Product details
Overview
MAX4603EAE+T 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, PBX systems, and automatic test equipment where low distortion and mechanical relay replacement are critical.
For engineers reviewing the MAX4603EAE+T datasheet, MAX4603EAE+T pinout, MAX4603EAE+T application, or MAX4603EAE+T equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases, and validated alternative options for analog switching design-in and BOM optimization.
Technical Context
The MAX4603EAE+T implements four independent CMOS-based SPST switches in a single 16-pin SSOP package, with dedicated IN/COM/NO/NC terminals per channel and separate VL logic supply input. Its architecture guarantees matched on-resistance (≤0.5Ω) and flat on-resistance (≤0.5Ω) across the full ±10V analog signal range.
It supports TTL/CMOS-compatible digital control inputs (0.8V/2.4V thresholds), operates over –40°C to +85°C, and features <0.5nA off-leakage at +85°C, 2000V ESD protection, and <20pC charge injection - enabling precision signal routing without distortion or settling error in sensitive analog paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss when routing ±10V analog signals at 10mA. |
| RON Match | 0.5Ω max - enables precise channel-to-channel signal balancing in differential or multi-path routing. |
| RON Flatness | 0.5Ω max over ±10V - maintains consistent gain and linearity across full analog input swing. |
| Off-Leakage Current | 2.5nA max at +85°C - prevents DC error accumulation in high-impedance sensor or filter nodes. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, telecom, and avionics rails without level-shifting. |
| Logic Thresholds | 0.8V low / 2.4V high - ensures reliable switching with standard 5V TTL or CMOS controllers. |
| Turn-On/Off Time | 160ns / 170ns typical - suitable for multiplexing audio and medium-speed data acquisition (<5MHz). |
Pinout & Package
MAX4603EAE+T is housed in a 16-pin shrink small-outline package (SSOP), 5.3mm × 6.2mm body, 0.65mm lead pitch, moisture sensitivity level 1 (MSL1), RoHS-compliant.
| 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; connect to signal source or load node shared by NO/NC paths. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals; conduct to COM when IN = 0V (MAX4603 uses NC on channels 1 & 4). |
| 4, 13 | V− / V+ | Analog supply rails; support ±15V dual or +12V single operation; must be powered before logic inputs. |
| 5 | GND | Ground reference for analog and logic sections; requires low-impedance connection to minimize noise coupling. |
| 12 | VL | Logic supply input; accepts 2.7V to 5.5V to set input threshold levels independently of analog rails. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous ±10V differential signals without clipping or distortion - essential for audio and instrumentation front-ends. |
| Guaranteed RON match ≤0.5Ω | Enables accurate channel pairing in differential switching, calibration paths, or multi-channel data acquisition systems. |
| Low 20pC charge injection | Minimizes voltage glitches at COM during switching - critical for sample-and-hold circuits and precision ADC drivers. |
| TTL/CMOS-compatible logic inputs | Eliminates need for external level shifters when interfacing with microcontrollers, FPGAs, or logic families operating at 3.3V or 5V. |
| ESD protection >2000V HBM | Reduces risk of field failure during handling or system integration without requiring additional transient suppression. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRUZ | Single-supply only (+3V to +16.5V); 4.5Ω RON; no NC/NO mix - all four channels are NO. | Better suited for low-voltage portable systems; lacks dual-supply flexibility and mixed switch topology. | Select when cost and supply simplicity outweigh need for NC functionality and wide voltage range. |
| TS5A3157DCKR | Single-channel SPDT; 0.75Ω RON; +1.65V to +5.5V supply; no dual-rail support. | Requires four devices to match quad function; optimized for USB/audio switching, not industrial signal routing. | Choose only for space-constrained, low-voltage consumer designs - not a functional or pinout substitute. |
Compared with ADG465BRUZ and TS5A3157DCKR, the MAX4603EAE+T uniquely combines dual-supply operation, mixed NO/NC topology, sub-3Ω RON, and guaranteed matching - making it the only option among the three qualified for ±15V telecom and ATE applications requiring channel symmetry and rail-to-rail fidelity.

FAQ
What is the operating temperature range for MAX4603EAE+T?
The MAX4603EAE+T is rated for operation from –40°C to +85°C. This extended industrial temperature range ensures reliable performance in telecom infrastructure, automated test equipment, and avionics signal conditioning where ambient conditions vary widely. The device's leakage current, on-resistance, and switching times are fully specified across this range.
Does MAX4603EAE+T support dual-supply operation?
Yes, MAX4603EAE+T supports dual-supply operation from ±4.5V to ±20V, including standard ±15V rails. It also operates from a single supply of +4.5V to +36V. The dual-supply mode enables true bipolar signal switching (e.g., ±10V), while the single-supply mode simplifies power design in industrial control and audio applications.
How many normally open and normally closed switches does MAX4603EAE+T contain?
The MAX4603EAE+T contains exactly two normally open (NO) switches and two normally closed (NC) switches - a unique mixed configuration within the MAX460x family. Channels 1 and 4 are NC; channels 2 and 3 are NO. This allows simultaneous break-before-make and make-before-break behavior in complex signal path control schemes.
What is the maximum off-leakage current of MAX4603EAE+T at +85°C?
The maximum off-leakage current for MAX4603EAE+T is 2.5nA at TA = +85°C, measured at NO or NC terminals. This ultra-low leakage preserves DC accuracy in high-impedance sensor interfaces and sample-and-hold circuits, and is guaranteed by 100% testing at hot temperature per the datasheet.
Is MAX4603EAE+T pin-compatible with other devices in the MAX460x family?
Yes, MAX4603EAE+T shares identical pinout and package (16-pin SSOP) with MAX4601EAE+T and MAX4602EAE+T. All three devices have the same terminal assignments for V+, V−, GND, VL, INx, COMx, NOx, and NCx - enabling direct substitution in PCB layouts when switching logic (NO vs NC) is adjusted in firmware or external logic.
