Product details
Overview
MAX4612ESD 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 targets precision signal routing in battery-powered instrumentation.
For engineers reviewing the MAX4612ESD datasheet, MAX4612ESD pinout, MAX4612ESD application, or MAX4612ESD 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 narrow SO package suitability for space-constrained industrial sensor interfaces.
Technical Context
The MAX4612ESD implements four independent CMOS transmission gates controlled by separate digital inputs, each configured as either NO or NC per device variant-specifically two NO (pins 1, 8) and two NC (pins 3, 11) in this part. Its on-resistance remains flat (≤18Ω variation) across the full 0V to V+ analog signal range, enabling low-distortion switching in audio and data-acquisition paths.
All switches support bidirectional analog signals from GND to V+, with leakage currents tightly specified: ≤2nA off-leakage at TA = +85°C and ≤0.2nA on-leakage at TA = +25°C. Input logic thresholds are fixed at +0.8V (low) and +2.4V (high) under +5V supply, ensuring robust interfacing with standard microcontroller GPIOs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 100Ω at +5V supply - ensures minimal voltage drop and signal attenuation in low-level sensor or audio paths |
| On-Resistance Match (max) | 4Ω between channels - enables matched gain/attenuation in multi-channel instrumentation front-ends |
| On-Resistance Flatness (max) | 18Ω over 0V to V+ range - maintains consistent insertion loss across full input signal swing |
| Off-Leakage Current (max) | 2nA at +85°C - preserves accuracy in high-impedance sample-and-hold or battery-monitoring circuits |
| Supply Voltage Range | +2V to +12V single supply - supports operation from Li-ion batteries (3.0–4.2V) up to industrial 12V rails |
| Logic Compatibility | TTL/CMOS at +5V - directly interfaces with 5V microcontrollers, FPGAs, and logic families without external buffers |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field service |
Pinout & Package
MAX4612ESD is supplied in a 14-pin narrow SO (small outline) package with exposed pad not present - distinct from QFN variants. Pin numbering follows standard SOIC layout with GND at pin 7 and V+ at pin 14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog terminals - conduct only when corresponding INx is HIGH; used for enable-controlled signal paths |
| 3, 11 | NC2, NC4 | Normally closed analog terminals - conduct when corresponding INx is LOW; provide default signal continuity |
| 2, 4, 9, 10 | COM1–COM4 | Common analog nodes - connect to signal sources or destinations; bidirectional and rail-to-rail capable |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - accept 0.8V/2.4V logic thresholds; drive internal gate bias for respective switches |
| 7 | GND | Digital/analog reference ground - must be low-impedance connection to minimize noise coupling into analog paths |
| 14 | V+ | Positive supply for analog and digital circuitry - bypass with ≥0.1µF ceramic capacitor near pin for stable switching performance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ continuous signal range - eliminates clipping in DC-coupled sensor interfaces and audio routing |
| Guaranteed on-resistance match | ≤4Ω max difference between any two channels - critical for differential pair switching and matched filter banks |
| Low temperature drift of on-resistance | Stable RON across -40°C to +85°C - ensures consistent channel gain in automotive and industrial environments |
| High off-isolation | -60dB at 1MHz - prevents crosstalk between adjacent switched channels in multi-signal systems |
| Low charge injection | 1pC typical - minimizes voltage glitch on COM node during switching, essential for precision sample-and-hold |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612EUD+ | Same electrical specs, 14-pin TSSOP package - 5mm × 4.4mm vs. SO's 8.65mm × 3.9mm footprint | Better thermal performance and higher density layout; requires rework of land pattern | Select for PCB area-constrained designs where thermal dissipation >640mW is needed |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, but only NO configuration; 16-pin TSSOP; ±15V dual-supply capable | Not pin-compatible; lacks NC functionality; suited for high-precision, wide-supply applications | Choose when ultra-low on-resistance and dual-supply operation outweigh need for NC topology |
Compared with MAX4612ESD, MAX4612EUD+ offers identical switching performance in a smaller package with improved thermal resistance, while ADG1412BRUZ trades NC flexibility for lower RON and wider supply range - making MAX4612ESD optimal for cost-sensitive, mixed NO/NC routing in +2V to +12V single-supply systems.

FAQ
What is the maximum supply voltage rating for MAX4612ESD?
The absolute maximum V+ rating for MAX4612ESD is +13V referenced to GND. Operation above +12V is possible but requires strict adherence to bypassing (≥0.1µF ceramic capacitor at V+ pin) and thermal derating. Exceeding +13V risks permanent damage, especially under transient conditions or with ±10% tolerance supplies approaching 13.2V.
Does MAX4612ESD support bidirectional analog signal flow?
Yes, MAX4612ESD supports fully bidirectional analog signal flow on all COM/NO/NC terminals. Each switch channel conducts equally well in either direction, with identical on-resistance and leakage specifications regardless of signal polarity - a core feature of its CMOS transmission-gate architecture.
How does the NO/NC configuration of MAX4612ESD differ from MAX4610 and MAX4611?
MAX4612ESD integrates two normally open (NO) switches (pins 1, 8) and two normally closed (NC) switches (pins 3, 11), whereas MAX4610ESD has four NO switches and MAX4611ESD has four NC switches. This hybrid configuration allows fail-safe default signal paths combined with active-enable routing in a single package.
Can MAX4612ESD operate from a +3V supply, and what is its on-resistance at that voltage?
Yes, MAX4612ESD operates down to +2V supply. At +3V, typical on-resistance is 360Ω (max 450Ω), significantly higher than the 100Ω max at +5V. Designers must verify signal integrity and voltage drop in +3V applications - particularly in high-impedance sensor paths where RON-induced errors become dominant.
Is the MAX4612ESD pinout compatible with industry-standard analog switches like the 74HC4066?
No, MAX4612ESD is not pin-compatible with the 74HC4066. While functionally similar as quad SPST switches, MAX4612ESD uses a unique pin assignment (e.g., V+ at pin 14, GND at pin 7, NO/NC distributed across pins 1/3/8/11) versus the 74HC4066's standardized layout. Direct replacement requires PCB redesign.
