LTC2358CLX-18#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 analog and digital signals separate. Additionally, use a low-ESR capacitor for the VCC pin and a 0.1uF capacitor for the REF pin. Refer to the application note AN115 for more details.
  • Calibration involves adjusting the offset and gain of the ADC. Use the CAL pin to adjust the offset and the FSC pin to adjust the gain. Refer to the datasheet section on calibration for more details. It's also recommended to use a high-accuracy voltage reference and a stable clock source.
  • The maximum sampling rate of the LTC2358CLX-18#PBF is 1.5Msps. The power consumption increases with the sampling rate, so it's recommended to use the lowest sampling rate necessary for the application to minimize power consumption.
  • The digital output data from the LTC2358CLX-18#PBF is in a 16-bit twos-complement format. The output data is available on the D[15:0] pins. The data is output in a serial format, with the most significant bit (MSB) first. The output data can be read using a microcontroller or an FPGA.
  • The recommended power-up sequence is to power up the VCC pin first, followed by the AVCC pin, and then the digital power pins. This sequence ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent latch-up and ensures proper device operation.
