ADS1112IDRCR datasheet by Texas Instruments

ADS1112IDRCR Frequently Asked Questions (FAQs)

• What is the maximum sampling rate of ADS1112IDRCR?
  The maximum sampling rate of ADS1112IDRCR is 860 samples per second (SPS) in single-shot mode and 128 SPS in continuous conversion mode.
• How do I configure the gain settings for the ADS1112IDRCR?
  The gain settings for the ADS1112IDRCR can be configured using the PGA (Programmable Gain Amplifier) bits in the Config Register. The gain can be set to 2/3, 1, 2, 4, 8, or 16.
• What is the purpose of the DRDY pin on the ADS1112IDRCR?
  The DRDY (Data Ready) pin is an output pin that goes low when a conversion is complete and the data is ready to be read. It can be used to interrupt the microcontroller to read the data.
• Can I use the ADS1112IDRCR with a 5V microcontroller?
  Yes, the ADS1112IDRCR is compatible with 5V microcontrollers. The digital interface is 5V tolerant, but the analog input voltage range is limited to 0V to VDD (which is typically 3.3V or 2.7V).
• How do I handle the noise and interference in the ADS1112IDRCR measurements?
  To handle noise and interference, use proper PCB layout techniques, such as separating analog and digital grounds, using a ground plane, and shielding the device. Additionally, use the built-in 50/60 Hz rejection filter and consider using external filters or averaging techniques.
