Product details
Overview
MAX4612EUD 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 GND to V+; used in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4612EUD datasheet, MAX4612EUD pinout, MAX4612EUD application, or MAX4612EUD equivalent, key selection criteria include its dual NO/NC configuration, guaranteed flat on-resistance over signal range, sub-2nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and TSSOP-14 packaging for space-constrained portable designs.
Technical Context
The MAX4612EUD integrates four independent SPST switches-two NO and two NC-each controlled by dedicated digital inputs (IN1–IN4), enabling simultaneous or selective signal path configuration without cross-talk coupling. Its CMOS architecture ensures rail-to-rail analog conduction (GND to V+) and supports single-supply operation from +2V to +12V.
On-resistance flatness is guaranteed ≤18Ω over the full signal range, and channel matching (ΔRON) is specified ≤4Ω at +5V, critical for precision multiplexing and sample-and-hold accuracy. Logic thresholds (VIN_H = 2.4V, VIN_L = 0.8V at +5V) ensure robust interfacing with standard TTL/CMOS microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max at +5V supply - ensures minimal signal attenuation in low-level analog paths |
| On-Resistance Match (ΔRON) | 4Ω max between channels - enables matched gain/attenuation across parallel signal paths |
| On-Resistance Flatness | 18Ω max over signal range - maintains consistent insertion loss across full analog input swing |
| Off-Leakage Current | 2nA max at TA = +85°C - preserves signal integrity in high-impedance sample-and-hold nodes |
| Analog Signal Range | GND to V+ - supports true rail-to-rail signal switching without clipping or distortion |
| Logic Compatibility | TTL/CMOS at +5V (VIN_H = 2.4V, VIN_L = 0.8V) - eliminates level-shifting in mixed-signal MCU interfaces |
| ESD Protection | >2kV per Method 3015.7 - enhances reliability in handheld and field-deployable equipment |
Pinout & Package
MAX4612EUD is housed in a RoHS-compliant 14-pin TSSOP package (U14+1), with exposed-pad variants reserved for QFN versions - this variant uses standard TSSOP without thermal pad.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog terminals - conduct only when corresponding INx = HIGH |
| 3, 11 | NC2, NC4 | Normally closed analog terminals - conduct only when corresponding INx = LOW |
| 2, 4, 9, 10 | COM1–COM4 | Common analog connection points - serve as shared I/O for each switch channel |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible logic signals enabling independent NO/NC state control |
| 7 | GND | Digital ground reference - must be tied to system ground for proper logic threshold referencing |
| 14 | V+ | Single positive supply - powers both analog and digital sections; range +2V to +12V |
Key Features
| Feature | Design Value |
|---|---|
| Dual NO/NC configuration | Two independently controllable NO and two NC switches in one IC - enables fail-safe signal routing and redundant path design |
| Rail-to-rail analog conduction | Supports signals from GND to V+ - eliminates need for external biasing in single-supply sensor or audio front-ends |
| Guaranteed on-resistance flatness | ≤18Ω variation over full signal range - ensures linear amplitude response in precision instrumentation |
| Low temperature drift leakage | <2nA off-leakage at +85°C - sustains hold accuracy in extended-temperature industrial data loggers |
| High ESD immunity | >2kV HBM - improves manufacturing yield and field reliability in unshielded portable assemblies |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |
|---|---|

IC Role / Device Role / Timing Role: Quad SPST analog switch providing isolated, low-distortion signal path selection under microcontroller control. Use Value: 0.009% THD+N at 2VP-P and 300MHz bandwidth preserve audio fidelity; 100Ω RON minimizes loading on high-Z sensor outputs. |
Use Scenario: Multiplexing thermocouple, RTD, or bridge sensor outputs into a single precision ADC in handheld test equipment. IC Role / Device Role / Timing Role: Precision analog switch enabling sequential sampling of up to four sensors with matched channel characteristics. Use Value: 4Ω max RON match and <2nA off-leakage prevent gain/offset errors and charge injection-induced settling delays. |
| Sample-and-Hold Circuits | Communication Signal Switching |

IC Role / Device Role / Timing Role: Low-crosstalk (−80dB) analog switch routing baseband or IF signals between transceiver chains. Use Value: −60dB off-isolation and 16pF COFF suppress inter-channel interference in multi-path receiver architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611EUD+ | Four NC-only switches (vs. MAX4612EUD's 2NO/2NC); identical RON, leakage, and timing specs | Suitable where default-closed signal paths are required for safety or power-on-state continuity | Select MAX4611EUD+ when fail-closed behavior is mandatory; not pin-compatible for NO/NC reassignment |
| ADG1412BRUZ | 4-channel, 2NO/2NC configuration; lower RON (4.7Ω typ), wider supply (±15V or +12V), higher cost | Better suited for high-precision, wide-dynamic-range instrumentation requiring sub-1Ω matching | Choose ADG1412BRUZ only if <5Ω RON and enhanced tempco performance justify premium pricing and layout change |
Compared with MAX4611EUD+, MAX4612EUD provides configurable path states essential for bidirectional signal routing; versus ADG1412BRUZ, it offers cost-effective +2V–+12V operation with sufficient precision for portable and industrial DAQ, but lacks extended voltage range and ultra-low RON.

FAQ
What is the operating temperature range for MAX4612EUD?
The MAX4612EUD is rated for operation from −40°C to +85°C, meeting extended industrial temperature requirements. This range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, and applies specifically to the E-grade TSSOP variant (MAX4612EUD+). The device maintains specified on-resistance, leakage, and timing performance across this full range.
Does MAX4612EUD support rail-to-rail analog signal switching?
Yes, MAX4612EUD supports rail-to-rail analog signal switching - its analog terminals (COM, NO, NC) handle voltages from GND to V+ without degradation. This is explicitly guaranteed in the Electrical Characteristics tables under "Analog Signal Range" and reinforced in the General Description. No external biasing or level-shifting is needed for signals spanning the full supply rails.
What is the maximum supply voltage for MAX4612EUD?
The absolute maximum supply voltage (V+) for MAX4612EUD is +13V, but the recommended operating range is +2V to +12V. Operation at +12V is fully characterized - on-resistance drops to 30Ω (typ), and logic thresholds shift to VIN_H = 4.0V / VIN_L = 0.8V. Exceeding +13V risks permanent damage, as stated in the Absolute Maximum Ratings table.
How does the 2NO/2NC configuration of MAX4612EUD differ from MAX4610 and MAX4611?
MAX4612EUD integrates two normally open (NO) and two normally closed (NC) switches, whereas MAX4610EUD has four NO switches and MAX4611EUD has four NC switches. This hybrid configuration allows flexible signal routing - e.g., one path active by default (NC), another enabled on demand (NO) - enabling fail-safe or power-gated topologies not possible with uniform-switch families.
Is MAX4612EUD pin-compatible with industry-standard analog switches?
MAX4612EUD is pin-compatible with the 74HC4066 and MAX4066 in its 14-pin TSSOP package, sharing identical pin assignments for V+, GND, COMx, NOx/NCx, and INx. This allows drop-in replacement in existing layouts designed for those parts, provided the 2NO/2NC functionality meets the system's signal path requirements - no PCB changes are needed.
