ADG714BRUZ 概要
An analog switch is an integrated semiconductor device that connects or disconnects signal paths under digital control. The ADG714 belongs to the CMOS analog-switch and interface-IC hierarchy, where matched low on-resistance and bidirectional conduction help preserve signal integrity in measurement, instrumentation, and communication equipment. Its serial control reduces the number of dedicated logic pins compared with an individually controlled switch array.
The ADG714 family provides complementary CMOS octal SPST switching, closely matched on-resistance across channels, and flat on-resistance over the full signal range. The verified source data identifies a 32 ns turn-on time, 18 ns turn-off time, a -2.5 V to 2.75 V supply specification, and operation from -40 °C to 85 °C. The 24-TSSOP package is surface mount and supports compact PCB layouts.
The three-wire serial interface uses shift-register data loaded into the device, allowing multiple switch states to be configured with a compact command structure. This interface is useful when the system already has a serial bus and needs repeatable routing of analog signals. Exact serial timing, logic levels, channel mapping, and electrical limits should be confirmed in the manufacturer datasheet.
Typical uses include signal multiplexing in automated test equipment, instrumentation signal routing, communication-channel selection, data-acquisition systems, and low-voltage analog front ends. Designers should account for supply voltage, signal range, on-resistance, switching time, logic compatibility, and unused-channel handling during layout and firmware design.
A critical layout practice is to keep analog signal traces short and route control signals away from sensitive paths. Confirm the manufacturer’s recommended decoupling and exposed-pin requirements before finalizing the PCB. This page combines verified manufacturer information, distributor data, pricing fields where available, and practical design guidance without filling unspecified parameters with guesses.

Automated Test Equipment Signal Routing
ADG714BRUZ fits automated test equipment that needs eight independently addressed analog paths in a compact 24-TSSOP package. Its verified 4.5 Ω on resistance, 32 ns turn-on time, and 18 ns turn-off time help preserve signal amplitude while changing routes. The 3-wire serial interface reduces control-pin count and is useful when the tester already communicates over a serial bus. Designers should still budget for switch capacitance, off leakage, and charge injection when specifying measurement accuracy.
おすすめ
Low-Voltage Data Acquisition
The ADG714BRUZ can route low-voltage analog inputs in data-acquisition systems where eight SPST channels and serial configuration simplify control wiring. Its bidirectional conduction allows signals to be connected without a fixed input or output orientation, while the specified -2.5 V to 2.75 V supply range supports compact dual-supply signal chains. Keep trace lengths short and provide stable bypassing near the device so switching transients do not disturb the source and load.
おすすめ
Instrumentation Signal Multiplexing
ADG714BRUZ is appropriate for instrumentation front ends that must select among several sensor or amplifier paths. The closely matched channel on resistance helps preserve consistency across the eight SPST switches, and the 4.5 Ω value provides a defined basis for calculating source loading. Because the switch is controlled serially, firmware can update multiple channels predictably. The system designer must verify signal amplitude, common-mode range, leakage, and channel-to-channel switching transients against the complete measurement chain.
おすすめ
Communication Channel Selection
The eight-channel SPST architecture makes ADG714BRUZ useful for selecting communication paths in compact low-voltage equipment. Its 32 ns turn-on and 18 ns turn-off characteristics can support controlled routing when the controller timing budget is designed around the serial-interface overhead. The 3-wire control method helps limit package pins compared with separate control lines. RF, high-speed digital, and high-impedance sensor applications still require package-level and datasheet validation for bandwidth and parasitics.
おすすめ
Battery-Powered Analog Front End
ADG714BRUZ can be used in battery-powered analog front ends when the signal system operates within the verified -2.5 V to 2.75 V supply range. The low-voltage CMOS design avoids requiring a high-voltage switch for appropriately scaled signals, while the 24-TSSOP package supports compact assembly. Supply current, off-state behavior, and power consumption were not supplied in the verified data and must be measured or obtained from the manufacturer before making battery-life claims.
おすすめ
Precision Analog Signal Conditioning
ADG714BRUZ is suitable for precision signal-conditioning paths where matching and predictable switching are important. The manufacturer description highlights closely matched on resistance and flat behavior over the full signal range, helping maintain channel consistency. Its 4.5 Ω on resistance should be included in the source/load calculation, and the circuit should provide adequate settling time after a 32 ns or 18 ns transition. Check leakage, charge injection, and noise specifications in the datasheet for the final accuracy budget.

設計ノート
Place the ADG714BRUZ close to the sources and loads it routes, and keep the eight analog paths short and appropriately terminated. Route the 3-wire serial control lines away from sensitive analog traces to reduce capacitive coupling and switching noise. Use a continuous ground reference, maintain the manufacturer’s recommended package land pattern, and verify the exposed or thermal-pad requirements in the official package drawing before fabrication.
Design the supply rails around the verified -2.5 V to 2.75 V specification and check absolute maximum limits in the manufacturer datasheet before applying transients. Place bypass capacitors close to the appropriate power pins and provide a clean return path for high-frequency switching current. Because supply-current, quiescent-current, and power-consumption values were not included in the supplied data, do not estimate battery life or thermal performance without the datasheet values.
Include the verified 4.5 Ω on resistance in the source/load network and calculate the resulting attenuation before selecting the switch. The manufacturer reports closely matched on resistance and flat behavior over the full signal range, which is useful for multichannel systems, but channel capacitance, leakage, and charge injection still affect settling and accuracy. Measure the complete signal path rather than relying only on the nominal resistance value.
