Product details
Overview
MAX4602CAE+ from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω maximum on-resistance, 0.4Ω typical on-resistance match between channels, and 0.4Ω typical on-resistance flatness over ±10V signal range. Operating from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies, it serves as a solid-state replacement for reed relays in automated test equipment.
For engineers reviewing the MAX4602CAE+ datasheet, MAX4602CAE+ pinout, MAX4602CAE+ application, or MAX4602CAE+ equivalent, key selection criteria include guaranteed RON matching, low charge injection (20pC), TTL/CMOS-compatible logic thresholds, and −56dB off-isolation at 1MHz - all validated across 0°C to +70°C industrial temperature range in 16-pin SSOP package.
Technical Context
The MAX4602CAE+ implements CMOS transmission-gate architecture with matched P- and N-channel MOSFETs per switch, enabling rail-to-rail analog conduction without body-diode limitations. Its control logic accepts 0.8V/2.4V thresholds independent of supply voltage, supporting interoperability with both +12V single-supply and ±15V dual-supply systems.
All four switches share common V+, V−, VL, and GND connections while maintaining channel-to-channel isolation. The device guarantees monotonic RON flatness ≤0.4Ω over full analog signal swing (±10V), ensuring minimal THD in audio and instrumentation signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures <10mV drop at 10mA signal current, critical for precision sensor multiplexing |
| RON Match | 0.4Ω max - enables <0.1% gain error in differential channel switching applications |
| RON Flatness | 0.4Ω max over ±10V - maintains consistent signal attenuation across full input range |
| Off-Leakage Current | 0.5nA max at +85°C - prevents DC offset drift in high-impedance measurement circuits |
| Charge Injection | 20pC typical - limits voltage glitch to <200µV on 100pF sampling capacitor |
| Off-Isolation | −56dB at 1MHz - suppresses crosstalk between active and inactive signal paths |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports legacy industrial and modern wide-range systems |
Pinout & Package
MAX4602CAE+ is housed in a 16-pin shrink small-outline package (SSOP) with 0.65mm lead pitch, JEDEC MO-137AC compliant, footprint compatible with industry-standard 16-SOIC but 30% smaller area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; TTL/CMOS-compatible with 0.8V/2.4V thresholds |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; bidirectional, rail-to-rail capable |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs; connect to COM only when IN = HIGH |
| 4 | V− | Negative analog supply; tied to GND for single-supply operation |
| 5 | GND | Digital/analog ground reference; separate from power return path in mixed-signal layouts |
| 12 | VL | Logic supply input; decoupled 5V source required for stable threshold behavior |
| 13 | V+ | Positive analog supply; must be powered before V− and logic inputs per sequencing guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping or distortion, enabling direct interface with op-amp outputs |
| Guaranteed RON match | 0.4Ω max channel-to-channel variation ensures balanced performance in differential or multi-channel mux designs |
| ESD protection | >2000V per Method 3015.7 - eliminates need for external TVS diodes in board-level ESD zones |
| TTL/CMOS logic compatibility | Fixed 0.8V/2.4V thresholds function reliably across full supply range, simplifying interface with FPGA/CPLD I/O |
| Low charge injection | 20pC typical - minimizes sampling errors in data acquisition systems using switched-capacitor front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRUZ | Single 4-channel SPST; 4.5Ω RON, −50dB off-isolation, operates up to +36V but no dual-supply support | Lacks dual-supply capability and rail-to-rail performance; suitable only for single-supply systems with relaxed RON tolerance | Select when cost sensitivity outweighs need for ultra-low RON and dual-supply flexibility |
| TS5A3157DCKR | Single 4-channel SPST; 0.75Ω RON, but limited to +5.5V max supply and ±5.5V signal range | Cannot handle industrial ±15V or telecom ±20V rails; unsuitable for high-voltage signal routing | Prefer only in battery-powered portable audio or low-voltage sensor interfaces |
Compared with ADG465BRUZ and TS5A3157DCKR, the MAX4602CAE+ uniquely combines 2.5Ω RON, ±20V dual-supply operation, and rail-to-rail signal handling - making it the only option among the three qualified for high-fidelity ATE and telecom infrastructure applications requiring wide dynamic range and robust voltage tolerance.

FAQ
What is the operating temperature range for MAX4602CAE+?
The MAX4602CAE+ is specified for operation from 0°C to +70°C. This commercial-grade temperature range aligns with its CAE suffix designation and is validated across all electrical parameters including RON, leakage, and switching times. For extended industrial use, the MAX4602EAE+ variant supports −40°C to +85°C.
Can MAX4602CAE+ operate from a single +5V supply?
No, the MAX4602CAE+ requires a minimum +4.5V single supply, but +5V operation is not recommended due to insufficient headroom for guaranteed RON performance and logic threshold margins. At +5V, RON rises significantly and may exceed 2.5Ω; the device is optimized for +12V or higher single supplies or ±15V dual supplies.
Does MAX4602CAE+ require an external logic supply (VL)?
Yes, the MAX4602CAE+ requires a dedicated 5V logic supply connected to pin 12 (VL). This separate rail ensures stable 0.8V/2.4V logic thresholds regardless of analog supply variations. Using V+ for VL degrades noise immunity and may cause erratic switching behavior, especially near supply limits.
How does MAX4602CAE+ handle power-supply sequencing?
The MAX4602CAE+ mandates strict sequencing: V+ must be applied first, then V−, followed by VL and logic inputs. Violating this order risks exceeding absolute maximum ratings on internal protection diodes. If sequencing cannot be guaranteed, external series diodes (as shown in Figure 1 of the datasheet) are required - though they reduce usable analog signal range by ~1.4V.
Is MAX4602CAE+ pin-compatible with MAX4601CAE+ or MAX4603CAE+?
Yes, MAX4602CAE+, MAX4601CAE+, and MAX4603CAE+ share identical 16-pin SSOP footprints and pinouts. The only functional difference is switch configuration: MAX4602CAE+ has four NO switches, MAX4601CAE+ has four NC switches, and MAX4603CAE+ has two NO + two NC. PCB layout can be reused across all three variants with only firmware control logic changes.
