LTC2498HUHF#PBF Frequently Asked Questions (FAQs)

  • A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the sensitive analog signals away from the digital signals. Also, use a low-ESR capacitor for the VCC pin and a 0.1uF capacitor for the REF pin.
  • Calibration involves adjusting the internal offset and gain of the ADC. The datasheet provides a calibration procedure that involves applying a known input voltage and adjusting the offset and gain registers to achieve the desired accuracy.
  • The maximum sampling rate of the LTC2498HUHF#PBF is 15ksps. The power consumption increases with the sampling rate, so it's essential to balance the sampling rate with power consumption requirements.
  • The LTC2498HUHF#PBF has built-in overvoltage and undervoltage protection. It can withstand input voltages up to 7V without damage, and it has a brownout detector that resets the device if the supply voltage falls below 2.7V.
  • The recommended power-up sequence is to apply the analog supply voltage (VCC) first, followed by the digital supply voltage (DVCC), and then the clock signal. This ensures that the analog circuitry is powered up before the digital circuitry.
