MAX11800ETC+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX11800ETC+?
  The recommended PCB layout for the MAX11800ETC+ is to use a 4-layer board with a solid ground plane, and to keep the analog and digital signals separate. Additionally, it's recommended to use a low-ESR capacitor for the VCC pin and to decouple the VCC pin with a 0.1uF capacitor.
• How do I optimize the performance of the MAX11800ETC+ in noisy environments?
  To optimize the performance of the MAX11800ETC+ in noisy environments, it's recommended to use a shielded cable for the analog input, to keep the analog input traces short and away from digital signals, and to use a common-mode filter or a differential amplifier to reject common-mode noise.
• What is the maximum sampling rate that can be achieved with the MAX11800ETC+?
  The maximum sampling rate that can be achieved with the MAX11800ETC+ is 1.5Msps, but this can be limited by the system's clock frequency, the analog input bandwidth, and the digital output data rate.
• How do I calibrate the MAX11800ETC+ for optimal performance?
  The MAX11800ETC+ does not require calibration, as it has an internal calibration circuit that sets the gain and offset of the ADC. However, it's recommended to perform a system-level calibration to account for any external component tolerances and PCB layout variations.
• What is the power consumption of the MAX11800ETC+?
  The power consumption of the MAX11800ETC+ depends on the operating mode and the clock frequency. In normal operation, the power consumption is typically around 15mW, but it can be reduced to around 1mW in shutdown mode.
