Product details
Overview
MAX4603CPE+ 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 PBX audio routing and automatic test equipment for low-distortion signal switching.
For engineers reviewing the MAX4603CPE+ datasheet, MAX4603CPE+ pinout, MAX4603CPE+ application, or MAX4603CPE+ equivalent, key selection criteria include guaranteed RON match (≤0.5Ω), off-leakage ≤0.5nA at +85°C, TTL/CMOS-compatible logic thresholds, and 16-pin PDIP package compatibility with legacy through-hole layouts.
Technical Context
The MAX4603CPE+ implements four independent CMOS transmission gates controlled by digital inputs with fixed logic polarity per channel pair: IN1/IN4 control NC switches (closed at logic low), while IN2/IN3 control NO switches (closed at logic high). All switches share common analog supply pins (V+, V−, GND) and a separate logic supply (VL).
Its architecture guarantees matched on-resistance across channels (ΔRON ≤ 0.5Ω) and flat RON (≤0.5Ω variation) over the full ±10V signal range, enabling precision multiplexing without gain error or harmonic distortion in audio and instrumentation paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss at 10mA signal current |
| RON Match | 0.5Ω max - enables accurate channel-to-channel signal amplitude tracking in differential or multi-path systems |
| RON Flatness | 0.5Ω max over ±10V - maintains consistent gain and linearity across full analog input range |
| Off-Leakage Current | 0.5nA max at +85°C - preserves high-impedance node integrity in sample-and-hold or sensor front-ends |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, telecom, and avionics rails without level-shifting |
| Logic Thresholds | VIN_H = 2.4V, VIN_L = 0.8V - ensures reliable TTL/CMOS interfacing with +12V or ±15V supplies |
| Turn-On/Off Time | tON = 250ns, tOFF = 350ns (typ.) - suitable for <1MHz multiplexing in data acquisition and relay replacement |
Pinout & Package
MAX4603CPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin 1 is top-left corner, with notch or dot marking orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs: IN1/IN4 drive NC switches; IN2/IN3 drive NO switches |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path entry/exit points |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - connected to COM when IN = low |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation |
| 5 | GND | Ground reference for analog and logic circuits |
| 12 | VL | Logic supply input - accepts 5V for TTL/CMOS compatibility |
| 13 | V+ | Positive analog supply - supports up to +36V or ±20V dual rails |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports ±10V signals with full on-state conduction - eliminates clipping in audio and sensor interfaces |
| Guaranteed RON match and flatness | 0.5Ω max mismatch and variation - enables precision gain-matched switching in instrumentation amplifiers |
| TTL/CMOS-compatible logic inputs | Fixed 0.8V/2.4V thresholds - allows direct interface to microcontrollers and FPGAs without external level shifters |
| ESD protection >2000V | Per Method 3015.7 - reduces need for external transient suppression in field-deployed test equipment |
| Low charge injection (20pC typ.) | Minimizes voltage glitch on high-impedance nodes - critical for sample-and-hold and ADC front-ends |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4603EPE+ | Extended temperature range (−40°C to +85°C) vs. C-grade (0°C to +70°C); identical pinout and electrical specs | Suitable for industrial or automotive environments requiring wider thermal margin | Select MAX4603EPE+ when operating ambient exceeds +70°C or requires AEC-Q200 alignment |
| ADG465BRZ | Single-supply only (+3V to +16.5V); 4.5Ω max RON; no dual-supply capability; SOIC-16 package | Better suited for low-voltage portable systems but lacks ±15V robustness for telecom/industrial use | Choose ADG465BRZ only if system operates strictly below +16.5V and does not require negative rail support |
Compared with MAX4603CPE+, MAX4603EPE+ offers identical functionality with extended temperature qualification, while ADG465BRZ trades dual-supply flexibility and lower RON for lower voltage operation and different package footprint-making MAX4603CPE+ optimal for legacy through-hole designs needing rail-to-rail ±15V switching.

FAQ
What is the maximum supply voltage rating for MAX4603CPE+?
The MAX4603CPE+ supports absolute maximum analog supply ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For continuous operation, the recommended dual-supply range is ±4.5V to ±20V, and single-supply range is +4.5V to +36V. Exceeding these limits risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does MAX4603CPE+ support rail-to-rail analog signal switching?
Yes, MAX4603CPE+ supports rail-to-rail analog signal switching - meaning it can pass signals from V− to V+ without clipping. This is explicitly guaranteed in the General Description and Electrical Characteristics sections, with verified operation over ±10V signal ranges under both dual- and single-supply conditions.
How many normally open and normally closed switches does MAX4603CPE+ contain?
MAX4603CPE+ contains two normally open (NO) switches and two normally closed (NC) switches. This configuration is defined in the General Description and confirmed in the Pin Configurations diagram, where IN2/IN3 control NO1/NO4 and IN1/IN4 control NC1/NC2 respectively.
What is the typical on-resistance flatness specification for MAX4603CPE+?
The typical on-resistance flatness for MAX4603CPE+ is 0.4Ω (max 0.5Ω), defined as the difference between maximum and minimum RON measured across the specified analog signal range (±10V). This value is documented in the Electrical Characteristics tables for both dual- and single-supply conditions and ensures consistent gain in precision analog paths.
Is MAX4603CPE+ pin-compatible with other devices in the MAX460x family?
Yes, MAX4603CPE+ is pin-compatible with MAX4601CPE+ and MAX4602CPE+ - all share identical 16-pin PDIP pinout, supply connections, logic interface, and analog terminal assignments. Functional differences (NC-only, NO-only, or mixed) are implemented internally and do not affect physical layout or PCB design.
