ADS1115IDGSR datasheet by Texas Instruments

ADS1115IDGSR Frequently Asked Questions (FAQs)

• What is the maximum sampling rate of the ADS1115?
  The maximum sampling rate of the ADS1115 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 ADS1115?
  The gain settings on the ADS1115 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 ADS1115?
  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 ADS1115?
  To handle noise and interference on the ADS1115, 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 ADS1115?
  The power consumption of the ADS1115 is typically 360 μA at 3.3V supply voltage, and 220 μA at 2.7V supply voltage.
