The maximum sampling rate of the ADS1110 is 860 samples per second (SPS) for the 16-bit mode and 2,000 SPS for the 12-bit mode.
The gain settings on the ADS1110 can be configured using the PGA (Programmable Gain Amplifier) bits in the Config Register. The PGA bits allow you to set the gain to 2/3, 1, 2, 4, 8, or 16.
The DRDY (Data Ready) pin is an output pin that goes low when a new conversion result is available in the data register. It can be used to interrupt the microcontroller to read the conversion result.
To handle noise and interference on the ADS1110, use a proper PCB layout, add decoupling capacitors, and use a low-pass filter on the analog input pins. Additionally, consider using a shielded cable and a ground plane to reduce electromagnetic interference.
The power consumption of the ADS1110 varies depending on the operating mode. In normal operation, the typical current consumption is 150 μA. In power-down mode, the typical current consumption is 5 μA.
