Product details
Overview
MAX4600EAE from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.25Ω max RON match between channels, and 0.3Ω max RON flatness over ±10V signal range, supporting reed relay replacement in automated test equipment.
For engineers reviewing the MAX4600EAE datasheet, MAX4600EAE pinout, MAX4600EAE application, or MAX4600EAE equivalent, key selection criteria include guaranteed dual-supply operation (±4.5V to ±20V), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), <2.5nA off-leakage at +85°C, and 16-pin SSOP packaging for space-constrained industrial signal conditioning designs.
Technical Context
The MAX4600EAE implements complementary MOSFET-based SPST switching architecture with independent digital control inputs (IN1, IN2) driving separate NC/NO configurations per channel. Its rail-to-rail analog signal handling supports input voltages from V− to V+, enabling full-range signal pass-through without clipping in bipolar or single-supply systems.
Internal protection diodes clamp signals exceeding V+ or V−, while guaranteed RON matching (≤0.25Ω) and flatness (≤0.3Ω) ensure minimal gain error and distortion in instrumentation multiplexing. Logic supply (VL) is decoupled from analog supplies (V+, V−), allowing mixed-voltage system integration with +5V logic and ±15V analog rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 1.25Ω max - ensures minimal voltage drop and power loss in high-current analog paths up to ±200mA continuous. |
| RON Match | 0.25Ω max - guarantees matched gain and phase response across dual channels for differential or ratiometric measurements. |
| RON Flatness | 0.3Ω max - maintains consistent attenuation and linearity over full ±10V analog signal swing. |
| Off-Leakage Current | 2.5nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports legacy industrial ±15V systems and modern wide-input power architectures. |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable TTL/CMOS compatibility with +12V single or ±15V dual supply configurations. |
| Turn-On/Off Time | 150ns / 200ns typical - enables fast multiplexing in data acquisition systems operating up to several MHz. |
Pinout & Package
MAX4600EAE is housed in a 16-pin SSOP package (5.3mm width, JEDEC MO-150 compliant) with exposed pad not present; thermal dissipation rated at 571mW at +70°C ambient (derated 7.1mW/°C above).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No-connect (N.C.) | Not internally connected; must be tied to GND or low-impedance node to improve off-isolation performance. |
| 2, 7 | COM1, COM2 | Analog common terminals - serve as bidirectional signal ports shared between NC and NO paths per channel. |
| 4 | V− | Negative analog supply - grounded for single-supply operation; sets lower rail for rail-to-rail signal handling. |
| 5 | GND | Digital/analog reference ground - provides return path for logic and supply currents; requires low-impedance layout. |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM when IN = 0; used for default-closed signal paths. |
| 11, 14 | COM1, COM2 | Duplicate COM pins - electrically identical to pins 2 and 7; provide layout flexibility and current sharing. |
| 12 | VL | Logic supply input - powers internal control circuitry; accepts +2.7V to +5.5V independent of analog supplies. |
| 13 | V+ | Positive analog supply - sets upper rail; supports up to +36V for high-voltage signal routing applications. |
| 1, 3, 6, 8, 10, 15 | N.C. | Unused pins - no internal connection; grounding reduces parasitic coupling and improves crosstalk rejection. |
| IN1, IN2 | Digital control inputs | TTL/CMOS-compatible logic inputs - drive respective switches; IN=0 closes NC path, IN=1 opens NC and closes NO path. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor output digitization and DAC output buffering. |
| Guaranteed RON matching | ≤0.25Ω max mismatch between channels - eliminates gain error in dual-channel instrumentation amplifiers and differential ADC front-ends. |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in manufacturing, field service, and bench-level test environments. |
| Low charge injection | 40pC typical - minimizes voltage glitch on sampled nodes, critical for precision sample-and-hold and switched-capacitor filter designs. |
| Off-isolation | −53dB typical - suppresses crosstalk between active and inactive channels in multi-signal routing applications. |

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 | 1.3Ω RON, ±15V supply only, 0.15Ω RON match, 16-TSSOP package | Limited to ±15V dual supply; lacks +4.5V–+36V single-supply flexibility of MAX4600EAE | Select when tighter RON matching is required and system operates strictly at ±15V. |

Compared with ADG1419BRUZ and TS5A3157DCKR, MAX4600EAE uniquely supports both wide single-supply (up to +36V) and dual-supply (±20V) operation while integrating NC/NO topology in one device-making it optimal for industrial ATE and telecom infrastructure requiring fail-safe routing and high-voltage tolerance.

FAQ
What is the maximum analog signal voltage range supported by the MAX4600EAE?
The MAX4600EAE supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of −44V to +44V across V+ and V−. In standard operation, it handles ±10V signals with guaranteed 0.3Ω RON flatness, and functions across full dual-supply ranges of ±4.5V to ±20V or single-supply ranges of +4.5V to +36V. This makes MAX4600EAE suitable for both industrial ±15V systems and high-voltage data acquisition front-ends.
How does the NC/NO configuration of the MAX4600EAE differ from the MAX4580 and MAX4590 variants?
The MAX4600EAE integrates one normally closed (NC) and one normally open (NO) SPST switch in a single 16-pin package, whereas MAX4580EAE contains two NC switches and MAX4590EAE contains two NO switches. This hybrid topology allows MAX4600EAE to implement fail-safe default paths (via NC) alongside on-demand signal connections (via NO), which is critical in applications like telecom ring detection or redundant sensor monitoring where continuity must be maintained during power loss or control failure.
Can the MAX4600EAE operate with different voltage levels on VL and the analog supplies?
Yes, the MAX4600EAE features independent VL (logic supply) and analog supplies (V+, V−), allowing VL to be set at +3.3V or +5V while V+ and V− operate at ±15V or +24V/0V. This separation enables seamless interfacing with modern low-voltage microcontrollers while preserving full analog signal swing. The logic inputs maintain TTL/CMOS thresholds regardless of analog rail voltages, ensuring reliable control without level shifters - a key advantage of MAX4600EAE in mixed-signal systems.
What is the thermal performance of the MAX4600EAE in its 16-pin SSOP package?
The MAX4600EAE in 16-pin SSOP has a power dissipation limit of 571mW at +70°C ambient, derating linearly at 7.1mW/°C above that temperature. Junction-to-ambient thermal resistance (θJA) is approximately 175°C/W. For continuous operation at full ±200mA load, board layout must include adequate copper pour on the GND plane and avoid enclosing the device in thermally restrictive enclosures. The MAX4600EAE's specified −40°C to +85°C operating range is validated under these thermal constraints.
Does the MAX4600EAE require external protection diodes for overvoltage conditions?
No - the MAX4600EAE includes internal ESD protection diodes on all analog pins (COM, NC, NO), clamping signals that exceed V+ or V−. However, if analog signals may transiently exceed the absolute maximum ratings (e.g., >+44V or <−44V), external series diodes are recommended per Maxim's Figure 1. These diodes reduce usable signal range by ~0.7V but preserve MAX4600EAE's low RON and leakage specs. Such protection is unnecessary for standard ±15V or +24V applications within datasheet limits.
