ADS112U04IRTER Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the ADC close to the analog signal sources. Additionally, use short and shielded traces, and avoid running digital signals near the analog signals.
  • Use a buffer amplifier or an op-amp with a low output impedance to drive the analog input pins. This will help to reduce the input impedance and ensure accurate readings.
  • The maximum sampling rate of the ADS112U04IRTER is 2 MSPS (mega-samples per second). However, this rate may be limited by the system's clock frequency, analog input bandwidth, and digital interface.
  • Perform a system-level calibration by applying a known input voltage and adjusting the ADC's offset and gain registers to match the expected output code. Additionally, consider using an external reference voltage and temperature compensation to further improve accuracy.
  • The power consumption of the ADS112U04IRTER is typically around 1.5 mA at 3.3 V supply voltage. To reduce power consumption, consider using the ADC's power-down mode, reducing the clock frequency, or using a lower supply voltage.
