LTC1861HMS#PBF Frequently Asked Questions (FAQs)

  • The recommended layout and placement for the LTC1861HMS#PBF involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the analog signal sources. Additionally, it's recommended to use a 4-layer PCB with a dedicated analog ground plane and to keep the digital signals away from the analog signals.
  • To ensure the accuracy and stability of the ADC conversion results, it's essential to provide a clean and stable power supply, use a low-noise reference voltage, and minimize noise coupling into the analog input signals. Additionally, it's recommended to use a capacitor on the REFIN pin to filter out high-frequency noise.
  • The maximum sampling rate of the LTC1861HMS#PBF is 1.5Msps (megasamples per second). However, the actual sampling rate may be limited by the system's clock frequency, the conversion time, and the settling time of the analog input signals.
  • The sleep mode and wake-up functionality of the LTC1861HMS#PBF can be handled by asserting the SHDN pin low to enter sleep mode and de-asserting it to wake up the device. The wake-up time is typically around 5μs, and the device can be configured to wake up on a conversion complete or an external interrupt.
  • The recommended method for driving the analog input signals to the LTC1861HMS#PBF involves using a low-impedance source, such as an op-amp buffer, to drive the analog input signals. This helps to minimize the source impedance and ensure accurate ADC conversions.
