ADS8344N datasheet by Texas Instruments

ADS8344N Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the ADS8344N?
  The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input signal. This ensures proper operation and prevents damage to the device.
• How do I optimize the layout for the ADS8344N to minimize noise and ensure accurate conversions?
  To minimize noise and ensure accurate conversions, keep the analog input traces short and away from digital traces. Use a solid ground plane and decouple the power supplies with 0.1uF and 10uF capacitors. Also, ensure that the analog input signal is properly filtered and buffered before connecting it to the ADS8344N.
• What is the maximum sampling rate I can achieve with the ADS8344N?
  The maximum sampling rate of the ADS8344N is 100kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input signal bandwidth, and other system-level factors.
• How do I handle the output data from the ADS8344N? Is it in binary or two's complement format?
  The ADS8344N outputs data in binary format. The most significant bit (MSB) is the sign bit, and the remaining bits represent the magnitude of the converted value. The output data is not in two's complement format.
• Can I use the ADS8344N in a multiplexed configuration, and if so, how?
  Yes, the ADS8344N can be used in a multiplexed configuration. To do this, connect multiple analog input signals to the device through an analog multiplexer. Then, use the chip select (CS) pin to select the desired input channel. Ensure that the multiplexer is properly synchronized with the ADS8344N's conversion cycle.
