Product details
Overview
MAX4661CAE+ from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.5Ω max RON match between channels, and 5nA max off-leakage at +85°C, enabling low-distortion switching in data acquisition and test equipment.
For engineers reviewing the MAX4661CAE+ datasheet, MAX4661CAE+ pinout, MAX4661CAE+ application, or MAX4661CAE+ equivalent, this page provides verified electrical specs, package mapping to 16-pin SSOP, real-world use cases in ADC front-ends and audio routing, and two validated alternative parts with documented functional differences.
Technical Context
The MAX4661CAE+ implements CMOS-based transmission-gate architecture with independent logic-level control inputs (IN1–IN4) and separate analog supply rails (V+, V−) plus dedicated logic supply (VL). Its NC topology ensures default-closed signal paths when control inputs are logic low, supporting fail-safe analog routing.
It supports dual-supply operation (±4.5V to ±20V) or single-supply operation (+4.5V to +36V), with TTL/CMOS-compatible input thresholds (0.8V/2.4V) guaranteed across full temperature range (0°C to +70°C). Internal ESD protection exceeds 2kV per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in ≤10mA analog paths |
| RON Match | 0.5Ω max - enables precise channel-to-channel gain matching in multi-path signal conditioning |
| RON Flatness | 0.5Ω max over ±10V signal range - maintains consistent insertion loss across full analog swing |
| Off-Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and sample-and-hold circuits |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and wide-dynamic-range instrumentation |
| Logic Compatibility | TTL/CMOS inputs with 0.8V/2.4V thresholds - eliminates level-shifting in mixed-voltage controller designs |
| ESD Protection | >2kV HBM - reduces need for external protection in automated test equipment PCB layouts |
Pinout & Package
MAX4661CAE+ is housed in a 16-pin shrink small-outline package (SSOP), 5.3mm × 6.2mm body, 0.65mm lead pitch, JEDEC MO-153 compliant. Thermal resistance θJA = 140°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; logic low closes corresponding NC switch |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load return path |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = low |
| 4 | V− | Negative analog supply rail; tie to GND for single-supply operation |
| 5 | GND | Logic and substrate ground reference |
| 12 | VL | Dedicated logic supply input - decouples digital noise from analog supplies |
| 13 | V+ | Positive analog supply rail - sets upper limit of rail-to-rail signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for ±15V op-amp interfaces and unipolar 0–36V sensor outputs |
| Guaranteed RON Match | 0.5Ω max mismatch between any two switches - enables matched gain/phase in differential or multi-channel sampling |
| Low Charge Injection | 20pC typical - minimizes voltage glitch in sample-and-hold and multiplexed ADC applications |
| Break-Before-Make Exclusion | Not implemented - MAX4661CAE+ is NC-only; avoids unintended signal interruption during switching transitions |
| High Off-Isolation | −56dB at 1MHz - suppresses crosstalk between inactive channels in dense analog routing |
Applications
| Reed Relay Replacement | ADC Front-End Multiplexing |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4662CAE+ | Four normally open (NO) configuration instead of NC; identical RON, leakage, and supply specs | Suitable where default-open safety state is required (e.g., power-off isolation) | Select MAX4662CAE+ only if system requires open-circuit default behavior on power loss or reset |
| ADG1414BRUZ | 2.7Ω max RON, ±15V dual-supply only, no VL pin, −40°C to +125°C rating | Better high-temp suitability but lacks single-supply flexibility and logic supply decoupling | Prefer ADG1414BRUZ for automotive under-hood or extended-temperature industrial control where VL isolation is not needed |
Compared with MAX4661CAE+, MAX4662CAE+ offers inverted logic behavior (NO vs NC) with identical analog performance, while ADG1414BRUZ trades single-supply operation and VL decoupling for wider temperature range and higher voltage tolerance - requiring layout and supply redesign.

FAQ
What is the operating temperature range for MAX4661CAE+?
The MAX4661CAE+ is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range is confirmed in the Ordering Information table and applies specifically to the 'C' grade suffix. The device uses silicon process and packaging validated for stability within this range, with all electrical specifications guaranteed across the full span.
Does MAX4661CAE+ support single-supply operation?
Yes, MAX4661CAE+ supports single-supply operation from +4.5V to +36V. In this mode, V− must be connected to GND, V+ supplies the positive rail, and VL accepts a separate +2.7V to +6V logic supply. All key parameters-including RON, leakage, and switching times-are specified and tested under single-supply conditions per the Electrical Characteristics table.
How is the normally closed (NC) functionality implemented in MAX4661CAE+?
MAX4661CAE+ implements NC behavior via internal CMOS transmission gates configured so that each switch conducts between COM and NC pins when its respective IN pin is logic low (≤0.8V). When IN rises to logic high (≥2.4V), the channel opens. This is confirmed in the Pin Configurations diagram and Truth Table on page 1 of the datasheet.
What is the maximum continuous current rating per switch in MAX4661CAE+?
The MAX4661CAE+ supports ±200mA continuous current through any COM, NC, or NO terminal, as stated in the Absolute Maximum Ratings table. This rating holds across the full operating temperature range and is independent of supply voltage. Exceeding this value risks thermal damage or parametric shift.
Is MAX4661CAE+ pin-compatible with MAX4662CAE+ or MAX4663CAE+?
Yes, MAX4661CAE+, MAX4662CAE+, and MAX4663CAE+ share identical 16-pin SSOP footprints and pinouts. However, their internal switch configurations differ: MAX4661CAE+ is NC-only, MAX4662CAE+ is NO-only, and MAX4663CAE+ combines two NC and two NO switches with break-before-make. Swapping requires logic inversion or signal reassignment.
