Product details
Overview
MAX4602CAE+T from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with four normally open (NO) channels, 2.5Ω maximum on-resistance, ±15V dual-supply or +12V single-supply operation, and rail-to-rail analog signal handling-ideal for reed relay replacement in automated test equipment and audio-signal routing.
For engineers reviewing the MAX4602CAE+T datasheet, MAX4602CAE+T pinout, MAX4602CAE+T application, or MAX4602CAE+T equivalent, key selection criteria include guaranteed RON match (≤0.5Ω), low off-leakage (≤2.5nA at +85°C), TTL/CMOS-compatible logic thresholds, and 16-pin SSOP package compatibility with space-constrained industrial control and communication systems.
Technical Context
The MAX4602CAE+T implements CMOS-based SPST switching architecture with independent digital control inputs per channel, enabling precise ON/OFF state selection without inter-channel coupling. Its internal charge-pump–free design supports true rail-to-rail analog voltage swing from V− to V+, with logic inputs referenced to VL and compatible with 0.8V/2.4V TTL/CMOS thresholds.
It operates across dual supplies (±4.5V to ±20V) or single supply (+4.5V to +36V), with guaranteed performance over 0°C to +70°C. Dynamic characteristics include 160ns typical turn-on time and −56dB off-isolation at 1MHz, optimized for low-distortion signal routing in precision instrumentation and avionics interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss in signal paths up to ±10V analog swing |
| RON Match Between Channels | 0.5Ω max - enables matched gain/attenuation in multi-channel instrumentation and balanced audio routing |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sensor front-ends and sample-hold circuits |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports legacy ±15V industrial rails and modern +12V embedded systems |
| Logic Input Thresholds | 0.8V low / 2.4V high - guarantees direct interface with standard TTL/CMOS microcontrollers without level-shifting |
| Turn-On/Off Time | 160ns / 190ns typical - suitable for multiplexing at >1MHz sampling rates in data acquisition systems |
| ESD Protection | >2000V HBM - enhances robustness during board handling and system integration in factory environments |
Pinout & Package
MAX4602CAE+T is housed in a 16-pin shrink small-outline package (SSOP), 5.3mm × 6.2mm body, 0.65mm lead pitch, JEDEC MO-153 compliant, with exposed pad not electrically connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-high logic turns corresponding NO switch ON; no internal pull-up/down |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source; current path when switch is closed |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - only conduct when respective INx = high; isolated otherwise |
| 4 | V− | Negative analog supply - must be tied to GND for single-supply operation; sets lower analog rail |
| 5 | GND | Digital/analog ground reference - shared return for logic and analog sections; requires low-impedance layout |
| 12 | VL | Logic supply input - accepts 2.7V to 5.5V; decouples logic threshold from analog supply rails |
| 13 | V+ | Positive analog supply - defines upper analog rail; supports up to +36V or +20V in dual mode |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous DC–10MHz signals from V− to V+ without clipping or distortion |
| Guaranteed RON flatness | 0.5Ω max variation over full signal range - maintains consistent gain in variable-gain amplifier paths |
| Low charge injection (20pC typ) | Minimizes voltage glitch at COM node during switching - critical for precision sample-and-hold and ADC front-ends |
| High off-isolation (−56dB at 1MHz) | Reduces crosstalk between active and inactive channels in multi-signal routing applications |
| TTL/CMOS-compatible inputs | Eliminates need for external level shifters when interfacing with FPGA I/O banks or MCU GPIOs |
Applications
| Reed Relay Replacement | Audio-Signal Routing |
|---|---|
Use Scenario: Replacing electromechanical relays in automatic test equipment (ATE) fixture boards requiring >1M cycle life and sub-ms switching. IC Role / Device Role: Quad SPST analog switch providing solid-state isolation and conduction paths for DUT signal stimulus/response routing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 4-channel SPST, 1.8Ω RON, ±15V supply, but requires VL = V+ and lacks separate logic supply pin | Better RON but less flexible supply configuration; no independent VL simplifies BOM but limits mixed-voltage logic interfacing | Prefer ADG1412BRUZ when lowest on-resistance is critical and system uses same voltage for analog and logic rails |
| TS5A3157DCUR | Single-channel SPDT, 0.75Ω RON, +1.65V to +5.5V supply only, no dual-supply support | Lower voltage operation and smaller 6-pin package, but not quad-channel and incompatible with ±15V industrial systems | Choose TS5A3157DCUR for battery-powered portable gear with 3.3V logic and no negative rail requirement |
Compared with ADG1412BRUZ and TS5A3157DCUR, the MAX4602CAE+T uniquely balances quad-channel density, wide supply flexibility (±4.5V to ±20V or +4.5V to +36V), independent VL pin for mixed-voltage designs, and guaranteed RON matching-making it optimal for industrial ATE and communications infrastructure where reliability and configurability outweigh marginal RON reduction.

FAQ
What is the operating temperature range for MAX4602CAE+T?
The MAX4602CAE+T is specified for commercial-grade operation from 0°C to +70°C. This temperature range is validated per the device's ordering code 'CAE', which denotes the 0°C to +70°C ambient specification. The MAX4602CAE+T does not meet extended industrial (−40°C to +85°C) requirements-those are fulfilled by the MAX4602EAE+T variant. Thermal derating applies above +70°C per the 7.1mW/°C power dissipation curve for the 16-pin SSOP package.
Can MAX4602CAE+T operate from a single +5V supply?
No, the MAX4602CAE+T cannot operate reliably from a single +5V supply. Its absolute minimum single-supply voltage is +4.5V, but electrical specifications-including 2.5Ω max RON and 0.8V/2.4V logic thresholds-are guaranteed only from +12V (single) or ±15V (dual). At +5V, RON rises significantly (>10Ω), logic thresholds become marginal, and leakage increases beyond datasheet limits. For +5V systems, consider the MAX4617 or similar low-voltage optimized switches.
Does MAX4602CAE+T require external protection diodes on V+ and V− pins?
No, external protection diodes are not required for normal operation of the MAX4602CAE+T. Internal ESD protection diodes are present on all pins, and the device meets >2000V HBM. However, if power-supply sequencing cannot be controlled (e.g., V− powered before V+), external series diodes may be added per Figure 1 in the datasheet to prevent latch-up-though this reduces usable analog signal range by ~1.4V and is not recommended for single-supply use.
How is the logic supply (VL) pin used in MAX4602CAE+T?
The VL pin on the MAX4602CAE+T sets the reference voltage for logic input thresholds (0.8V low / 2.4V high), decoupling them from the analog supply rails. It accepts 2.7V to 5.5V and must be bypassed with a 0.1µF capacitor to GND. When VL = 5V, the device accepts standard 5V TTL/CMOS logic; when VL = 3.3V, it correctly interprets 3.3V logic levels-even if V+ = +15V or V− = −15V. This enables mixed-voltage system interfacing without level shifters.
Is MAX4602CAE+T pin-compatible with other MAX460x variants like MAX4601CAE+T?
Yes, the MAX4602CAE+T is pin-compatible with MAX4601CAE+T and MAX4603CAE+T in the same 16-pin SSOP package. All share identical pinout, supply connections, logic interface, and thermal characteristics. The only functional difference is switch configuration: MAX4601CAE+T has four normally closed (NC) switches, MAX4602CAE+T has four normally open (NO), and MAX4603CAE+T has two NC + two NO. No PCB redesign is needed when substituting within the same temperature grade and package.
