Product details
Overview
MAX4603EPE+ from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, 2.5Ω max on-resistance, ±15V dual-supply or +12V single-supply operation, and rail-to-rail signal handling-used in audio-signal routing, test equipment, and PBX systems where low distortion and mechanical relay replacement are critical.
For engineers reviewing the MAX4603EPE+ datasheet, MAX4603EPE+ pinout, MAX4603EPE+ application, or MAX4603EPE+ equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases, and validated alternative parts for analog switching design-in and BOM optimization.
Technical Context
The MAX4603EPE+ implements CMOS-based transmission-gate architecture with independent digital control inputs per switch channel. Its dual- or single-supply operation supports ±4.5V to ±20V or +4.5V to +36V, and logic inputs feature TTL/CMOS-compatible thresholds (0.8V low / 2.4V high) at VL = 5V.
Each channel guarantees matched on-resistance (≤0.5Ω max ΔRON) and flat on-resistance (≤0.4Ω max flatness) over the full signal range, enabling precision signal routing without gain error or harmonic distortion. Off-isolation exceeds –56dB at 1MHz, and charge injection is limited to 20pC typical.
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. |
| RON Match (ΔRON) | 0.5Ω max - enables precise channel-to-channel signal balancing in multiplexer or differential routing. |
| Rail-to-Rail Signal Range | Supports analog signals from V– to V+ - eliminates clipping in wide-dynamic-range audio or sensor interfaces. |
| Off-Leakage Current | 0.5nA max at +85°C - preserves signal integrity in high-impedance sampling circuits and battery-powered systems. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - accommodates industrial, telecom, and avionics power architectures. |
| Turn-On/Off Time | 160ns / 170ns typical - supports fast-switching applications like automated test sequencing and digital audio routing. |
| ESD Protection | >2000V HBM - reduces need for external protection in board-level ESD-prone environments. |
Pinout & Package
MAX4603EPE+ is housed in a 16-pin plastic DIP package (0.3-inch width), through-hole mountable, rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic drives NO/NC state per channel. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection points. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct when INx = 0V (MAX4603 uses NC1, NC4). |
| 12 | VL | Logic supply input - decouples digital threshold reference from analog supplies (typically 5V). |
| 4 | V– | Negative analog supply - tied to GND for single-supply operation. |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail analog signal handling. |
| 5 | GND | Ground reference for logic and substrate - must be low-impedance for leakage-sensitive designs. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | 0.4Ω max variation across ±10V signal range - prevents amplitude-dependent distortion in audio and instrumentation. |
| TTL/CMOS-compatible inputs | 0.8V/2.4V thresholds with VL = 5V - allows direct interfacing to microcontrollers and FPGAs without level-shifting. |
| Low charge injection | 20pC typical - minimizes voltage glitches at COM nodes during switching, critical for sample-and-hold accuracy. |
| High off-isolation | –56dB at 1MHz - suppresses crosstalk between active and inactive channels in dense analog routing. |
| Robust supply flexibility | Operates from ±4.5V to ±20V or +4.5V to +36V - simplifies system-level power architecture across industrial and telecom platforms. |
Applications
| Audio-Signal Routing | Automatic Test Equipment (ATE) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4603EWE+ | Same die, 16-pin wide SO package - surface-mount, smaller footprint, higher thermal dissipation. | Preferred for space-constrained PCBs or reflow assembly; not suitable for through-hole prototyping. | Select MAX4603EWE+ when board area or automated assembly is prioritized over manual soldering or socket compatibility. |
| ADG465BRZ | 2.8Ω max RON, ±15V supply, but only dual NO configuration - no NC functionality; 16-lead SOIC. | Lacks NC/NO mixing; requires redesign if NC path redundancy is essential in current layout. | Choose ADG465BRZ only if strictly NO-only routing suffices and Maxim's mixed topology is unnecessary. |
Compared with MAX4603EPE+, MAX4603EWE+ offers identical electrical performance in a surface-mount package, while ADG465BRZ provides similar on-resistance and supply range but omits the dual NO/dual NC flexibility critical for fail-safe or bidirectional signal path designs.

FAQ
What is the maximum supply voltage rating for MAX4603EPE+?
The MAX4603EPE+ supports absolute maximum ratings of V+ to GND = –0.3V to +44V and V– to GND = +0.3V to –44V. For reliable operation, use within the recommended ranges: ±4.5V to ±20V (dual supply) or +4.5V to +36V (single supply). Exceeding these may cause permanent damage, and the device is not guaranteed to function outside its specified operating conditions.
Does MAX4603EPE+ support rail-to-rail analog signal switching?
Yes, MAX4603EPE+ fully supports rail-to-rail analog signal handling - signals from V– to V+ pass through the switch with minimal distortion. This is confirmed in both the General Description and Electrical Characteristics tables, where input voltage range is specified as (V–) to (V+) across all operating temperatures and supply configurations.
How many normally open and normally closed switches does MAX4603EPE+ contain?
MAX4603EPE+ contains exactly two normally open (NO) switches and two normally closed (NC) switches - a unique configuration among the MAX460x series. Pin diagrams and truth tables in the datasheet confirm IN1/IN4 control NO1/NO4, while IN2/IN3 control NC2/NC3, enabling simultaneous break-before-make or make-before-break routing schemes.
What is the on-resistance matching specification for MAX4603EPE+?
MAX4603EPE+ guarantees on-resistance matching (ΔRON) of ≤0.5Ω maximum between any two channels under all operating conditions. This parameter is explicitly tested and specified in the Electrical Characteristics table for both dual- and single-supply operation, ensuring consistent gain and phase response across switched paths.
Is MAX4603EPE+ pin-compatible with other devices in the MAX460x family?
Yes, MAX4603EPE+ shares identical pinout and package dimensions with MAX4601EPE+ and MAX4602EPE+ - all are 16-pin plastic DIP devices with identical terminal assignments. However, internal switch configuration differs: MAX4601 is quad NC, MAX4602 is quad NO, and MAX4603 is dual NO/dual NC. Swapping requires logic-level and functional verification.
