ADS8344E/2K5 datasheet by Texas Instruments

ADS8344E/2K5 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the ADS8344E/2K5?
  The recommended power-up 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 ADS8344E/2K5 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 ADS8344E/2K5.
• What is the maximum sampling rate that can be achieved with the ADS8344E/2K5?
  The maximum sampling rate of the ADS8344E/2K5 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 ADS8344E/2K5, and what is the format of the output data?
  The ADS8344E/2K5 outputs 16-bit parallel data. The output data is in two's complement format, with the most significant bit (MSB) first. The output data can be handled using a microcontroller or FPGA, and can be processed and stored for further analysis.
• What is the typical power consumption of the ADS8344E/2K5, and how can I reduce power consumption?
  The typical power consumption of the ADS8344E/2K5 is 15mW at 3V and 100kSPS. To reduce power consumption, consider using a lower clock frequency, reducing the sampling rate, or using the device's power-down mode when not in use.
