetric dual-supply operation - for example, V+ = +12V and V− = −5V - as long as the total V+–V− differential remains ≤40V and each supply stays within its absolute maximum ratings (V+ to GND ≤ +44V, V− to GND ≥ −44V). This flexibility is explicitly stated in the General Description and enables tailored biasing in mixed-signal systems.
