Product details
Overview
MAX4658EUA+T from Maxim Integrated is a normally open (NO), single-pole/single-throw (SPST), high-current CMOS analog switch in an 8-pin µMAX package. It delivers 150mA continuous and 300mA peak switching current, 10Ω max on-resistance at ±15V, rail-to-rail signal handling, and 1nA max off-leakage at +25°C - enabling robust relay replacement in audio routing and redundant power-path control.
For engineers reviewing the MAX4658EUA+T datasheet, MAX4658EUA+T pinout, MAX4658EUA+T application, or MAX4658EUA+T equivalent, this page provides verified electrical specs, thermal derating data, truth table behavior, real-world leakage vs. temperature curves, and validated alternatives for high-voltage analog switching designs.
Technical Context
The MAX4658EUA+T implements a parallel N-channel/P-channel MOSFET switch architecture with proprietary body-drive sensing to eliminate the ~600mV voltage-drop limitation of standard CMOS switches. This enables full rail-to-rail conduction without parasitic diode turn-on, even under asymmetric dual-supply conditions (e.g., V+ = +24V, V− = −5V).
It operates across ±4.5V to ±20V dual supplies or +9V to +40V single supply, with guaranteed TTL/CMOS-compatible logic thresholds (VIH = 2.4V, VIL = 0.8V) and no VL bias requirement. Its 210MHz −3dB bandwidth and <200ns switching times support high-fidelity audio and broadband test-signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally open (NO) SPST analog switch - conducts only when IN = logic high. |
| On-Resistance (RON) | 10Ω max at ±15V supplies - ensures minimal insertion loss in 50Ω–600Ω signal paths. |
| Continuous Current | ±150mA - supports sustained load switching in PBX line cards and backup system selectors. |
| Peak Current | ±300mA (1ms, 10% duty cycle) - handles surge loads during hot-swap or fault-clearing events. |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves signal integrity in high-impedance sensor interfaces. |
| Supply Range | +9V to +40V (single) or ±4.5V to ±20V (dual) - accommodates industrial 24V DC and telecom ±15V rails. |
| Bandwidth | 210MHz −3dB - maintains fidelity for composite video, xDSL upstream signals, and RF test tones. |
Pinout & Package
MAX4658EUA+T uses the 8-pin µMAX package (3.0mm × 3.0mm, 0.5mm pitch), with exposed paddle (EP) that must be connected to V+ for thermal performance and ESD robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 COM | Analog Switch Common | Output node - connects to load; bidirectional conduction path when switch is ON. |
| 2, 5 N.C. | No Internal Connection | Unbonded pins - must remain unconnected; no internal circuitry or thermal path. |
| 3 GND | Ground Reference | Logic ground return; not tied to analog signal reference - requires separate grounding strategy. |
| 4 V+ | Positive Supply Input | Bias for P-channel device and EP connection point; sets upper analog signal limit. |
| 6 IN | Digital Control Input | TTL/CMOS-compatible enable - logic high turns switch ON (COM ↔ NO); no pull-up/down required. |
| 7 V− | Negative Supply Input | Bias for N-channel device; defines lower analog signal limit and enables bipolar operation. |
| 8 NO | Analog Switch Normally Open | Input node - connects to source; only conductive to COM when IN = high. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog voltages from V− to V+ - eliminates level-shifting in ±12V audio or 24V industrial I/O. |
| 1Ω max RON flatness | Ensures consistent gain and THD across full signal swing - critical for low-distortion audio routing. |
| No VL bias required | Reduces BOM count and layout complexity - logic interface powered directly from V+ or local 3.3V/5V rail. |
| 25pF off-capacitance | Minimizes crosstalk and feedthrough in multi-channel systems - verified at 1MHz per Figure 6. |
| Charge injection ≤23pC | Prevents glitch-induced errors in precision sampling circuits - measured with 1nF load per Figure 4. |
Applications
| Audio Signal Routing | Redundant Power Path Selection |
|---|---|
Use Scenario: Selecting between primary and backup audio sources in PC multimedia boards or studio mixers. IC Role / Device Role / Timing Role: SPST analog switch controlling signal path continuity with sub-200ns switching and <0.007% THD. Use Value: Enables silent, pop-free source switching without external muting circuitry or timing delays. | Use Scenario: Automatically engaging backup DC power in telecom line cards upon main supply failure.

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+T | Same package and pinout; higher 300mA continuous current rating (vs. 150mA); 10Ω RON identical. | Preferred where sustained load current exceeds 150mA - e.g., driving multiple parallel loads or low-Z speakers. | Select MAX4656EUA+T only if design requires >150mA continuous conduction; otherwise MAX4658EUA+T offers better thermal efficiency at lower current. |
| ADG1419BRMZ-REEL7 | 12Ω RON max, ±15V supply, 175mA continuous, 300mA peak; 16-lead LFCSP, not pin-compatible. | Offers integrated fault protection and higher ESD rating (±4kV HBM); suited for harsh industrial environments. | Choose ADG1419BRMZ-REEL7 when overvoltage tolerance or system-level fault resilience is prioritized over footprint and pin compatibility. |
Compared with MAX4656EUA+T, the MAX4658EUA+T trades 2× continuous current capacity for lower power dissipation and improved thermal margin in µMAX packages - making it optimal for space-constrained, thermally sensitive audio and telecom modules where 150mA suffices.

FAQ
What is the maximum allowable voltage difference between V+ and V− for MAX4658EUA+T?
The MAX4658EUA+T supports a maximum V+ to V− differential of 44V, as specified in Absolute Maximum Ratings. Operation within ±4.5V to ±20V dual supplies (≤40V differential) is fully characterized and guaranteed across −40°C to +85°C. Exceeding 44V risks permanent damage, regardless of individual rail values.
Does MAX4658EUA+T require a separate logic supply (VL)?
No, the MAX4658EUA+T does not require a VL pin or separate logic supply. Its digital input (IN) is TTL/CMOS compatible and operates directly from the same V+ supply or an independent 3.3V/5V rail - simplifying power architecture and reducing component count in multi-rail systems.
Can MAX4658EUA+T switch signals beyond its supply rails?
No, the MAX4658EUA+T cannot safely switch signals beyond its V+ and V− rails. Inputs exceeding these limits forward-bias internal ESD diodes, risking latch-up or damage unless external clamping is implemented. The device is rated for rail-to-rail analog signals only - i.e., from V− to V+ - with guaranteed performance across that range.
What is the thermal derating for MAX4658EUA+T in the µMAX package?
The MAX4658EUA+T in the 8-pin µMAX package has a continuous power dissipation limit of 362mW at TA = +70°C, derating linearly at 4.50mW/°C above +70°C. At +85°C ambient, usable power drops to 294.5mW - requiring careful PCB copper area allocation and potential heatsinking for high-current, high-duty-cycle operation.
How does the charge injection specification of MAX4658EUA+T impact precision sampling circuits?
The MAX4658EUA+T exhibits ≤23pC charge injection (typical 1pC) when toggling, measured with 1nF load. In precision sampling applications, this induces ≤23mV glitch on a 1nF hold capacitor - manageable with proper sample-and-hold timing, guard traces, and low-impedance drivers, but requiring verification against target resolution (e.g., ≥12-bit systems).
