Product details
Overview
MAX4612CSD+T 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 is used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4612CSD+T datasheet, MAX4612CSD+T pinout, MAX4612CSD+T application, or MAX4612CSD+T equivalent, key selection criteria include verified on-resistance flatness (≤18Ω), off-leakage current (<2nA at +85°C), TTL/CMOS logic compatibility at +5V, and SO-14 package thermal performance (640mW at +70°C).
Technical Context
The MAX4612CSD+T implements four independent SPST switches in a single monolithic CMOS process, with two NO and two NC configurations controlled by separate digital inputs. Its architecture ensures matched on-resistance across all channels and flat on-resistance over the full analog signal range (0V to V+).
It supports rail-to-rail analog signals without level-shifting, features >2kV ESD protection per Method 3015.7, and maintains guaranteed logic thresholds (VIN_H = 2.4V, VIN_L = 0.8V) for TTL/CMOS compatibility when powered from +5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 100Ω at +5V supply - limits voltage drop and power loss in signal paths up to ±1mA load |
| On-Resistance Match (max) | 4Ω between channels - ensures consistent gain/attenuation across multiplexed sensor or audio channels |
| Off-Leakage Current (max) | 2nA at +85°C - preserves accuracy in high-impedance sample-and-hold or precision measurement nodes |
| Analog Signal Range | 0V to V+ - enables direct interface with unipolar sensors, DAC outputs, and ADC inputs without external biasing |
| Logic Compatibility | TTL/CMOS at +5V (VIN_H ≥ 2.4V, VIN_L ≤ 0.8V) - allows direct connection to microcontroller GPIO without level shifters |
| Supply Range | +2V to +12V single supply - supports operation from Li-ion batteries (3.0–4.2V) up to industrial 12V rails |
| Turn-On/Off Time | 65ns / 28ns typical - suitable for multiplexing audio-band signals (<20kHz) and fast data acquisition sampling |
Pinout & Package
MAX4612CSD+T is housed in a 14-pin narrow SO (Small Outline) package with standard 1.27mm pitch, exposed pad not present (unlike QFN variants), and rated for 640mW continuous power dissipation at +70°C with 8.00mW/°C derating above that temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog switch terminals - connect only when corresponding IN1/IN3 is HIGH |
| 3, 11 | NC2, NC4 | Normally closed analog switch terminals - disconnect only when corresponding IN2/IN4 is HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common analog I/O nodes - each pairs with one NO or NC terminal to form a complete SPST path |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive NO/NC state per truth table |
| 7 | GND | Digital and analog reference ground - must be low-impedance connection to minimize switching noise coupling |
| 14 | V+ | Positive supply for analog and digital circuitry - bypass with ≥0.1µF ceramic capacitor close to pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from 0V to V+ without clipping or distortion - eliminates need for external level-shifting circuitry |
| Guaranteed on-resistance flatness | ≤18Ω variation over full signal range - ensures minimal THD (<0.009%) in audio routing applications |
| Channel-to-channel on-resistance match | ≤4Ω max mismatch - critical for precision multiplexing in instrumentation and sensor arrays |
| Low off-leakage current | <2nA at +85°C - maintains integrity of high-Z sample-and-hold capacitors and low-current sensor interfaces |
| ESD robustness | >2kV per Method 3015.7 - reduces risk of field failure in handheld or industrial environments with frequent handling |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |
|---|---|
|
Use Scenario: Multiplexing microphone inputs or headphone outputs in portable medical monitors or wireless headsets. IC Role / Device Role / Timing Role: Quad SPST switch selectively connects analog audio paths under microcontroller GPIO control. Use Value: 100Ω on-resistance and <0.009% THD preserve signal fidelity; 2nA leakage prevents DC offset drift in AC-coupled paths. |
