Product details
Overview
MAX4603EAE+ from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, 4.5V to 36V single-supply or ±4.5V to ±20V dual-supply operation, 2.5Ω max on-resistance, 0.5Ω max RON match, and rail-to-rail analog signal handling - used in audio-signal routing and reed-relay replacement where low distortion and high reliability are required.
For engineers reviewing the MAX4603EAE+ datasheet, MAX4603EAE+ pinout, MAX4603EAE+ application, or MAX4603EAE+ equivalent, this page delivers verified electrical specs, package mapping, functional pin roles, real-world use cases, and validated alternative parts for automatic test equipment, PBX systems, avionics signal switching, and industrial analog multiplexing.
Technical Context
The MAX4603EAE+ integrates four independent CMOS SPST switches in a single 16-pin SSOP package, with mixed NO/NC topology enabling flexible signal path control. Its logic inputs feature TTL/CMOS-compatible thresholds (0.8V/2.4V), supporting direct interface with +12V or ±15V systems without level-shifting.
It operates across –40°C to +85°C with guaranteed performance: on-resistance flatness ≤0.4Ω over ±10V signal range, off-leakage ≤0.5nA at +85°C, and turn-on/off times of 160ns/170ns (typ) at VCOM = 10V. Internal ESD protection exceeds 2000V per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths. |
| RON Match | 0.5Ω max between channels - enables matched gain/attenuation in differential or multi-channel routing. |
| RON Flatness | 0.4Ω max over ±10V - maintains consistent channel behavior across full signal swing. |
| Off-Leakage Current | 0.5nA max at +85°C - preserves signal integrity in high-impedance sensor or sample-hold circuits. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide industrial and test-equipment power architectures. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) - allows direct drive from microcontrollers or FPGAs without external buffers. |
| ESD Protection | >2000V HBM - enhances robustness in handling and board-level assembly environments. |
Pinout & Package
MAX4603EAE+ is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, footprint compatible with industry-standard 16-lead SSOP layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs determining NO/NC state per channel; active-high logic. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection points. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - connected to COM when IN = 0V. |
| 12 | VL | Logic supply input - decouples logic threshold reference from analog supplies. |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail signal handling. |
| 4 | V− | Negative analog supply - sets lower rail; tied to GND for single-supply operation. |
| 5 | GND | Ground reference for logic and substrate - requires low-impedance connection to minimize noise coupling. |
| 14, 11 | NO1, NO4 | Normally open analog terminals - connected to COM only when corresponding IN = high. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC configuration | Two NO and two NC switches enable fail-safe and redundant signal routing in safety-critical paths. |
| Rail-to-rail analog signal handling | Supports full-swing signals from V− to V+, eliminating clipping in ±15V or +12V instrumentation front-ends. |
| Guaranteed RON flatness | ≤0.4Ω variation across ±10V range ensures linear gain response in audio and measurement applications. |
| Low charge injection (20pC typ) | Minimizes voltage glitch at COM during switching - critical for sample-and-hold and data-acquisition systems. |
| High off-isolation (–56dB typ) | Suppresses crosstalk between inactive channels in multi-channel communication or test matrix systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1404BRUZ | 4-channel, 4.5Ω RON, ±15V supply, 16-TSSOP; higher RON, no mixed NO/NC topology. | Best suited for low-cost, non-critical multiplexing where channel matching is less stringent. | Select ADG1404BRUZ if system tolerates higher on-resistance and does not require fail-safe NC paths. |
| TS5A23157DGSR | 2-channel, 0.9Ω RON, +1.65V to +5.5V supply, 10-MSOP; lower voltage, dual-channel only, no NC option. | Targeted at portable, battery-powered signal routing - incompatible with industrial ±15V or +24V rails. | Choose TS5A23157DGSR only for low-voltage, space-constrained designs requiring ultra-low RON. |
Compared with MAX4603EAE+, ADG1404BRUZ offers broader temperature qualification but lacks the integrated NO/NC flexibility needed for fault-tolerant routing, while TS5A23157DGSR provides superior RON at the cost of supply voltage compatibility and channel count - making MAX4603EAE+ the optimal choice for industrial-grade, mixed-mode analog switching.

FAQ
What is the operating temperature range for MAX4603EAE+?
The MAX4603EAE+ is rated for operation from –40°C to +85°C, verified across all electrical parameters including on-resistance, leakage current, and switching speed. This extended industrial temperature grade ensures reliable performance in harsh environments such as factory automation controllers and airborne electronics enclosures where thermal cycling is frequent.
Does MAX4603EAE+ support single-supply operation?
Yes, MAX4603EAE+ supports single-supply operation from +4.5V to +36V. In this mode, V− is connected to GND, VL is supplied with +5V, and analog signals swing rail-to-rail from 0V to V+. The device maintains 2.5Ω max RON and 0.5nA max off-leakage at +85°C under single-supply conditions, as confirmed in the "Single +12V Supply" electrical characteristics table.
How is the NO/NC configuration implemented in MAX4603EAE+?
The MAX4603EAE+ implements two normally open (NO1, NO4) and two normally closed (NC2, NC3) switches. When IN1 = IN4 = low, NO1 and NO4 are disconnected from COM1/COM4; when IN2 = IN3 = low, NC2 and NC3 remain connected to COM2/COM3. This mixed topology is fixed per pinout - not configurable - and matches the functional diagram on page 1 of the datasheet.
What is the maximum analog signal voltage range supported by MAX4603EAE+?
MAX4603EAE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of –0.3V to +44V on V+ and +0.3V to –44V on V−. For ±15V dual-supply operation, the usable analog range is –15V to +15V; for +12V single-supply, it is 0V to +12V - both fully characterized and guaranteed in the datasheet's Electrical Characteristics tables.
Is MAX4603EAE+ pin-compatible with other MAX460x variants?
Yes, MAX4603EAE+ shares identical 16-pin SSOP pinout and footprint with MAX4601EAE+ and MAX4602EAE+, differing only in internal switch configuration (NC-only, NO-only, or mixed). All three support the same supply ranges, logic thresholds, and timing specs - enabling drop-in replacement in existing layouts when functional requirements change.
