Additional Details

The IXYS PAA161 typically requires a control voltage between 3V and 5V DC and can switch analog signals up to ±15V. Its compact package makes it suitable for high-density board layouts. The relay's design minimizes capacitive coupling, reducing signal distortion at higher frequencies. The PAA161 is often used in applications where maintaining signal integrity is critical, such as in medical instrumentation and precision measurement systems. Its combination of low on-resistance, low leakage current, and high isolation makes it a superior choice for analog signal switching compared to traditional mechanical relays.
