Product details
Overview
MAX4657ESA+T from Maxim Integrated is a normally closed (NC), 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, relay replacement, and redundant backup systems.
For engineers reviewing the MAX4657ESA+T datasheet, MAX4657ESA+T pinout, MAX4657ESA+T application, or MAX4657ESA+T equivalent, key selection criteria include NC logic state, 150mA continuous current capability, SO-8 package thermal limits, and compatibility with ±15V/12V supply rails in high-reliability analog signal paths.
Technical Context
The MAX4657ESA+T implements an N-channel/P-channel MOSFET parallel switch architecture with proprietary body-drive sensing to eliminate voltage-drop limitations across the channel, enabling full rail-to-rail conduction without parasitic diode turn-on. It operates with TTL/CMOS-compatible digital control and requires no VL bias rail.
Its analog path supports bidirectional signal flow with 1nA max off-leakage at +25°C, 210MHz -3dB bandwidth, and 1Ω max RON flatness over ±10V signal range - critical for low-distortion audio and precision test equipment switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPST, Normally Closed (NC) - COM connects to NC when IN = logic low; breaks connection when IN = logic high. |
| On-Resistance (RON) | 10Ω max at ±15V supplies - ensures minimal insertion loss and voltage drop in high-current analog paths up to 150mA continuous. |
| Continuous Current Rating | ±150mA at COM/NC terminals - supports robust load switching in industrial I/O and telecom line cards without derating. |
| Supply Range | ±4.5V to ±20V dual or +9V to +40V single - enables wide dynamic range signal handling in mixed-voltage systems. |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves signal integrity in high-impedance sensor and measurement circuits. |
| Turn-On/Turn-Off Time | 140ns/65ns typical (RL = 200Ω, CL = 35pF) - supports fast multiplexing in automated test equipment and data acquisition. |
| Bandwidth | 210MHz -3dB - maintains fidelity for broadband signals including xDSL and audio up to 20kHz with 0.007% THD. |
Pinout & Package
MAX4657ESA+T is housed in an 8-pin SO (Small Outline) package per JEDEC MS-012, with exposed paddle not present (non-EP variant). Thermal resistance θJA = 170°C/W; recommended solder profile complies with IPC/JEDEC J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COM | Analog Switch Common | Main signal path terminal; connects bidirectionally to NC when switch is closed; must be routed with controlled impedance for 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, but no electrical function. |
| 3 - GND | Ground Reference | Primary return path for digital control and internal biasing; requires low-inductance connection to system ground plane. |
| 4 - V+ | Positive Supply Input | Accepts +9V to +40V (single) or up to +20V (dual); powers P-channel device and level-shifting circuitry. |
| 6 - IN | Digital Control Input | TTL/CMOS-compatible logic input; active-low control for NC function - drives internal gate drivers with <1µA leakage. |
| 7 - V- | Negative Supply Input | Accepts -4.5V to -20V (dual); powers N-channel device and sensing circuitry; must be decoupled near pin. |
| 8 - NC | Normally Closed Terminal | Analog input/output node that remains connected to COM when IN = low; rated for same current/voltage as COM. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ voltage swing without clipping or distortion - essential for ±15V op-amp interfaces and audio line-level routing. |
| No VL bias rail required | Eliminates need for auxiliary logic supply - simplifies PCB layout and reduces BOM count in space-constrained industrial modules. |
| 1Ω max RON flatness | Ensures consistent gain and phase response across entire signal range (±10V), critical for precision instrumentation and calibration systems. |
| 210MHz bandwidth with -2dB on-response | Enables clean switching of high-frequency signals including ADSL2+, VDSL, and video sync pulses without added filtering. |
| 150mA continuous current capability | Permits direct drive of solenoids, LEDs, and relay coils in programmable logic controllers without external buffers. |

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 NC logic, but rated for 300mA continuous current and higher power dissipation (471mW vs. 471mW at +70°C - identical SO rating). | Preferred where higher current loads (e.g., 25Ω speaker drivers) require lower RON temperature drift and enhanced thermal margin. | Select MAX4655ESA+ only if 300mA continuous rating is required; MAX4657ESA+T offers optimized cost/power trade-off for ≤150mA use cases. |
| ADG1419BRMZ | SPST NC switch in 10-lead MSOP; 8.5Ω RON, ±15V supply, but only 125mA continuous current and no exposed paddle option. | Suitable for space-constrained designs needing smaller footprint, but lacks SO-8 compatibility and thermal performance for sustained 150mA loads. | Choose ADG1419BRMZ for compact layouts with lower current demands; MAX4657ESA+T provides superior thermal reliability in SO-8 industrial formats. |
Compared with MAX4655ESA+, the MAX4657ESA+T trades 150mA continuous current for tighter thermal design in standard SO-8, while ADG1419BRMZ offers smaller size at the expense of current capacity and package compatibility - making MAX4657ESA+T optimal for cost-sensitive, thermally demanding NC switching in legacy SO footprints.

FAQ
What is the logic configuration of MAX4657ESA+T?
The MAX4657ESA+T is a normally closed (NC) SPST analog switch: when the IN pin is logic low (≤0.8V), COM is connected to NC; when IN is logic high (≥2.4V), the switch opens. This fail-safe behavior makes MAX4657ESA+T ideal for backup path activation in power-loss scenarios.
Can MAX4657ESA+T operate from a single +12V supply?
Yes, MAX4657ESA+T supports single-supply operation from +9V to +40V. With +12V applied to V+, GND to V− and GND, it delivers 10Ω max RON, 150mA continuous current, and rail-to-rail switching from 0V to +12V - verified per Electrical Characteristics table for single-supply conditions.
What is the maximum allowable voltage difference between V+ and V− for MAX4657ESA+T?
The absolute maximum V+ to V− rating for MAX4657ESA+T is ±44V. Operation within this 40V total range (e.g., V+ = +24V, V− = −16V) is permitted, provided each supply remains within its individual absolute max limits (V+ to GND ≤ +44V, V− to GND ≥ −44V).
Does MAX4657ESA+T require a separate logic supply (VL)?
No, MAX4657ESA+T does not require a VL pin or auxiliary logic supply. Its IN input is fully TTL/CMOS compatible across the full temperature range (−40°C to +85°C), accepting 0.8V/2.4V thresholds directly from standard microcontrollers or FPGAs without level shifting.
How does the exposed paddle feature apply to MAX4657ESA+T?
MAX4657ESA+T uses the standard SO-8 package (MS-012) without an exposed paddle (EP). Unlike TDFN-EP or µMAX-EP variants, this version relies on lead-frame thermal conduction; its 471mW continuous power dissipation rating at +70°C reflects SO-8 thermal limits, not EP-enhanced cooling.
