ADG1408YRUZ-REEL7 概述
An analog multiplexer (mux) is an analog switch array that time-multiplexes multiple analog input signals onto a single output line, allowing a microcontroller or ADC to sequentially sample many channels using only one ADC input. In the broader hierarchy, the ADG1408 belongs to the analog switch family, itself a subset of signal routing and interface ICs. The iCMOS (industrial CMOS) process used by Analog Devices combines high-voltage bipolar, CMOS, and DMOS transistors on a single die, enabling ±15 V / +12 V / ±5 V dual-supply operation while keeping leakage and Ron low.
Key differentiating specifications include a 4.7Ω typical on-resistance, ±15 V dual-supply tolerance, low power consumption, latch-up proof construction, and break-before-make switching that prevents momentary shorting of input channels during channel transitions. The 3-bit binary address logic allows a simple GPIO or decoder to drive selection.
The iCMOS architecture delivers high voltage tolerance with low Ron and low charge injection, making the ADG1408 suitable for industrial process control, instrumentation, and audio routing. Unlike low-voltage CMOS muxes (e.g., 4051-family parts limited to ~5 V), the iCMOS process lets designers route ±10 V or ±15 V signals directly without external level shifting.
Typical applications include industrial process control PLCs, multi-channel data acquisition (DAQ) front-ends, audio/video signal routing, ATE (automatic test equipment) pin switching, and medical monitoring multiplexers. It is commonly paired with 16/18-bit ADCs to expand channel count.
A key design consideration is supply sequencing: while iCMOS parts tolerate standard supplies, designers should add 100 nF decoupling close to VDD/VSS and consider ESD protection on field-side inputs. Break-before-make behavior eliminates cross-couples but limits simultaneous-channel sampling, so for simultaneous sampling use a per-channel amplifier + SAR front-end instead.

典型应用
ADG1408YRUZ-REEL7 适用于 7 应用s: Industrial Process Control PLCs, Multi-Channel Data Acquisition (DAQ) Front-End, Audio/Video Signal Routing, Automatic Test Equipment (ATE) Pin Switching, Medical Monitoring Multiplexers, Battery Cell Monitoring in BMS, Communication Test and Switching.
Industrial Process Control PLCs
The ADG1408YRUZ-REEL7 is widely used in industrial PLC analog input modules where multiple field sensors (4-20 mA, ±10 V thermocouples, pressure transducers) must be sequentially routed to a single 16/18-bit ADC. Its ±15 V supply tolerance allows direct multiplexing of ±10 V industrial signals without level-shifting. With 4.7Ω Ron and break-before-make switching, channel-to-channel settling is fast and channel cross-couples are below the ADC noise floor, enabling high-accuracy multiplexed measurement of up to 8 single-ended analog inputs per chip with minimal guardband for settling time.
推荐
Multi-Channel Data Acquisition (DAQ) Front-End
In data acquisition systems, the ADG1408YRUZ-REEL7 expands the channel count of a single high-resolution ADC by time-multiplexing 8 analog sources onto one ADC input. Its low 4.7Ω Ron minimizes insertion loss, while break-before-make switching prevents momentary cross-channel shorts. Combined with 16- or 18-bit successive-approximation ADCs, the ADG1408 enables 8-channel systems without the cost of one ADC per channel. The iCMOS process delivers low charge injection, which is critical for fast settling into the ADC's sample-and-hold capacitor.
推荐
Audio/Video Signal Routing
The ADG1408YRUZ-REEL7 serves as a low-distortion audio/video signal router in professional AV equipment, mixing consoles, and test benches. Its ±15 V supply range lets it pass balanced ±10 V pro-audio line signals with low Ron-induced distortion. Break-before-make switching prevents clicks and pops during source switching. With 4.7Ω Ron, signal attenuation across the switch is negligible for line-level audio (typically <0.01 dB insertion loss). The 16-TSSOP footprint allows dense routing matrices in compact audio equipment.
推荐
Automatic Test Equipment (ATE) Pin Switching
In ATE systems, the ADG1408YRUZ-REEL7 multiplexes one of 8 instrument channels (DMM, scope, signal source) to a single DUT pin under test. Its low leakage and low Ron are critical for accurate measurement at microamp/nanovolt signal levels. The iCMOS process provides latch-up immunity, important when the DUT outputs voltages beyond the supply rails during ESD events. The 3-bit binary address can be driven directly from the ATE controller's GPIO, simplifying test program sequencing for up to 8 source-measure channels per chip.
推荐
Medical Monitoring Multiplexers
The ADG1408YRUZ-REEL7 is used in patient monitoring equipment to multiplex multiple biopotential signals (ECG leads, EMG channels, EEG electrodes) onto a single high-resolution ADC for processing. Its low noise and low Ron preserve signal fidelity for diagnostic-grade measurements. The iCMOS process offers low charge injection, which minimizes settling artifacts in the sample-and-hold of precision medical ADCs. The 16-TSSOP package enables compact, multi-channel patient monitor designs where board space is constrained.
推荐
Battery Cell Monitoring in BMS
The ADG1408YRUZ-REEL7 routes one of 8 individual battery cell voltages to a single ADC in multi-cell battery management systems (BMS). Its ±15 V supply tolerance handles 12V, 24V, and 48V battery stacks, while the 4.7Ω Ron has negligible impact on the high-impedance ADC input. Break-before-make switching prevents momentary shorts between adjacent battery cells during channel transitions. The 16-TSSOP package allows high-density cell monitoring boards with one mux per 8-cell module in lithium-ion battery packs.
推荐
Communication Test and Switching
In telecom test equipment and base station maintenance, the ADG1408YRUZ-REEL7 routes one of 8 RF or baseband test signals to a single test instrument for verification. Its low Ron minimizes signal attenuation, important for accurate RF level measurement. The iCMOS process allows the mux to handle signals well above the supply rails, simplifying signal conditioning. Break-before-make action prevents signal cross-talk during channel transitions in sequential test routines for 8-port communications equipment.

设计说明
Place 100 nF decoupling capacitors as close as possible to the VDD (pin 3) and VSS (pin 8) pins to suppress switching transients. For multi-mux designs, add a 10 µF bulk capacitor on the supply rail shared by all muxes. The iCMOS process draws minimal quiescent current but transient currents during channel transitions can corrupt adjacent analog signals if decoupling is inadequate.
Keep analog input traces (S1-S8) and the common output (D, pin 14) routed symmetrically to minimize Ron mismatch between channels. Avoid routing digital address lines (A0/A1/A2 and EN) parallel to or crossing analog traces - use a ground guard trace between digital and analog sections. The exposed thermal pad (if present in TSSOP-EP variant) should be soldered to a grounded copper pour for thermal dissipation, although the ADG1408YRUZ (16-TSSOP, no EP) does not have a thermal pad.
The ADG1408's break-before-make switching prevents channel cross-talk but limits use in simultaneous sampling applications. For simultaneous sampling, use a per-channel amplifier + SAR ADC architecture instead of a mux. Account for mux settling time (typically 1-2 µs to 0.1% with 1 nF load) when calculating the ADC acquisition time budget - set the ADC sample-and-hold acquisition window to at least 2x the mux settling time to avoid gain errors.
Do not apply signals to S1-S8 or D that exceed VDD or fall below VSS by more than 0.3 V when the device is unpowered - this can cause latch-up due to internal ESD diode conduction. Always power the ADG1408 before applying analog signals, or add external clamping diodes. The EN pin (pin 2) must be driven high for normal operation; leaving EN floating puts the device in an undefined state that may draw excess supply current.
