MCP47CVB28-20E/ST Frequently Asked Questions (FAQs)

  • Microchip recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. Additionally, it's recommended to use a low-ESR capacitor for the output filter and to keep the input and output traces as short as possible.
  • To ensure stability, make sure to follow the recommended output capacitor values and ESR ranges, and to keep the output voltage within the specified range. Additionally, it's recommended to add a small ceramic capacitor (e.g. 10nF) between the VOUT pin and GND to improve stability.
  • The maximum output current of the MCP47CVB28-20E/ST is 20mA. However, it's recommended to derate the output current based on the ambient temperature and the output voltage to ensure reliable operation.
  • The MCP47CVB28-20E/ST can be programmed using a 3-wire serial interface (SPI). The output voltage is set by writing a 7-bit code to the DAC register. The voltage output is calculated using the formula: VOUT = (VREF x CODE) / 128, where VREF is the reference voltage (2.5V for the MCP47CVB28-20E/ST).
  • The MCP47CVB28-20E/ST has a power-on reset (POR) circuit that ensures the output voltage is at a safe state during power-up. The output voltage is held low during POR, and then ramps up to the programmed value once the device is fully powered up.
