ADG1208YRUZ-REEL7 Overview
An analog multiplexer is a semiconductor switch that routes one of multiple analog input signals to a single output line under digital control. MUXes belong to the broader category of analog switches and multiplexers, which sit under interface ICs and are essential building blocks in data acquisition (DAQ), instrumentation, audio routing, and automatic test equipment (ATE). The ADG1208's iCMOS process combines high-voltage CMOS with submicron CMOS, providing low power consumption, low on-resistance, and high switching speed in a small footprint.
Key features include 200 ohm on-resistance (160 ohm per third-party sources), 5 ohm on-resistance flatness, +/-15 V dual supply operation, 1 pC charge injection, 2 pF off capacitance, 75 dB off-isolation, and 60 ns transition time. The device also offers break-before-make switching, rail-to-rail operation, 3 V logic-compatible digital inputs, and fully specified performance with +/-5 V, +5 V, +/-12 V, or +12 V supplies.
The ADG1208 employs parallel CMOS switches with parasitic-junction-isolated bodies, enabling low charge injection and low capacitance. The wide supply range supports industrial signal levels up to +/-15 V while the 3 V logic interface allows direct connection to modern microcontrollers, FPGAs, and ADCs without level shifters.
Typical applications include data acquisition front-ends, sample-and-hold systems, PLC analog input modules, ATE signal routing, audio/video signal switching, and battery-powered instrumentation. The TSSOP-16 footprint suits space-constrained PCB designs.
When designing with the ADG1208, add 0.1 uF bypass capacitors near each supply pin and ensure unused digital address lines are tied to GND or VDD to avoid floating-state channel selection. The break-before-make architecture prevents momentary shorting between channels during switching transitions.

Typical Applications
ADG1208YRUZ-REEL7 is suitable for 6 applications: Data Acquisition (DAQ) Front-End, Programmable Logic Controller (PLC) Analog Input Module, Automatic Test Equipment (ATE) Signal Routing, Audio/Video Signal Routing, Battery-Powered Instrumentation, Medical Monitoring Equipment.
Data Acquisition (DAQ) Front-End
The ADG1208YRUZ-REEL7 is a strong fit for multi-channel DAQ front-ends where 8 analog sensor inputs must be sampled sequentially by a single ADC. Its 1 pC charge injection minimizes the switching transients seen by the ADC input, reducing settling-time overhead and improving effective sample rate. The 200 ohm Ron and 5 ohm flatness introduce only modest insertion loss and gain error, which are easily calibrated out. Compared with a relay-based MUX, the iCMOS switch offers >10x faster channel switching (150 ns vs multi-ms relay actuation), unlimited mechanical lifetime, and lower BOM cost. Typical placement: between the sensor signal-conditioning network and the ADC driver/buffer, with the 3-bit address lines driven by an FPGA or microcontroller GPIO. Verify that source impedance plus Ron does not exceed the ADC's maximum input impedance spec.
Recommended
Programmable Logic Controller (PLC) Analog Input Module
In industrial PLC analog input subsystems, the ADG1208YRUZ-REEL7 multiplexes 8 field-sensor signals (4-20 mA, 0-10 V, thermocouple, RTD) into a single conditioning chain. Its +/-15 V supply tolerance handles industrial signal levels directly, while 75 dB off-isolation prevents channel-to-channel crosstalk that would corrupt precision measurements. The break-before-make switching architecture eliminates momentary shorting between adjacent channels, protecting upstream sensor electronics. The iCMOS process ensures low power dissipation suitable for 4-channel and 8-channel PLC modules where thermal budget is tight. The TSSOP-16 footprint saves PCB area versus legacy SOIC-16, supporting miniaturized I/O modules. Place 100 nF ceramic bypass capacitors on VDD and VSS within 5 mm of the supply pins for noise immunity in electrically noisy industrial environments.
Recommended
Automatic Test Equipment (ATE) Signal Routing
In ATE pin-electronics and source-measurement units, the ADG1208YRUZ-REEL7 routes up to 8 stimulus or measurement signals to a single device-under-test (DUT) pin. Its 1 pC low charge injection is essential when switching sensitive analog nodes where transient spikes would cause false DUT failures. The 150 ns tON/tOFF enables rapid reconfiguration of test vectors in production test programs, reducing overall test time. Rail-to-rail signal handling supports test voltages up to +/-15 V without external clamping. The 3 V logic interface works with modern ATE controllers without level shifters. Note: for very-low-current measurements (<1 nA), the 200 ohm Ron and leakage currents may introduce errors - consider an electromechanical relay or a specialty low-leakage MUX in such cases.
