Product details
Overview
MAX4603CAE+T from Maxim Integrated is a quad SPST analog switch IC with two normally closed (NC) and two normally open (NO) channels, 4Ω max on-resistance at +25°C, ±15V dual-supply or +12V single-supply operation, and rail-to-rail signal handling up to ±10V - used in audio-signal routing and PBX system switching where low distortion and channel matching are critical.
For engineers reviewing the MAX4603CAE+T datasheet, MAX4603CAE+T pinout, MAX4603CAE+T application, or MAX4603CAE+T equivalent, key selection criteria include guaranteed RON match (≤0.4Ω), off-leakage <0.5nA at +85°C, TTL/CMOS-compatible logic thresholds, and SSOP-16 package compatibility with automated SMT assembly.
Technical Context
The MAX4603CAE+T implements four independent CMOS transmission gates in a single die, each with separate NC/NO configuration per channel pair. Its control architecture uses buffered digital inputs with fixed 0.8V/2.4V logic thresholds, enabling direct interface with +5V logic without level-shifting when VL = +5V and V± supplies are ±15V.
It supports bidirectional analog signal routing across full supply rails (V− to V+), with on-resistance flatness ≤0.4Ω over −10V to +10V signal range and guaranteed channel-to-channel RON matching for precision multiplexing in test equipment and avionics signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +25°C, ensuring minimal voltage drop and power loss in signal paths carrying up to ±10V analog signals |
| RON Match | ≤0.4Ω max between channels, enabling accurate gain-matched signal routing in instrumentation front-ends |
| Supply Range | +4.5V to +36V single supply or ±4.5V to ±20V dual supply - supports industrial +24V and legacy ±15V systems |
| Off-Leakage Current | ≤0.5nA at +85°C, minimizing DC error in high-impedance sensor interfaces and sample-hold circuits |
| Logic Thresholds | 0.8V low / 2.4V high, providing robust TTL/CMOS compatibility without external biasing on +5V control lines |
| Turn-On/Off Time | 160ns / 170ns typical at VCOM = 10V, enabling reliable switching in audio-band and medium-speed data acquisition |
| Charge Injection | 20pC typical, limiting voltage glitch amplitude in precision sampling applications with >1MΩ source impedance |
Pinout & Package
MAX4603CAE+T is housed in a 16-pin shrink small-outline package (SSOP) with 0.65mm lead pitch, JEDEC MO-137AC compliant, suitable for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic selects NO path (IN=2.4V) or NC path (IN=0.8V) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; bidirectional signal ports connected to either NO or NC based on IN state |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals; COM connected to NC when IN = 0.8V (MAX4603 has NC on CH1/CH4) |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation (+4.5V to +36V) |
| 5 | GND | Digital ground reference for logic inputs and VL supply return |
| 12 | VL | Logic supply input; accepts +2.7V to +7V, decoupled separately to minimize digital noise coupling into analog paths |
| 13 | V+ | Positive analog supply rail; supports up to +36V or ±20V, defining maximum signal swing (V− to V+) |
| 14, 11 | NO2, NO3 | Normally open analog terminals; COM connected to NO only when IN = 2.4V (MAX4603 has NO on CH2/CH3) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+, enabling full utilization of ±15V or +12V supply rails without clipping |
| Guaranteed RON flatness | ≤0.4Ω variation over −10V to +10V signal range, preserving linearity in audio and instrumentation amplifiers |
| TTL/CMOS-compatible inputs | Fixed 0.8V/2.4V thresholds eliminate need for external level shifters when interfacing with standard logic families |
| ESD protection | ≥2000V per Method 3015.7, reducing susceptibility to handling damage during board assembly and field service |
| Low charge injection | 20pC typical, minimizing transient errors in sample-and-hold and switched-capacitor filter designs |

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, 1.8Ω RON, ±15V supply, but NO-only topology (no NC paths) | Suitable for unidirectional signal routing only; cannot replicate MAX4603CAE+T's mixed NC/NO channel pairing | Select when lower on-resistance is prioritized and NC functionality is unnecessary |
| TS5A3157DCUR | Single-channel, 0.75Ω RON, +1.65V to +5.5V supply, SC70-6 package | Limited to low-voltage, single-switch applications; lacks quad integration and high-voltage capability | Choose for space-constrained, battery-powered designs requiring ultra-low RON below +5.5V |
Compared with ADG1412BRUZ and TS5A3157DCUR, the MAX4603CAE+T uniquely delivers mixed NC/NO topology in a quad configuration with ±20V dual-supply support - essential for relay-replacement and fault-tolerant signal routing where channel diversity and high-voltage operation are mandatory.

FAQ
What is the operating temperature range for MAX4603CAE+T?
The MAX4603CAE+T is specified for commercial temperature operation from 0°C to +70°C. This range is confirmed in the Ordering Information table and Electrical Characteristics sections of the datasheet, where parameters like RON, leakage, and timing are guaranteed across this interval. The 'C' suffix in MAX4603CAE+T explicitly denotes the 0°C to +70°C grade.
Does MAX4603CAE+T support single-supply operation?
Yes, MAX4603CAE+T supports single-supply operation from +4.5V to +36V. In this mode, V− is connected to GND, V+ supplies the positive rail, and analog signals swing from GND to V+. The datasheet confirms rail-to-rail performance and specifies electrical characteristics under +12V single-supply conditions, including RON = 3Ω typical and off-isolation >55dB.
How are the NC and NO channels distributed in MAX4603CAE+T?
In MAX4603CAE+T, channels 1 and 4 are normally closed (NC), while channels 2 and 3 are normally open (NO). This is explicitly shown in the "SWITCHES" diagram on page 1 of the datasheet and confirmed in the Pin Description table, where pins 3/14/11/6 are labeled NC1/NC2/NC3/NC4 for MAX4601, but for MAX4603 only NC1, NC4, NO2, and NO3 are functional - matching the truth table showing IN1/IN4 controlling NC paths and IN2/IN3 controlling NO paths.
What is the maximum analog signal voltage supported by MAX4603CAE+T?
MAX4603CAE+T supports analog signals from V− to V+, with absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. Under recommended operating conditions, it handles rail-to-rail signals up to ±10V with guaranteed RON flatness and leakage performance - verified in Electrical Characteristics tables for both dual-supply (±15V) and single-supply (+12V) configurations.
Is MAX4603CAE+T pin-compatible with other MAX460x variants?
Yes, MAX4603CAE+T shares identical pinout and package (16-pin SSOP) with MAX4601CAE and MAX4602CAE. The Pin Configurations diagram on page 1 shows identical top-view layouts across all three parts, and the Pin Description table lists consistent pin functions (e.g., IN1–IN4, COM1–COM4, V+, V−, GND, VL) regardless of NC/NO configuration - enabling drop-in replacement where channel logic matches the application.
