Frequently Asked Questions
What is the on-state resistance and bandwidth of the TS5A4595DCKRE4?
The TS5A4595DCKRE4 has a typical on-state resistance of 8 ohms and a nominal bandwidth of 450 MHz. The low on-resistance minimizes signal voltage drop and distortion across the switch, while the 450 MHz bandwidth enables use in high-frequency analog and RF signal routing applications up to the UHF frequency band.
What is the off-state isolation of the TS5A4595DCKRE4?
The TS5A4595DCKRE4 provides 82 dB nominal off-state isolation, meaning that when the switch is open, signals on one side are attenuated by more than 82 dB before reaching the other side. This high isolation is critical for preventing signal crosstalk in audio switching, RF multiplexing, and precision analog circuits where channel-to-channel leakage must be minimized.
What supply voltages does the TS5A4595DCKRE4 support?
The TS5A4595DCKRE4 operates with a 3.3V or 5V supply voltage and accepts analog signal inputs up to a maximum of 5.5V. This dual supply voltage compatibility makes it easy to interface with both 3.3V microcontroller systems and legacy 5V analog circuits without additional level translation components.
What is the normal position and channel configuration of the TS5A4595DCKRE4?
The TS5A4595DCKRE4 is configured as a single-channel (1 function, 1 channel) SPST switch with a normally closed (NC) default position. In the NC state the switch conducts without any control signal applied, which can simplify fail-safe designs where signal continuity must be maintained if the control signal is lost.
What applications is the TS5A4595DCKRE4 suitable for?
The TS5A4595DCKRE4 is ideal for audio signal routing in smartphones and portable media players, antenna switching in Bluetooth and Wi-Fi modules, sensor multiplexing in medical diagnostic devices, and signal path selection in automated test equipment. Its 8-ohm on-resistance and 450 MHz bandwidth also make it a good choice for video signal switching and precision data acquisition channel selection in industrial instruments.
