ISL84781IRZ - Renesas Electronics

Description: The Intersil ISL84781 device contains precision, bidirectional, analog switches configured as an 8-channel multiplexer/demultiplexer. It is designed to operate from a single +1. 6V to +3. 6V supply. The device has an inhibit pin to simultaneously open all signal paths. ON-resistance is 0. 4Ω with a +3. 0V supply and 0. 55Ω with a single +1. 8V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 4nA max at +25°C or 40nA max at +85°C with a +3. 3V supply. All digital in

ISL84781IRZ Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL84781IRZ involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure the stability of the output voltage, it is essential to use the recommended output capacitor values and types, and to place them as close to the IC as possible. Additionally, the input capacitor should be selected based on the input voltage and current requirements.
  • The ISL84781IRZ can handle a maximum input voltage of 18V, but it is recommended to operate it within the specified input voltage range of 2.7V to 15V for optimal performance and reliability.
  • The ISL84781IRZ is rated for operation up to 125°C, but it is essential to ensure that the IC is properly heatsinked and that the thermal design is adequate to prevent overheating.
  • To troubleshoot issues with the ISL84781IRZ, start by checking the input voltage, output voltage, and current consumption. Verify that the capacitors are properly selected and placed, and that the PCB layout is correct. Use an oscilloscope to check for oscillations or noise on the output.
