Product details
Overview
MAX4066AMJD from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch rated for operation from −55°C to +125°C, featuring 45Ω max on-resistance at 12V, 2Ω max channel-to-channel on-resistance matching, and 100pA max COM off-leakage current at +25°C. It supports bilateral signal routing in low-distortion audio, battery-powered instrumentation, and high-reliability industrial data-acquisition systems.
For engineers reviewing the MAX4066AMJD datasheet, MAX4066AMJD pinout, MAX4066AMJD application, or MAX4066AMJD equivalent, key selection criteria include guaranteed −55°C to +125°C operation, 2Ω matching for precision multiplexing, 100pA leakage for ultra-low-power hold circuits, and CERDIP package suitability for harsh-environment PCB mounting.
Technical Context
The MAX4066AMJD implements four independent SPST analog switches using complementary MOSFET pairs per channel, enabling bidirectional signal flow with rail-to-rail analog voltage handling (0V to V+). Its logic interface accepts TTL/CMOS-compatible input levels, eliminating level-shifting requirements across 3V, 5V, and 12V supply configurations.
Designed for signal integrity in wideband applications, it delivers >100MHz on-channel bandwidth, −86dB crosstalk, and −58dB off-isolation at 1MHz, while maintaining 0.03% THD for audio-grade switching. The device's charge injection (≤10pC) and on-resistance flatness (≤6Ω over full signal range) ensure minimal transient error in sample-and-hold and precision multiplexer topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp Range | −55°C to +125°C - qualified for aerospace, downhole, and military embedded systems requiring extended thermal stability. |
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures ≤0.5% gain error in 1kΩ sensor signal paths at full-scale voltage. |
| Channel Matching (∆RON) | 2Ω max - enables <0.2% relative gain tracking across channels in multi-sensor ADC front-ends. |
| COM Off-Leakage Current | 100pA max at +25°C - supports >100-second hold time in 10nF sample capacitors without significant droop. |
| Supply Voltage Range | +2.0V to +16V - allows direct integration with Li-ion (3.7V), 5V logic rails, and 12V industrial buses without regulators. |
| Bandwidth | >100MHz - preserves rise/fall times <3.5ns for digital control signals and baseband video routing. |
| THD | 0.03% - meets CD-quality audio switching requirements up to 20kHz with negligible harmonic generation. |
Pinout & Package
MAX4066AMJD is supplied in a 14-pin CERDIP (Ceramic Dual-In-Line Package) with hermetic sealing, 0.300-inch width, and lead finish suitable for high-reliability solder reflow or wave processes. Pin 1 is top-left corner (notch side), with GND at pin 7 and V+ at pin 14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - connect to signal sources; open-circuit when INx = L, conductive when INx = H. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - bidirectional path between NOx and system signal chain; handles 0V to V+ voltages. |
| 5, 6, 12, 13 | IN1–IN4 | TTL/CMOS logic inputs - drive corresponding switch ON/OFF; compatible with 3.3V/5V microcontrollers without pull-ups. |
| 7 | GND | Analog/digital reference ground - must be low-impedance connection to minimize noise coupling into analog paths. |
| 14 | V+ | Positive supply - powers internal switch FETs and logic; also defines analog signal ceiling (0V to V+). |
| 11, 3 | N.C. | No internal connection - left unconnected; no routing or termination required on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed channel matching | 2Ω max ∆RON ensures consistent gain scaling across all four switches in multi-channel data acquisition. |
| Ultra-low leakage | 100pA COM off-leakage enables >100-second hold time in 10nF sampling capacitors for precision SAR ADC interfaces. |
| Rail-to-rail analog range | 0V to V+ signal handling supports full utilization of ADC input ranges without external clamping diodes. |
| High off-isolation | −58dB at 1MHz prevents crosstalk-induced measurement errors in adjacent channels of sensor multiplexers. |
| Low distortion | 0.03% THD maintains fidelity in audio routing paths and prevents harmonic contamination in sensitive analog front-ends. |

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 |
|---|---|---|---|
| MAX4066MJD | Same CERDIP package and −55°C to +125°C rating, but MAX4066 (non-A) variant with 4Ω max channel matching and 1nA COM off-leakage. | Acceptable where <0.5% inter-channel gain variation is tolerable and leakage >100pA does not impact hold-time requirements. | Select MAX4066MJD only if cost sensitivity outweighs precision leakage/matching needs in non-critical signal paths. |
| ADG1414BRUZ | 16-pin TSSOP, ±15V dual-supply capable, 1.8Ω RON matching, but only rated −40°C to +125°C and 250pA leakage. | Suitable for bipolar signal routing but lacks guaranteed −55°C performance and hermetic reliability for space/aerospace use. | Choose ADG1414BRUZ only when dual-supply operation or lower on-resistance is prioritized over extreme cold-start capability. |
Compared with MAX4066MJD and ADG1414BRUZ, the MAX4066AMJD uniquely combines hermetic CERDIP packaging, −55°C start-up assurance, 2Ω matching, and 100pA leakage-making it the sole option for precision, ultra-low-power, extreme-temperature multiplexing where parameter drift must be minimized across full military temperature range.

FAQ
What is the maximum operating temperature range for the MAX4066AMJD?
The MAX4066AMJD is fully specified from −55°C to +125°C. This extended temperature range is validated per MIL-STD-883 test methods and applies to all electrical parameters including on-resistance, leakage, and switching speed. The MAX4066AMJD achieves this via CERDIP packaging and process-level qualification, making it suitable for deployment in engine compartments, downhole tools, and space-constrained industrial controllers where ambient extremes occur.
Is the MAX4066AMJD pin-compatible with the standard 74HC4066?
Yes, the MAX4066AMJD is pin-compatible with the industry-standard 74HC4066 in 14-pin DIP and SO packages-but the MAX4066AMJD uses a 14-pin CERDIP package with identical pinout mapping (IN1–IN4, COM1–COM4, NO1–NO4, GND, V+). While footprint matches, designers must verify that CERDIP thermal and mechanical properties meet board-level reliability requirements, especially under thermal cycling.
What is the guaranteed on-resistance matching between channels for the MAX4066AMJD?
The MAX4066AMJD guarantees ≤2Ω difference between maximum and minimum on-resistance (∆RON) across all four channels at V+ = 12V and TA = TMIN to TMAX. This specification is 100% tested and ensures consistent signal attenuation across multiplexed paths-critical for ratio-metric measurements in sensor arrays and precision ADC front-ends where channel-to-channel gain error must remain below 0.2%.
Does the MAX4066AMJD support single-supply operation?
Yes, the MAX4066AMJD operates from a single positive supply ranging from +2.0V to +16V. It requires no negative rail and supports analog signal voltages from 0V to V+, enabling direct interfacing with unipolar sensors, microcontroller ADCs, and rail-to-rail op-amps. At 3V supply, on-resistance is 170Ω max; at 12V, it drops to 45Ω max-providing design flexibility across low-voltage portable and high-voltage industrial systems.
What package type is used for the MAX4066AMJD?
The MAX4066AMJD is supplied exclusively in a 14-pin CERDIP (Ceramic Dual-In-Line Package) with 0.300-inch body width, hermetically sealed construction, and gold-plated leads. This package provides superior moisture resistance, thermal stability, and long-term parameter retention compared to plastic DIP or SO packages-making it ideal for mission-critical applications in aerospace, defense, and energy exploration where field failure is unacceptable.
