MCP4902T-E/SL Frequently Asked Questions (FAQs)

  • The output impedance of the MCP4902T-E/SL is approximately 10 ohms. This is not explicitly stated in the datasheet, but it can be calculated based on the output current capability and the voltage swings specified in the datasheet.
  • To ensure monotonicity when using the MCP4902T-E/SL, it is recommended to use a buffer or an op-amp to drive the output of the DAC. This helps to reduce the output impedance and ensures that the output voltage changes monotonically with the input code.
  • Yes, the MCP4902T-E/SL can be used in a multiple-master SPI bus environment. The DAC has a three-state output buffer that allows multiple masters to share the same bus. However, the user must ensure that the masters do not assert the CS (Chip Select) pin simultaneously, as this can result in bus contention.
  • The settling time of the MCP4902T-E/SL is not explicitly stated in the datasheet. However, based on the output slew rate and the output voltage swing, the settling time can be estimated to be around 1-2 us.
  • No, the MCP4902T-E/SL is not suitable for driving a transformer. The DAC is designed to drive resistive loads and the output current is limited to 20 mA. Driving a transformer requires a high-current output stage, which is not available on the MCP4902T-E/SL.
