ADS1115IRUGR datasheet by Texas Instruments

ADS1115IRUGR 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 by writing to the Config Register (Register 0x01). The gain settings are set using bits 7-5 of the Config Register, with options for 2/3, 1, 2, 4, 8, or 16 times gain.
• 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.
• Can I use the ADS1115 with a 5V microcontroller?
  The ADS1115 is a 3.3V device, but it is 5V tolerant on its digital inputs. However, it's recommended to use a level shifter or voltage divider to ensure the voltage levels are compatible.
• How do I calibrate the ADS1115?
  The ADS1115 does not require calibration. It has an internal voltage reference and oscillator, and the gain and offset are trimmed during manufacturing. However, you may need to calibrate your system as a whole depending on your specific application.
