Product details
Overview
MAX4612CPD+ from Maxim Integrated is a quad, low-voltage, SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, 100Ω max on-resistance at +5V, 4Ω max channel-to-channel on-resistance match, and rail-to-rail analog signal handling from V+ to GND. It operates from a single +2V to +12V supply and supports battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4612CPD+ datasheet, MAX4612CPD+ pinout, MAX4612CPD+ application, or MAX4612CPD+ equivalent, key selection criteria include guaranteed on-resistance flatness (18Ω max), <2nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and 14-pin PDIP package suitability for prototyping and industrial control I/O conditioning.
Technical Context
The MAX4612CPD+ implements four independent CMOS transmission gates controlled by digital inputs IN1–IN4, each driving one NO or NC switch pair. Its architecture ensures matched RON across channels and flat on-resistance over the full 0V to V+ analog range-critical for precision multiplexing in sample-and-hold circuits.
All switches support bidirectional analog signals, handle ±0.3V beyond rails via internal clamping diodes, and exhibit 300MHz on-channel bandwidth with –60dB off-isolation at 1MHz. Logic thresholds (0.8V/2.4V) are fixed-not supply-scaled-enabling reliable operation across +3V to +12V supplies without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 100Ω max at +5V supply - ensures minimal signal attenuation in low-level sensor interfaces |
| On-Resistance Match | 4Ω max between channels - enables accurate differential signal switching without gain error |
| Analog Signal Range | 0V to V+ - supports rail-to-rail input/output in single-supply systems like portable instrumentation |
| Off-Leakage Current | 2nA max at +85°C - preserves integrity of high-impedance nodes in battery-operated data loggers |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) - eliminates need for external level shifters when driven by microcontrollers |
| Supply Range | +2V to +12V single supply - allows direct integration with Li-ion, 3.3V, and 5V system rails |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive test equipment and field-deployed modules |
Pinout & Package
MAX4612CPD+ uses a 14-pin plastic DIP (PDIP) package with 0.3-inch width, through-hole mounting, and RoHS-compliant lead-free finish. Pin 7 is GND; Pin 14 is V+; Pins 1,8 are NO1/NO3; Pins 3,11 are NC2/NC4; Pins 2,4,9,10 are COM1–COM4; Pins 13,5,6,12 are IN1–IN4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog terminals - connect only when corresponding IN1/IN3 is HIGH; used for default-open signal paths |
| 3, 11 | NC2, NC4 | Normally closed analog terminals - disconnect only when corresponding IN2/IN4 is HIGH; used for default-closed safety or bias paths |
| 2, 4, 9, 10 | COM1–COM4 | Common analog ports - serve as shared signal junctions for all four switch channels |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - accept standard TTL/CMOS logic levels to toggle respective switches |
| 7 | GND | Digital ground reference - must be connected to system ground plane for stable logic and leakage control |
| 14 | V+ | Positive supply - powers both analog and digital sections; bypassing with 0.1µF capacitor near pin is mandatory for +12V operation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from 0V to V+ without clipping - essential for full-scale ADC front-end switching |
| Guaranteed on-resistance flatness | 18Ω max variation across signal range - maintains consistent gain in programmable-gain amplifier paths |
| Low charge injection | 1pC to 5pC - minimizes voltage glitch in sample-and-hold and switched-capacitor circuits |
| High off-isolation | –60dB at 1MHz - prevents crosstalk between audio channels or sensor inputs |
| Automotive-grade variants available | –40°C to +125°C operation confirmed for MAX4612ASD+/AUD+ - validates use in engine control and ADAS signal routing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611CPD+ | Four NC-only switches; identical RON, leakage, and package - no NO functionality | Suitable only where default-closed behavior is required (e.g., power fail-safe shutdown) | Select MAX4611CPD+ when all four paths must remain closed until actively opened by control logic. |
| ADG1412BRZ | Quad SPST, 1.5Ω typical RON at +5V, but requires dual ±15V or single +36V supply - not low-voltage optimized | Better performance in high-precision test equipment, but incompatible with +2V to +5V battery rails | Choose ADG1412BRZ only if sub-2Ω RON and higher voltage tolerance outweigh supply complexity and cost. |
Compared with MAX4611CPD+, the MAX4612CPD+ adds two NO switches at no penalty to leakage or matching-making it uniquely suited for mixed-path designs. Against ADG1412BRZ, it trades lower on-resistance for true low-voltage operation and simpler power architecture.

FAQ
What is the maximum supply voltage rating for MAX4612CPD+?
The absolute maximum V+ rating for MAX4612CPD+ is +13V referenced to GND. Operation above +12V is possible but requires strict adherence to layout guidelines-including a 0.1µF ceramic bypass capacitor placed directly at Pin 14 (V+) to ground. Exceeding +13V risks permanent damage, and even ±5% 12V supplies may generate transient overshoot that violates this limit.
Does MAX4612CPD+ support bidirectional analog signal flow?
Yes, MAX4612CPD+ supports fully bidirectional analog signal flow across all NO and NC channels. Each switch functions as a symmetric transmission gate: COM1 can serve as input while NO1 acts as output, or vice versa, with identical on-resistance and leakage characteristics in either direction-enabling flexible routing in both sensor excitation and measurement paths.
How does the logic threshold behavior of MAX4612CPD+ differ from supply-scaled CMOS inputs?
MAX4612CPD+ uses fixed TTL/CMOS-compatible thresholds (0.8V for logic LOW, 2.4V for logic HIGH) independent of V+. This means it reliably accepts standard 3.3V or 5V microcontroller outputs across its entire +2V to +12V supply range-unlike supply-scaled inputs that would shift thresholds and risk misinterpretation at low V+.
Can MAX4612CPD+ be used in automotive applications?
The MAX4612CPD+ itself is rated for 0°C to +70°C and is not qualified for automotive use. However, the same die is offered in automotive-grade versions: MAX4612EPD+ (–40°C to +85°C) and MAX4612ASD+ (–40°C to +125°C). These share identical electrical specs and pinout-only temperature screening and qualification differ-so PCB design can be reused across commercial and automotive variants.
What is the significance of "flat on-resistance" in MAX4612CPD+ specifications?
"Flat on-resistance" (18Ω max) means the variation in RON across the full 0V to V+ analog signal range is tightly bounded. This ensures consistent signal attenuation regardless of input voltage-critical in applications like programmable gain stages or precision voltage dividers where gain error must remain stable across the entire dynamic range.
