LTC1855IG#TRPBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a star topology for the power supply connections and keep the signal traces short and direct.
  • The LTC1855IG#TRPBF has an internal calibration circuit that is enabled by applying a voltage to the CAL pin. The calibration process is initiated by applying a voltage to the CAL pin and then releasing it. The device will then perform a self-calibration sequence.
  • The maximum sampling rate of the LTC1855IG#TRPBF is 400ksps. The power consumption increases with the sampling rate, so it's essential to optimize the sampling rate based on the application requirements to minimize power consumption.
  • The LTC1855IG#TRPBF outputs 16-bit digital data in a serial format. The data is transmitted in a 16-bit word, with the most significant bit (MSB) first. The output data is in a two's complement format, and the user needs to implement a serial interface to receive and process the data.
  • A 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel are recommended for power supply decoupling. Proper decoupling is essential to ensure the device's performance and accuracy. Insufficient decoupling can lead to noise and errors in the ADC conversions.
