MCP1259-E/UN Frequently Asked Questions (FAQ)

  • Microchip recommends following a star-grounding topology, keeping analog and digital grounds separate, and using a solid ground plane to minimize noise and EMI. Additionally, keep the input and output traces short and away from each other to reduce crosstalk.

  • To ensure accurate voltage measurement, use a high-impedance input source, keep the input voltage within the specified range, and use a low-noise, low-impedance reference voltage. Also, consider using a voltage divider or an attenuator to reduce the input voltage if it exceeds the maximum rating.

  • The maximum sampling rate of the MCP1259-E/UN depends on the clock frequency and the conversion mode. In normal mode, the maximum sampling rate is 200 ksps, while in turbo mode, it can reach up to 400 ksps. However, the actual sampling rate may be limited by the system's clock frequency and the conversion time.

  • The MCP1259-E/UN has built-in overvoltage protection up to 16V. However, if the input voltage exceeds 16V, additional external protection circuitry may be required. Consider using a voltage limiter or a clamp circuit to prevent damage to the device.

  • The MCP1259-E/UN has a built-in POR circuit that resets the device when the power supply voltage falls below a certain threshold (typically around 1.5V). The POR circuit ensures that the device starts up in a known state and prevents incorrect operation during power-up.
