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 signal handling from V+ to GND. It operates from a single +2V to +12V supply and supports TTL/CMOS logic compatibility in 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 considerations include its dual NO/NC topology, guaranteed on-resistance flatness (18Ω max), sub-2nA off-leakage at +85°C, 300MHz on-channel bandwidth, and compatibility with +5V single-supply industrial signal-switching designs.
Technical Context
The MAX4612CPD implements four independent CMOS transmission gates controlled by digital inputs IN1–IN4, with dedicated NO1/NO2 and NC3/NC4 terminals per its dual-configuration architecture. Its on-resistance remains flat (≤18Ω) across the full analog signal range (0V to V+), and channel matching (ΔRON ≤ 4Ω) ensures consistent gain and timing in multi-path signal routing.
All switches support bidirectional rail-to-rail analog signals and exhibit <2nA off-leakage at +85°C, enabling precision sample-and-hold and low-drift sensor multiplexing. Logic thresholds (+0.8V low, +2.4V high at +5V supply) guarantee robust noise immunity without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery or adapter-powered systems without regulation. |
| On-Resistance (RON) | 100Ω max at +5V - limits voltage drop and power loss in low-current analog paths (e.g., sensor front-ends). |
| On-Resistance Match (ΔRON) | 4Ω max - ensures ≤0.5% gain error between channels in differential or switched-gain amplifier configurations. |
| Off-Leakage Current | 2nA max at +85°C - preserves charge integrity in sample-and-hold circuits for ≥100ms hold times. |
| Bandwidth (ON) | 300MHz - supports switching of audio, video, and medium-speed digital control signals without attenuation. |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V at +5V) - allows direct interface with microcontrollers and FPGAs without level translators. |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field service without external protection. |
Pinout & Package
MAX4612CPD is supplied in a 14-pin plastic DIP package (0°C to +70°C operating range), with through-hole mounting and standard 0.3-inch width. 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 |
|---|---|---|
| Pin 1, Pin 8 | NO1, NO3 | Normally open analog output terminals - connect only when corresponding IN1/IN3 is HIGH; used for default-open signal gating. |
| Pin 3, Pin 11 | NC2, NC4 | Normally closed analog output terminals - disconnect only when corresponding IN2/IN4 is HIGH; used for default-closed fail-safe paths. |
| Pin 2, Pin 4, Pin 9, Pin 10 | COM1–COM4 | Common analog input nodes - shared signal entry point for each SPST switch; must be routed with controlled impedance for RF-sensitive applications. |
| Pin 13, Pin 5, Pin 6, Pin 12 | IN1–IN4 | Digital control inputs - accept 0.8V/2.4V logic thresholds; no pull-up/down required; drive directly from GPIOs. |
| Pin 7 | GND | Digital/analog reference ground - must be connected to system ground plane with low-inductance path to minimize switching noise coupling. |
| Pin 14 | V+ | Single positive supply - powers both analog switch core and logic interface; requires local 0.1µF ceramic bypass to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NO/NC configuration | Two independent NO and two NC switches enable simultaneous active-high and active-low signal routing in safety-critical or redundancy-driven designs. |
| Rail-to-rail analog signal handling | Supports input/output signals from GND to V+ - eliminates clipping in unipolar sensor interfaces and DC-coupled audio paths. |
| Guaranteed on-resistance flatness | ≤18Ω variation over full signal range - maintains linearity in precision instrumentation amplifiers and programmable gain stages. |
| Low temperature drift leakage | <2nA off-leakage at +85°C - ensures stable biasing in thermally demanding environments like automotive cabin modules. |
| High off-isolation | −60dB at 1MHz - suppresses crosstalk between adjacent channels in multi-signal routing boards. |
| Fast switching | 65ns max turn-on, 28ns max turn-off - supports >10MHz multiplexing rates in data acquisition front-ends. |

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 timing specs. | Suitable where all paths require default-closed behavior (e.g., fail-safe power monitoring). | Select MAX4611CPD when continuous conduction is required unless actively interrupted. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON at +5V, but only NO configuration; ±15V dual-supply capable. | Better for high-precision, low-RON applications requiring wider voltage swing, not single-supply portability. | Choose ADG1412BRUZ only if sub-2Ω on-resistance and dual-supply operation outweigh footprint and cost penalties. |
Compared with MAX4611CPD (all-NC) and ADG1412BRUZ (low-RON NO-only), the MAX4612CPD uniquely balances mixed NO/NC functionality, 100Ω RON, and +2V–+12V single-supply flexibility-making it optimal for compact, battery-operated systems needing configurable signal routing without redesigning PCB layout.

FAQ
What is the maximum supply voltage for MAX4612CPD?
The absolute maximum supply voltage (V+) for MAX4612CPD is +13V referenced to GND. Operation above +12V is possible but requires strict adherence to the +13V limit and local 0.1µF bypass capacitance at Pin 14. Exceeding this rating risks permanent damage, especially under thermal stress or voltage transients.
Does MAX4612CPD support rail-to-rail analog signals?
Yes, MAX4612CPD supports rail-to-rail analog signals from GND to V+. Each switch handles voltages across the full supply range without distortion or clipping, enabling direct connection to unbuffered sensors, DAC outputs, or ADC inputs in single-supply systems.
How many NO and NC switches does MAX4612CPD contain?
MAX4612CPD contains exactly two normally open (NO) switches (NO1, NO2) and two normally closed (NC) switches (NC3, NC4), as confirmed by its truth table and pin configuration diagrams in the official datasheet. This dual-configuration enables flexible fail-safe and active-gate signal routing.
What is the on-resistance match specification for MAX4612CPD?
MAX4612CPD guarantees a maximum on-resistance match (ΔRON) of 4Ω between any two channels at +25°C and +5V supply. This specification ensures predictable gain consistency in multi-channel instrumentation, such as programmable gain amplifiers or differential signal selectors.
Is MAX4612CPD compatible with TTL and CMOS logic levels?
Yes, MAX4612CPD features guaranteed logic thresholds of +0.8V (low) and +2.4V (high) when operated from a +5V supply, ensuring full compatibility with standard TTL and CMOS outputs without level-shifting circuitry or pull-up resistors.
