The maximum sampling rate of the ADS1110 is 860 samples per second (SPS) for a single channel, and 430 SPS for multiple channels.
The gain settings on the ADS1110 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 on the ADS1110, use a low-pass filter on the analog input, ensure proper grounding and shielding, and consider using a ferrite bead or common-mode choke to filter out high-frequency noise.
The power consumption of the ADS1110 is typically 350 μA at 3.3V supply voltage, but it can vary depending on the sampling rate and other operating conditions.
