ADS1284IRHFT Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Also, use short and direct traces for the analog inputs and outputs, and avoid crossing digital signals over analog signals.
  • Use a low-pass filter at the input, and consider using a shielded enclosure to reduce electromagnetic interference (EMI). Also, use a decoupling capacitor (e.g., 10uF) between VCC and GND, and a ferrite bead or a common-mode choke to filter out high-frequency noise.
  • The ADS1284IRHFT can achieve a maximum sampling rate of 400 kSPS (kilosamples per second) in single-channel mode, and 200 kSPS in dual-channel mode.
  • Perform a system calibration by applying a known input voltage and adjusting the offset and gain registers to achieve the desired output code. Also, consider using an external voltage reference (e.g., TLV431) for improved accuracy.
  • The ADS1284IRHFT has a typical power consumption of 12.5 mW at 3.3V and 400 kSPS, and 7.5 mW at 2.7V and 200 kSPS. However, this can vary depending on the specific application and operating conditions.
