BM6104FV-CE2 - ROHM Semiconductor

BM6104FV-CE2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A thermal pad is recommended under the IC to improve heat dissipation. A 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer is recommended.
• How do I ensure stable operation with a single power supply?
  To ensure stable operation, a decoupling capacitor (e.g., 10uF) should be connected between VCC and GND as close to the IC as possible. Additionally, a 0.1uF capacitor can be added between VCC and AVCC for further noise reduction.
• What is the recommended input filter configuration for the ADC?
  A low-pass filter with a cutoff frequency of around 100kHz is recommended to reduce noise and aliasing. A simple RC filter with a 1kΩ resistor and a 10nF capacitor can be used.
• How do I optimize the ADC conversion speed and accuracy?
  To optimize ADC conversion speed and accuracy, ensure that the input signal is within the specified range, and the ADC clock frequency is set according to the datasheet. Additionally, averaging multiple conversions can improve accuracy.
• What is the recommended method for reducing EMI and RFI emissions?
  To reduce EMI and RFI emissions, use a shielded enclosure, keep signal lines short, and use a common-mode choke or ferrite bead on the power supply lines. Additionally, ensure that the PCB layout is optimized for minimal radiation.
