Product details
Overview
The MAX4580EAE+T from Maxim Integrated is a dual SPST normally closed (NC) CMOS analog switch with 1.25Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail analog signal handling up to ±10V. It delivers matched on-resistance (≤0.25Ω), flat on-resistance (≤0.3Ω), and <2.5nA off-leakage at +85°C, making it suitable for precision automatic test equipment and reed relay replacement in communication systems.
For engineers reviewing the MAX4580EAE+T datasheet, MAX4580EAE+T pinout, MAX4580EAE+T application, or MAX4580EAE+T equivalent, key selection criteria include guaranteed RON matching across channels, TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), low charge injection (40pC), and ESD protection >2kV - all validated over –40°C to +85°C.
Technical Context
This device implements two independent NC-configured transmission gates using high-voltage CMOS process technology, enabling bidirectional rail-to-rail analog switching without signal clipping. Its control architecture accepts TTL/CMOS logic levels regardless of supply configuration, with dedicated VL pin for logic-level referencing separate from analog supplies.
Internal protection diodes clamp input signals exceeding V+ or V–, and absolute maximum ratings define safe operating limits: V+ to GND ≤ +44V, V– to GND ≥ –44V, and continuous COM/NO/NC current ≤ ±200mA. On-resistance remains stable across temperature (–40°C to +85°C) and analog signal voltage (±10V), with flatness specified over full signal range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to ±10V analog signals. |
| RON Match | 0.25Ω max - guarantees consistent gain/attenuation across dual channels in differential or parallel configurations. |
| RON Flatness | 0.3Ω max - maintains linear signal integrity over full ±10V input range, critical for audio and instrumentation. |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sample-and-hold or sensor multiplexing. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, telecom, and test equipment power architectures. |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable TTL/CMOS compatibility without level-shifting when V+ = +12V or ±15V. |
| Charge Injection | 40pC - minimizes voltage glitch on sampled nodes, essential for precision ADC front-ends and data acquisition. |
Pinout & Package
MAX4580EAE+T is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, 5.3mm body width, and JEDEC MO-150 compliance. Pin 1 is marked by a dot; pins 1, 3, 6, 8, 10, and 15 are no-connect (N.C.) and must be tied to GND or low-impedance point to improve isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Not internally connected; grounding improves off-isolation and reduces crosstalk. |
| 2, 7 | COM1, COM2 | Common analog terminals - bidirectional signal path entry/exit points for each NC switch. |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower rail for rail-to-rail signal swing. |
| 5 | GND | Analog/digital ground reference - common return for supplies, logic, and signal paths. |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM when IN = low; open when IN = high. |
| 11, 14 | COM1, COM2 | Duplicate COM pins - electrically identical to pins 2 and 7; used for layout routing flexibility. |
| 12 | VL | Logic supply input - references IN logic thresholds independently of analog supplies, enabling mixed-voltage control. |
| 13 | V+ | Positive analog supply - defines upper rail for rail-to-rail analog signal handling up to V+ − 0.3V. |
| 1, 3, 6, 8, 10, 15 | N.C. | Not internally connected - connect to GND to reduce parasitic coupling and improve channel-to-channel isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from V− to V+, enabling full dynamic range utilization in ±15V or +12V systems without clipping. |
| Guaranteed RON match | ≤0.25Ω difference between channels - eliminates gain mismatch in dual-path instrumentation or balanced signal routing. |
| TTL/CMOS-compatible inputs | +0.8V low / +2.4V high thresholds - allows direct interface to microcontrollers and FPGAs without external level shifters. |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in manufacturing, test, and field environments with static-prone handling. |
| Low charge injection | 40pC - reduces settling error in sampling circuits, improving accuracy in multichannel data acquisition systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | 1.8Ω max RON, ±15V supply only, no single-supply support; 16-lead TSSOP package. | Higher RON limits use in <10mV precision applications; lacks VL pin for independent logic referencing. | Select when ±15V-only operation suffices and ADI ecosystem integration is prioritized over leakage or flatness specs. |
| TS5A23157DGSR | 0.9Ω max RON, +1.65V to +5.5V supply only; no dual-supply capability; 10-pin VSSOP package. | Restricted to low-voltage logic systems; cannot handle ±10V rail-to-rail signals or industrial supply rails. | Choose only for battery-powered portable instruments requiring ultra-low quiescent current (<1µA), not for industrial ATE. |
Compared with ADG1419BRUZ and TS5A23157DGSR, the MAX4580EAE+T uniquely supports both wide-range dual and single supplies, guarantees RON flatness ≤0.3Ω over ±10V, and delivers <2.5nA off-leakage at +85°C - making it the only option qualified for high-accuracy, high-reliability industrial and telecom signal routing.

FAQ
What is the maximum analog signal voltage the MAX4580EAE+T can switch?
The MAX4580EAE+T supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings allowing V+ up to +44V and V− down to –44V. In standard operation with ±15V supplies, it reliably switches ±10V signals without clipping or distortion, as confirmed by RON flatness ≤0.3Ω over that range.
Does the MAX4580EAE+T require external level-shifting for TTL/CMOS logic control?
No. The MAX4580EAE+T features built-in TTL/CMOS-compatible logic thresholds (+0.8V low, +2.4V high) that function correctly with +12V single supply or ±15V dual supplies. Its dedicated VL pin allows logic referencing independent of analog supplies, eliminating need for external level shifters in mixed-voltage systems.
How does the MAX4580EAE+T ensure signal integrity in precision measurement applications?
The MAX4580EAE+T ensures signal integrity via 0.25Ω max RON matching between channels, 0.3Ω max RON flatness over ±10V, and 40pC charge injection - all tested across –40°C to +85°C. These parameters minimize gain error, harmonic distortion, and settling glitches in 16-bit+ data acquisition and calibration systems.
Can the MAX4580EAE+T operate from a single +5V supply?
No. The MAX4580EAE+T requires minimum +4.5V single supply or ±4.5V dual supplies. At +5V, its RON increases significantly (typical 3Ω), and rail-to-rail operation is compromised. For +5V systems, consider the MAX4580's lower-voltage counterparts like the MAX4617, but note they lack the same leakage and flatness specs.
What is the purpose of the VL pin on the MAX4580EAE+T?
The VL pin on the MAX4580EAE+T provides an independent logic supply reference, decoupling digital input thresholds from analog supply rails. This allows clean TTL/CMOS interfacing even when V+ and V− are at high voltages (e.g., ±15V), preventing logic misreads due to supply noise or asymmetry - a feature absent in most competing analog switches.
