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, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.4Ω typical on-resistance match between channels, and 2.5nA max off-leakage at +85°C, enabling low-distortion audio-signal routing and reed-relay replacement in test equipment.
For engineers reviewing the MAX4603EAE datasheet, MAX4603EAE pinout, MAX4603EAE application, or MAX4603EAE equivalent, key selection criteria include its dual-supply (±4.5V to ±20V) or single-supply (+4.5V to +36V) operation, TTL/CMOS-compatible logic thresholds, and guaranteed RON flatness of 0.4Ω over ±10V signal range.
Technical Context
The MAX4603EAE implements CMOS-based transmission-gate architecture with independent control of four SPST switches-two NO and two NC-each supporting rail-to-rail analog signals up to ±20V. Its logic inputs feature fixed 0.8V/2.4V TTL/CMOS thresholds, eliminating level-shifting needs when operated from ±15V or +12V supplies.
Internal ESD protection exceeds 2000V per Method 3015.7, and the device maintains <0.5Ω RON mismatch and <0.4Ω RON flatness across –40°C to +85°C, ensuring consistent channel matching in multi-path signal switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| RON Match | 0.5Ω max - guarantees matched gain/attenuation across channels in differential or multi-path routing |
| RON Flatness | 0.4Ω max over ±10V - preserves linearity and THD performance across full signal swing |
| Off-Leakage Current | 2.5nA max at +85°C - prevents DC error accumulation in high-impedance sensor or integrator interfaces |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, test, and avionics power architectures |
| Logic Thresholds | 0.8V low / 2.4V high - enables direct interface with standard TTL/CMOS controllers without biasing |
| Turn-On/Off Time | 160ns / 170ns typical - suitable for multiplexing up to ~3MHz without significant settling delay |
Pinout & Package
MAX4603EAE is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, measuring 6.2mm × 5.3mm, optimized for space-constrained PCB layouts while maintaining thermal performance up to +85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs determining NO/NC state of corresponding switch; TTL/CMOS compatible |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection points for all switches |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - connected to COM when IN = 0; MAX4603 uses NC1, NC2, NC3, NC4 only for pins 3, 14, 11, 6 |
| - | NO1–NO4 | Normally open analog terminals - connected to COM when IN = 1; MAX4603 uses NO1, NO4 only (pins not assigned to NC) |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Digital and analog reference ground - shared return for logic and switch circuitry |
| 12 | VL | Logic supply input - accepts 2.7V to V+ and sets logic threshold reference |
| 13 | V+ | Positive analog supply rail - defines upper analog signal limit and powers internal switch core |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±15V op-amp interfacing and audio line-level routing |
| Guaranteed RON match | 0.5Ω max mismatch between any two channels - enables precise gain-matching in instrumentation multiplexers |
| Low charge injection | 20pC typical - minimizes voltage glitch on high-impedance nodes during switching, critical in sample-and-hold circuits |
| ESD protection | >2000V per Method 3015.7 - enhances robustness in automated test handlers and field-deployed equipment |
| Single/dual supply flexibility | Operates from +4.5V to +36V or ±4.5V to ±20V - eliminates need for separate supply rails in mixed-signal 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, 0.8Ω RON, ±15V supply, but requires VL = V+ and lacks NC/NO mixing; no guaranteed RON match spec | Better RON and bandwidth (170MHz), but unsuitable where mixed NO/NC topology or tight channel matching is required | Select ADG1404BRUZ only when ultra-low RON and high-frequency performance outweigh topology and matching needs. |
| TS5A23157DCUR | 2-channel, 0.9Ω RON, +1.65V to +5.5V supply only; no dual-supply support; 10nA leakage at +85°C | Optimized for portable low-voltage systems; cannot replace MAX4603EAE in ±15V or high-voltage industrial designs | Choose TS5A23157DCUR for battery-powered signal routing below 5.5V; avoid for industrial/test equipment requiring wide supply or rail-to-rail swing. |
Compared with ADG1404BRUZ and TS5A23157DCUR, the MAX4603EAE uniquely combines mixed NO/NC topology, guaranteed 0.5Ω RON match, and ±20V dual-supply capability - making it irreplaceable in reed-relay-replacement and calibrated test-system designs where channel consistency and voltage range are non-negotiable.

FAQ
What is the operating temperature range for the MAX4603EAE?
The MAX4603EAE is rated for operation from –40°C to +85°C, as confirmed by its "E" grade suffix and electrical specifications tested across this full industrial temperature range. All key parameters-including on-resistance, leakage current, and timing-are guaranteed over this interval, making the MAX4603EAE suitable for harsh-environment applications such as avionics and industrial control systems.
Does the MAX4603EAE support single-supply operation?
Yes, the MAX4603EAE supports single-supply operation from +4.5V to +36V. In this configuration, V− is connected to GND, V+ supplies the positive rail, and VL may be tied to V+ or a lower logic-compatible voltage (≥2.7V). The device maintains rail-to-rail analog signal handling and TTL/CMOS-compatible logic thresholds under single-supply conditions, as verified in the Electrical Characteristics table for V+ = 12V, V− = 0.
How many normally open and normally closed switches does the MAX4603EAE contain?
The MAX4603EAE contains exactly two normally open (NO) switches and two normally closed (NC) switches - a hybrid configuration distinct from the MAX4601 (four NC) and MAX4602 (four NO). This arrangement is explicitly defined in the General Description and confirmed in the Pin Configurations diagram, where IN1/IN4 control NO1/NO4 and IN2/IN3 control NC2/NC3.
What is the maximum off-isolation performance of the MAX4603EAE?
The MAX4603EAE provides –56dB minimum off-isolation at 1MHz, measured with 50Ω source and load impedances. This value is specified in the Dual-Supply Electrical Characteristics table and reflects signal rejection between an active and inactive channel. Off-isolation degrades above 5MHz due to capacitive coupling, so for RF applications beyond 10MHz, alternative devices like the MAX440 series are recommended.
Can the MAX4603EAE be used with ±15V supplies and 5V logic control?
Yes, the MAX4603EAE is fully compatible with ±15V analog supplies and 5V logic control. Its logic inputs have fixed 0.8V/2.4V thresholds, and VL can be set to 5V independently of V+/V−. The Electrical Characteristics table explicitly validates operation under V+ = +15V, V− = –15V, VL = 5V, confirming correct switching behavior, leakage, and RON performance in this configuration.
