ADS1118IDGST datasheet by Texas Instruments

ADS1118IDGST Frequently Asked Questions (FAQs)

• What is the maximum sampling rate of the ADS1118?
  The maximum sampling rate of the ADS1118 is 860 samples per second (SPS) for a single channel, and 240 SPS for multiple channels.
• How do I configure the gain settings on the ADS1118?
  The gain settings on the ADS1118 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 ADS1118?
  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.
• How do I handle the noise and interference on the ADS1118?
  To handle noise and interference on the ADS1118, use a low-pass filter on the analog input, use a shielded cable, and keep the analog input traces away from digital traces on the PCB.
• What is the power consumption of the ADS1118?
  The power consumption of the ADS1118 is typically 350 μA at 3.3V supply voltage, but it can vary depending on the sampling rate and other operating conditions.
