MC1121DMR2 Frequently Asked Questions (FAQ)

  • A good PCB layout is crucial for the MC1121DMR2. Ensure a solid ground plane, keep the input and output traces short and symmetrical, and use a common mode choke to reduce EMI. Refer to onsemi's application note AND8033/D for a recommended layout.

  • Choose X7R or X5R ceramic capacitors with a voltage rating of at least 2.5 times the input voltage. For the input capacitor, a value between 1uF to 10uF is recommended. For the output capacitor, a value between 10uF to 22uF is recommended. Ensure the capacitors are placed close to the device.

  • The MC1121DMR2 can operate from -40°C to 125°C. However, the device's performance may degrade at higher temperatures. Ensure proper thermal management and consider derating the device's performance at high temperatures.

  • The MC1121DMR2 requires a bias voltage between 2.5V to 5.5V. Ensure the bias voltage is stable and noise-free. Use a voltage regulator or a low-dropout regulator to generate the bias voltage. Avoid using a resistive divider network as it can introduce noise and affect the device's performance.

  • The MC1121DMR2 can operate with input voltages between 2.5V to 5.5V. However, the device's performance is optimized for input voltages between 3.3V to 4.5V. Ensure the input voltage is within the recommended range for optimal performance.