Use Scenario: Channel selection in 12-bit SAR ADC front-end for environmental sensor arrays (temperature, humidity, gas). IC Role / Device Role / Timing Role: Isolates individual sensor outputs before conditioning and digitization. Use Value: 4Ω on-resistance match ensures uniform gain scaling across channels; rail-to-rail support accommodates 0–3.3V sensor outputs directly. |
| Sample-and-Hold Circuits | Communication Signal Switching |
|
Use Scenario: Sampling analog sensor outputs into a hold capacitor prior to ADC conversion in energy-harvesting IoT nodes. IC Role / Device Role / Timing Role: Low-charge-injection (1–5pC) NO switch gates sampling phase with precise timing. Use Value: Minimal charge kickback preserves hold capacitor voltage accuracy; 65ns turn-on enables sub-15MHz sampling rates. |
Use Scenario: Selecting between RF transceiver baseband I/Q lines and calibration test points in cellular infrastructure modules. IC Role / Device Role / Timing Role: SPST switch isolates signal paths during self-test or antenna tuning sequences. Use Value: -60dB off-isolation at 1MHz suppresses crosstalk between active and idle paths; 300MHz bandwidth supports wideband IF routing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612CUD+ | Same electrical specs, but in 14-pin TSSOP (0.65mm pitch) instead of narrow SO (1.27mm pitch) | Requires PCB layout revision due to different footprint and thermal pad absence | Select for higher board density where reflow profile supports fine-pitch assembly |
| ADG1412BRUZ | Quad SPST, 1.8Ω typical on-resistance, but requires dual ±15V or single +36V supply; not +2V–+12V compatible | Not suitable for low-voltage battery systems; better for high-precision industrial test equipment | Choose only if ultra-low on-resistance and high-voltage tolerance outweigh supply compatibility constraints |
Compared with MAX4612CUD+, the MAX4612CSD+T offers identical switching performance but superior thermal dissipation (640mW vs. 500mW) in SO packaging, while ADG1412BRUZ trades low-voltage operability for lower on-resistance and higher voltage capability-making it unsuitable for direct replacement in +5V portable designs.

FAQ
What is the maximum supply voltage rating for MAX4612CSD+T?
The absolute maximum V+ rating for MAX4612CSD+T is +13V referenced to GND. Operation at +12V is fully specified and supported, but sustained use above +12.5V risks reliability degradation. The device must never experience V+ to GND differential exceeding 13.0V, especially under transient conditions like power-supply overshoot.
Does MAX4612CSD+T support rail-to-rail analog signals?
Yes, MAX4612CSD+T supports analog signal levels from 0V to V+ on all COM, NO, and NC terminals. This rail-to-rail capability is guaranteed across the full operating temperature range and supply voltage (2V to 12V), enabling direct interface with unipolar sensors, DACs, and ADCs without external bias networks.
What is the on-resistance match specification for MAX4612CSD+T?
MAX4612CSD+T guarantees a maximum on-resistance match of 4Ω between any two channels at +25°C and 100Ω max on-resistance at +5V. This ΔRON = RON(max) − RON(min) ≤ 4Ω ensures uniform signal attenuation across multiplexed paths, critical for precision instrumentation and multi-channel data acquisition.
Can MAX4612CSD+T operate from a +3V supply?
Yes, MAX4612CSD+T is fully functional at +3V. At this supply, on-resistance increases to 175–360Ω (typ/max), and logic thresholds adjust to VIN_H ≥ 1.0V and VIN_L ≤ 0.5V. All timing, leakage, and signal-range specifications remain valid, making it suitable for Li-ion or coin-cell powered devices.
Is the MAX4612CSD+T pinout compatible with industry-standard analog switches?
MAX4612CSD+T shares pinout compatibility with the 74HC4066 and MAX4066 in the 14-pin narrow SO package. Pin assignments for COM, NO/NC, IN, V+, and GND align functionally, allowing drop-in replacement in existing layouts - provided logic polarity and on-resistance requirements are verified for the target application.
