AD1938YSTZRL Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by AVDD, and then DVDD. This ensures that the internal voltage regulators are powered up in the correct order.
  • To optimize the performance of the ADCs, ensure that the analog input signals are properly filtered and buffered, and that the ADC clock frequency is set to the recommended value. Additionally, ensure that the AVDD and DVDD power supplies are well-regulated and decoupled.
  • The maximum clock frequency that can be used with the AD1938 is 192 kHz. However, the recommended clock frequency is 128 kHz to ensure optimal performance.
  • The AD1938's digital interface can be configured through the SPI port. The device can be set to master or slave mode, and the data format can be configured as I2S, DSP, or TDM.
  • The power consumption of the AD1938 depends on the operating mode and clock frequency. In typical operating conditions, the device consumes around 130 mW. However, this can be reduced to around 50 mW in low-power mode.
