ADS1234IPW Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the ADS1234IPW?
  The ADS1234IPW requires careful layout and placement to minimize noise and ensure accurate conversions. TI recommends placing the device close to the analog signal source, using a solid ground plane, and keeping the analog and digital traces separate. Additionally, decoupling capacitors should be placed close to the device's power pins.
• How do I optimize the ADC's performance for my specific application?
  To optimize the ADS1234IPW's performance, consider the following: choose the correct gain setting, adjust the sampling rate, and select the appropriate input range. Additionally, ensure proper filtering and shielding to minimize noise and electromagnetic interference (EMI).
• What is the recommended power-up sequence for the ADS1234IPW?
  To ensure proper operation, power up the ADS1234IPW in the following sequence: VDD, AVDD, and then DVDD. This sequence helps prevent latch-up and ensures the device's internal voltage regulators function correctly.
• How do I handle the ADS1234IPW's digital output data?
  The ADS1234IPW outputs 24-bit data in a binary two's complement format. To handle the output data, ensure your microcontroller or processor can handle 24-bit data and perform any necessary data formatting or scaling for your application.
• What is the ADS1234IPW's latency and how does it affect my application?
  The ADS1234IPW has a latency of approximately 12 clock cycles. This latency may affect real-time applications or those requiring fast conversion rates. Consider this latency when designing your system and ensure it meets your application's timing requirements.
