Package and Pin Function Specifications:
The ADS1115IDGSR comes in a SOIC-8 package, which means it has 8 pins in total. Below is the detailed breakdown of the function for each of these pins.
Pin Function and Description (SOIC-8 Package) Pin Number Pin Name Function Description 1 VDD Power supply pin. This is where the positive voltage for the device is supplied (typically 2.0V to 5.5V). 2 SCL I2C Clock (Serial Clock) pin. This pin is used to provide the clock signal for communication via the I2C bus. 3 SDA I2C Data (Serial Data) pin. This is the data line for I2C communication, used to transfer data to and from the device. 4 ADDR Address selection pin. This pin is used to set the I2C address of the device. It can be connected to ground or VDD to select the address. 5 ALERT/RDY Alert/Ready pin. This is an output pin that indicates when a conversion is complete or when an alert condition is triggered. 6 GND Ground pin. This is the return path for the power supply. 7 A0 Analog input pin. This is one of the analog input pins (A0 to A3), which accepts analog signals to be converted to digital form. 8 A1 Analog input pin. This is another analog input pin for accepting input signals.Package Details:
