TCA785 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a decoupling capacitor (e.g., 100nF) close to the VCC pin.
  • Choose R1 and R2 resistors based on the desired gain and bandwidth. Select C1 and C2 capacitors based on the desired cutoff frequency and noise filtering. Use a 1% tolerance for resistors and a 10% tolerance for capacitors.
  • The maximum allowed voltage on the input pins is VCC + 0.3V. Exceeding this voltage may damage the device.
  • Use a shielded enclosure, keep the PCB away from radiating sources, and use a common-mode choke or ferrite bead on the input lines. Ensure proper grounding and decoupling to minimize electromagnetic radiation.
  • The thermal resistance (RthJA) of the TCA785 package is approximately 40 K/W. Ensure proper heat sinking and thermal management to prevent overheating.
