Product details
Overview
MAX4612CUD+ 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 TTL/CMOS logic compatibility in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4612CUD+ datasheet, MAX4612CUD+ pinout, MAX4612CUD+ application, or MAX4612CUD+ equivalent, key selection criteria include guaranteed on-resistance flatness (18Ω max), <2nA off-leakage at +85°C, 300MHz on-channel bandwidth, and TSSOP-14 package compatibility with space-constrained portable designs.
Technical Context
The MAX4612CUD+ implements four independent CMOS transmission gates controlled by separate digital inputs, each supporting bidirectional analog signal flow with no polarity restriction. Its architecture guarantees matched on-resistance across all four switches and maintains flat on-resistance over the full 0V to V+ signal range.
Logic inputs accept standard TTL/CMOS thresholds (0.8V low / 2.4V high at +5V), enabling direct interface with microcontrollers without level-shifting. The device features internal ESD protection (>2kV per Method 3015.7) and supports rail-to-rail operation without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct use in 3.3V, 5V, and 9V battery systems without regulation |
| On-Resistance (max) | 100Ω at +5V - ensures minimal voltage drop and signal attenuation in precision sensor multiplexing |
| On-Resistance Match | 4Ω max between channels - critical for matched gain paths in instrumentation amplifier front-ends |
| Off-Leakage Current | 2nA at +85°C - preserves accuracy in high-impedance sample-and-hold circuits |
| Bandwidth | 300MHz - supports audio, video, and medium-speed data signals without roll-off |
| Charge Injection | 5pC max - limits voltage glitch in switched-capacitor and ADC input conditioning stages |
| ESD Protection | >2kV per Method 3015.7 - reduces need for external transient suppression in handheld equipment |
Pinout & Package
MAX4612CUD+ is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package) with exposed pad (RoHS-compliant, lead-free). Package dimensions: 5.0mm × 4.4mm × 1.1mm, pitch 0.65mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog terminals - connect only when corresponding INx is HIGH; used for default-open signal paths |
| 3, 11 | NC2, NC4 | Normally closed analog terminals - remain connected until corresponding INx goes HIGH; used for default-closed fail-safe paths |
| 2, 4, 9, 10 | COM1–COM4 | Common analog nodes - bidirectional connection points shared between NO/NC and switch control logic |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive respective NO/NC switches ON/OFF independently |
| 7 | GND | Digital ground reference - must be tied to system ground plane for stable logic thresholds and leakage control |
| 14 | V+ | Positive supply - powers both analog switch core and logic interface; requires local 0.1µF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Two NO + two NC configuration | Enables mixed-signal routing topologies - e.g., simultaneous enable of primary path (NO) and disable of backup path (NC) in redundancy switching |
| Rail-to-rail signal handling | Supports full V+ to GND analog swing without clipping - essential for unipolar sensor outputs and DAC buffers |
| Guaranteed on-resistance flatness | 18Ω max variation across 0V–V+ range - minimizes harmonic distortion in audio signal chains |
| TTL/CMOS logic compatibility | Fixed 0.8V/2.4V thresholds at +5V - eliminates need for external level translators in MCU-connected systems |
| Automotive-grade variants available | Extended -40°C to +125°C versions exist (e.g., MAX4612AUD+) - confirms robust process design applicable to industrial environments |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611CUD+ | Four NC-only switches (no NO functionality); identical RON, leakage, and timing specs | Suitable only where default-closed behavior is required (e.g., safety interlock paths) | Select MAX4611CUD+ when all four channels must remain conductive until actively disabled |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON at +5V but higher 15nA leakage at +85°C; uses 16-pin TSSOP | Better on-resistance for high-precision current sensing, but higher leakage limits use in ultra-low-power sampling | Choose ADG1412BRUZ only if sub-2Ω RON is mandatory and leakage budget allows >7× increase over MAX4612CUD+ |
Compared with MAX4611CUD+, the MAX4612CUD+ provides flexible mixed NO/NC routing for fault-tolerant signal management; versus ADG1412BRUZ, it trades lower leakage and smaller footprint for moderately higher on-resistance - making it optimal for battery life–critical, moderate-accuracy applications.

FAQ
What is the maximum supply voltage rating for MAX4612CUD+?
The absolute maximum supply voltage (V+) for MAX4612CUD+ is +13V referenced to GND. Operation above +12V is possible but requires strict adherence to layout guidelines - including placement of a minimum 0.1µF ceramic bypass capacitor directly at the V+ pin. Exceeding +13V risks permanent damage, even momentarily.
Does MAX4612CUD+ support true bidirectional analog signal flow?
Yes, MAX4612CUD+ supports fully bidirectional analog signal flow on all COM/NO/NC terminals. Each switch functions identically regardless of signal direction - enabling use in both source-driven and load-driven configurations without performance degradation or polarity restrictions.
Can MAX4612CUD+ operate from a 3.3V supply?
Yes, MAX4612CUD+ is fully specified down to +2V supply. At +3.3V, on-resistance increases to 175Ω (typical), with guaranteed match ≤10Ω and off-leakage <2nA at +85°C. Logic inputs remain compatible due to fixed 0.8V/2.4V thresholds - no level shifting needed for 3.3V MCU interfaces.
What is the thermal performance of MAX4612CUD+ in TSSOP package?
In its 14-pin TSSOP package, MAX4612CUD+ has a thermal resistance θJA of 158°C/W. At maximum continuous power dissipation (500mW at +70°C ambient), junction temperature rises ~79°C above ambient - well within safe operating limits for commercial-grade use. Derating begins above +70°C at 6.3mW/°C.
Is the exposed pad on MAX4612CUD+ electrically connected?
No - the exposed pad on MAX4612CUD+ is not internally connected to any die node. Per Maxim's datasheet, it must be soldered to the PCB's V+ plane or a dedicated copper pour tied to V+ to improve thermal performance and EMI immunity. Leaving it floating degrades thermal resistance and may compromise long-term reliability.
