Product details
Overview
MAX4657ESA from Maxim Integrated is a normally closed (NC), 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 max on-resistance at ±15V supplies, supports ±150mA continuous current and ±300mA peak 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 MAX4657ESA datasheet, MAX4657ESA pinout, MAX4657ESA application, or MAX4657ESA equivalent, this device is selected for high-fidelity audio routing, redundant power-path switching, and test equipment signal conditioning where low RON flatness (1Ω max), <1nA off-leakage at +25°C, and 210MHz bandwidth are critical design requirements.
Technical Context
The MAX4657ESA 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. This enables stable conduction across the full ±20V dual-supply or +40V single-supply range without parasitic diode turn-on.
Its TTL/CMOS-compatible digital control input (VIH = 2.4V, VIL = 0.8V) directly drives the switch with no VL bias required, and its rail-to-rail analog path handles signals from V− to V+ with 1Ω max RON flatness over −5V to +5V, ensuring minimal THD (0.007% at 20Hz–20kHz) in audio applications.
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 continuous loads. |
| Continuous Current Rating | ±150mA - supports high-current analog paths such as audio amplifiers or backup power rails without derating. |
| RON Flatness | 1Ω max over −5V to +5V signal range - preserves signal integrity and linearity in precision AC-coupled circuits. |
| Off-Leakage Current | 1nA max at TA = +25°C - prevents DC error accumulation in high-impedance sensor or measurement front-ends. |
| Bandwidth | 210MHz - enables clean switching of fast video, RF sampling, or high-speed data signals without attenuation. |
| Supply Range | +9V to +40V (single) or ±4.5V to ±20V (dual) - accommodates wide-voltage industrial and telecom power domains. |
| Charge Injection | 23pC - limits transient glitches during switching in sample-and-hold or multiplexer applications. |
Pinout & Package
MAX4657ESA is housed in an 8-pin SOIC (SO) package with standard .150" width, JEDEC MS012 outline, and RoHS-compliant lead finish. The exposed paddle variant is not used in this SO version.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM | Analog common terminal - connects to load or signal source; bidirectional conduction path. |
| 2, 5 | N.C. | No internal connection - must be left unconnected; no PCB trace or thermal pad required. |
| 3 | GND | Digital ground reference - ties logic interface and substrate to system ground plane. |
| 4 | V+ | Positive supply input - sets upper rail for dual-supply operation or sole supply for single-supply mode. |
| 6 | IN | Digital control input - active-low logic disables NC path (open circuit); TTL/CMOS compatible. |
| 7 | V− | Negative supply input - defines lower rail in dual-supply configuration; tied to GND for single-supply use. |
| 8 | NC | Normally closed analog terminal - conducts to COM when IN = logic low; open when IN = logic high. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals spanning V− to V+ - eliminates level-shifting in mixed-supply systems like PBX line cards. |
| No VL bias required | Eliminates need for auxiliary logic supply - simplifies BOM and layout in space-constrained test equipment. |
| 10Ω max on-resistance | Minimizes insertion loss and self-heating in 25Ω–100Ω impedance-matched audio and comms paths. |
| 210MHz bandwidth | Preserves edge integrity for video sync pulses and broadband instrumentation signals up to 100MHz. |
| 1nA max off-leakage | Prevents drift in high-Z medical sensor interfaces or precision thermocouple amplifiers over temperature. |
Applications
| Relay Replacement | Audio Signal Routing |
|---|---|
Use Scenario: Replacing electromechanical relays in DSLAM line-card protection circuits requiring >1M cycle life and sub-µs switching. IC Role / Device Role / Timing Role: Normally closed (NC) analog switch providing fail-safe continuity until fault detection triggers IN high. Use Value: Eliminates mechanical wear, bounce, and coil drive circuitry while maintaining <10Ω path resistance under 150mA load. |
Use Scenario: Multiplexing stereo analog outputs between main amplifier and headphone jack in PC multimedia boards. IC Role / Device Role / Timing Role: Low-THD SPST switch routing line-level audio (±2V) with minimal crosstalk and pop/click suppression. Use Value: 0.007% THD and 25pF off-capacitance prevent audible distortion and preserve frequency response to 20kHz. |
| Test Equipment Signal Path | Redundant Power Backup |

Use Scenario: Providing seamless switchover between primary and backup 12V power rails in telecom shelf controllers. IC Role / Device Role / Timing Role: NC switch maintaining default power path; fast turn-off (<150ns) isolates failed rail upon controller command. Use Value: ±150mA continuous rating and 10Ω RON ensure <1.5V drop at full load, preserving downstream voltage margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4655ESA | Same SO-8 package and pinout, but rated for ±300mA continuous current and higher power dissipation (471mW vs. 471mW at +70°C). | Preferred where higher load current (e.g., 200mA audio drivers) demands lower RON drift and thermal margin. | Select MAX4655ESA only if continuous current exceeds 150mA; otherwise MAX4657ESA offers better cost/performance balance. |
| ADG1419BRMZ | 12Ω max RON, ±200mA continuous, LFCSP-10 package - not pin-compatible; requires PCB redesign. | Better THD (0.003%) and lower charge injection (12pC), suited for high-precision instrumentation over telecom. | Choose ADG1419BRMZ when THD and charge injection dominate over footprint and pin compatibility. |
Compared with MAX4655ESA, MAX4657ESA trades 150mA continuous current for tighter thermal envelope in SO-8; versus ADG1419BRMZ, it offers direct SO-8 drop-in capability and superior off-isolation (−77dB) at 1MHz, making it optimal for cost-sensitive telecom switching.

FAQ
What is the maximum continuous current rating for MAX4657ESA?
The MAX4657ESA supports ±150mA continuous current through its COM and NC 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 current may cause thermal shutdown or permanent damage.
Is MAX4657ESA pin-compatible with DG417 or DG418?
Yes, MAX4657ESA is pin-compatible with DG417 and DG418 in the 8-pin SOIC package, sharing identical pin assignments for COM, NC/NO, IN, V+, V−, and GND. However, MAX4657ESA provides significantly lower on-resistance (10Ω vs. ~35Ω), higher current capability (±150mA vs. ±20mA), and wider supply range (±20V vs. ±15V), making it a performance upgrade without layout changes.
Does MAX4657ESA require a separate logic supply (VL)?
No, MAX4657ESA does not require a VL pin or auxiliary logic supply. Its digital control input (IN) is fully TTL/CMOS compatible with VIH = 2.4V and VIL = 0.8V referenced to GND, operating directly from the same V+ and V− supplies used for the analog path. This eliminates external level shifters and reduces system complexity in single-supply or asymmetric dual-supply configurations.
What is the off-isolation performance of MAX4657ESA at 1MHz?
At 1MHz, the MAX4657ESA delivers −77dB off-isolation (VISO) into a 50Ω load, as measured per Figure 5 in the datasheet. This value reflects strong signal rejection between NC and COM terminals when the switch is open, critical for preventing crosstalk in dense multiplexer or test matrix designs. Off-isolation degrades with frequency but remains >−40dB up to 100MHz.
Can MAX4657ESA operate from a single +12V supply?
Yes, MAX4657ESA supports single-supply operation from +9V to +40V. With V+ = +12V and V− tied to GND, it maintains rail-to-rail analog signal handling (0V to +12V), 10Ω max RON, and ±150mA continuous current capability. Input logic thresholds remain valid (VIH = 2.4V, VIL = 0.8V), and all dynamic specs - including 210MHz bandwidth and 150ns turn-off time - are preserved per Electrical Characteristics tables.
