The maximum sampling rate of the ADS1015 is 3300 samples per second (SPS) for a single channel, and 1500 SPS for multiple channels.
The gain settings for the ADS1015 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.
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.
To handle noise and interference in the ADS1015, use a low-pass filter on the input signals, ensure proper grounding and shielding, and consider using a ferrite bead or common-mode choke on the input lines.
The power consumption of the ADS1015 is typically 150 μA at 3.3 V and 1 MSPS, but it can vary depending on the sampling rate and other factors.