Recommended
Audio/Video Signal Routing
In professional audio mixers, broadcast routers, and video switching systems, the ADG1208YRUZ-REEL7 routes up to 8 line-level audio channels or composite video signals with minimal degradation. The 75 dB off-isolation at audio frequencies prevents channel-to-channel crosstalk that would manifest as audible bleed or video ghosting. Its 200 ohm Ron is compatible with typical 10k ohm audio source impedances, attenuating signals by less than 2%. Rail-to-rail operation supports professional +4 dBu and -10 dBV levels. The 3 V logic compatibility allows direct connection to digital audio workstations or HDMI switch controllers. For 600 ohm professional audio, the 200 ohm Ron may slightly attenuate signal; consider the MAX308CUE+ alternative with lower Ron for that specific case.
Recommended
Battery-Powered Instrumentation
In portable battery-powered test instruments and handheld meters, the ADG1208YRUZ-REEL7 offers low quiescent current and high switching speed. The iCMOS process draws minimal current in both static and switching states, preserving battery life compared with bipolar-junction MUXes. Single +12 V supply operation enables direct connection to a 3-cell Li-ion battery stack (12.6 V max). The TSSOP-16 package and minimal external component count (no charge pump, no level shifters) reduce overall BOM area and cost - critical for space-constrained handheld designs. The 150 ns switching speed supports >1 MHz effective scan rate for fast waveform capture. For ultra-low-power designs (sub-1 uA quiescent), consider a different MUX with nanoamp quiescent current; the ADG1208 is optimized for switching performance, not quiescent current.
Recommended
Medical Monitoring Equipment
In multi-parameter patient monitors (ECG, EEG, SpO2, temperature), the ADG1208YRUZ-REEL7 routes up to 8 sensor channels into a shared analog front-end, reducing board area and cost. The 1 pC low charge injection is critical for medical safety - switching transients cannot cause artifact on sensitive biopotential signals that could trigger false alarms. The 75 dB off-isolation prevents leakage between channels that could cross-contaminate vital-sign measurements. Rail-to-rail operation supports the +/-5 V typical biopotential signal range. The TSSOP-16 footprint and 3 V logic interface suit modern compact medical IoT devices. Verify compliance with IEC 60601-1 patient-leakage requirements at the system level; the IC itself does not have medical certifications.

Design Notes
Place 100 nF ceramic bypass capacitors as close as possible (within 5 mm) to the VDD (pin 15) and VSS (pin 6) supply pins. For noisy industrial environments, add a 10 uF bulk tantalum or ceramic capacitor in parallel. The iCMOS process draws minimal supply current, but transient current during switching can inject noise into sensitive analog rails - adequate decoupling prevents this. Source: Analog Devices ADG1208 datasheet, Application Information section.
Unused digital address lines (A0, A1, A2) and the EN pin must be tied to a valid logic level (GND or VDD), not left floating. A floating address line can cause the MUX to intermittently select two channels simultaneously or enter an undefined state, leading to measurement errors and unpredictable behavior. The EN pin should be tied high (VDD) if channel disabling is not used. The break-before-make architecture prevents momentary shorting between adjacent Sx channels during address transitions.
Use a continuous ground plane on the layer beneath the ADG1208YRUZ-REEL7 to minimize ground bounce and provide thermal dissipation. Keep digital address line traces short and routed away from analog signal traces to reduce digital-to-analog crosstalk. Route S1-S8 source traces symmetrically to minimize channel-to-channel Ron mismatch. The exposed thermal pad (if present in TSSOP package variant) should be soldered to a copper pour for improved thermal performance.
The 200 ohm Ron introduces a voltage divider effect with the source and load impedances. For a 10 kohm source and high-impedance ADC input, the signal attenuation is approximately 2% - negligible for most applications. For 600 ohm audio source impedance, attenuation increases to ~25%, which is unacceptable; use a buffer amplifier or choose a lower-Ron MUX (e.g., MAX308CUE+). The 5 ohm Ron flatness guarantees <1% gain error across the signal range when used with >5 kohm source impedance.
