Product details
Overview
MAX4606CSE+ from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, 5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling-designed for precision audio routing and automated test equipment where low distortion and channel matching are critical.
For engineers reviewing the MAX4606CSE+ datasheet, MAX4606CSE+ pinout, MAX4606CSE+ application, or MAX4606CSE+ equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases in avionics and PBX systems, and validated alternative parts with documented functional and interface differences.
Technical Context
The MAX4606CSE+ implements CMOS-based SPST switching with independent digital control per channel (IN1–IN4), supporting mixed NC/NO topology in a single 16-pin SO package. Its on-resistance flatness (≤0.5Ω over ±10V signal range) and matched RON (≤0.5Ω between channels) ensure minimal gain error and crosstalk in multiplexed signal paths.
Logic inputs accept TTL/CMOS thresholds (0.8V/2.4V) across full supply ranges, enabling direct interfacing with microcontrollers or FPGAs without level-shifting. Internal ESD protection (>2000V per Method 3015.7) and guaranteed off-leakage ≤2.5nA at +85°C support robust operation in industrial and avionics environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures <1% gain error in 500Ω impedance circuits and low insertion loss in audio paths. |
| 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 attenuation across full analog input range, critical for linearity-sensitive applications. |
| Off-Leakage Current | 2.5nA max at +85°C - prevents DC offset drift in high-impedance sensor front-ends or precision measurement nodes. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports legacy ±15V test gear and modern 12V/24V industrial systems without external regulators. |
| Turn-On/Off Time | 120ns/130ns typical - enables reliable switching of audio-band signals (<20kHz) and fast data acquisition sequencing. |
| ESD Protection | >2000V HBM - eliminates need for external TVS diodes in board-level ESD-prone environments like field-deployed test equipment. |
Pinout & Package
MAX4606CSE+ uses a 16-pin narrow SOIC (SOIC-N) package, 7.5mm × 10.3mm body, 1.27mm pitch, with exposed pad not electrically connected. Pin 1 marked by notch or dot; pins numbered counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs: logic high enables NO path / disables NC path; logic low disables NO path / enables NC path. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path shared between NC and NO contacts per channel. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = low; MAX4606 uses NC1, NC2, NC3, NC4 only on pins 3, 6, 11, 14. |
| 4 | V− | Negative analog supply rail - connect to GND for single-supply operation; must be ≤ V+ − 0.3V. |
| 5 | GND | Digital ground reference - separate from analog supplies but tied to system ground plane for noise control. |
| 12 | VL | Logic supply input - accepts 2.7V to 5.5V; decoupling capacitor required for stable switching edge integrity. |
| 13 | V+ | Positive analog supply rail - sets upper signal swing limit; must be ≥ V− + 0.3V and ≤ +44V relative to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from V− to V+, enabling full utilization of ±15V or +12V supply rails without clipping. |
| Guaranteed RON match (≤0.5Ω) | Ensures ≤0.1% gain mismatch between channels in multi-channel instrumentation amplifiers or ADC front-ends. |
| TTL/CMOS-compatible logic inputs | Eliminates level-shifter ICs when interfacing with 3.3V/5V microcontrollers or CPLDs in mixed-voltage systems. |
| Low charge injection (225pC typical) | Minimizes voltage glitch on high-impedance nodes (e.g., sample-hold capacitors), preserving ADC accuracy. |
| High off-isolation (−62dB typical) | Reduces crosstalk between active and inactive signal paths in dense multiplexer designs (e.g., 16×1 audio matrix). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Quad SPST, 1.8Ω RON, ±15V supply, no NC/NO mixing - all channels NO-only. | Requires external pull-downs to emulate NC behavior; better for ultra-low-RON needs but lacks native NC/NO flexibility. | Select ADG1412BRUZ when lowest on-resistance is mandatory and NC functionality can be synthesized externally. |
| TS5A3157DCUR | Single-pole double-throw (SPDT), 0.75Ω RON, +1.65V to +5.5V supply only - no dual-supply support. | Not suitable for ±15V or +24V systems; limited to low-voltage portable/audio applications. | Choose TS5A3157DCUR for battery-powered devices needing SPDT topology and sub-1Ω RON, but not for industrial or avionics rails. |
Compared with MAX4606CSE+, ADG1412BRUZ offers lower RON but requires redesign to replicate NC/NO duality, while TS5A3157DCUR supports only low-voltage single-supply operation-neither provides the integrated mixed-mode switching and wide supply range of the MAX4606CSE+.

FAQ
What is the operating temperature range for the MAX4606CSE+?
The MAX4606CSE+ is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range aligns with its C-suffix designation (e.g., MAX4606CSE+), making it suitable for indoor industrial equipment and telecom infrastructure where ambient thermal management is controlled. The MAX4606ESE+ variant extends to −40°C to +85°C for extended-environment deployment.
Does the MAX4606CSE+ support both single-supply and dual-supply configurations?
Yes, the MAX4606CSE+ supports both configurations: single supply from +4.5V to +36V (with V− tied to GND) and dual supply from ±4.5V to ±20V. This flexibility allows direct integration into legacy ±15V test gear and modern +12V/+24V industrial systems without external level-shifting or supply splitting circuitry-verified in the Electrical Characteristics tables for both modes.
How many normally closed and normally open switches does the MAX4606CSE+ contain?
The MAX4606CSE+ contains exactly two normally closed (NC) switches and two normally open (NO) switches - a unique mixed topology among the MAX460x series. This is confirmed in the General Description ("MAX4606 has two NC and two NO switches") and reflected in the MAX4606-specific pin diagram showing NC1/NC2 on pins 3/6 and NO3/NO4 on pins 11/14.
What is the maximum off-leakage current specification for the MAX4606CSE+ at elevated temperature?
The MAX4606CSE+ guarantees off-leakage current ≤2.5nA maximum at +85°C, as stated in the General Description and confirmed in the Electrical Characteristics table under "INO_, INC_ Off-Leakage Current (NO_ or NC_)" for TA = TMIN to TMAX. This value applies to both NC and NO terminals when unselected, ensuring minimal signal corruption in high-impedance measurement paths.
Is the MAX4606CSE+ pin-compatible with other variants in the MAX460x family?
Yes, the MAX4606CSE+ shares identical pinout and package (16-pin narrow SOIC) with MAX4604CSE+ and MAX4605CSE+, as shown in the Pin Configurations section. All three variants use the same physical layout and terminal assignments - only internal switch configuration (NC-only, NO-only, or mixed) differs, allowing drop-in replacement in PCBs designed for any MAX460x SOIC variant.
