Pinout
The ADS1112IDGSR is available in an 8-pin VSSOP (DGSR) package. The pin functions are as follows:
1. VDD: Power supply voltage input.
2. GND: Ground reference point for the device.
3. SCL: Serial clock input for I2C communication.
4. SDA: Serial data line for I2C communication (data input/output).
5. ADDR: Sets the I2C address configuration.
6. A0: Differential input positive terminal (analog input).
7. A1: Differential input negative terminal or another analog input for single-ended measurements.
8. DRDY: Data ready output (open-drain), indicates when conversion data is available.
The ADS1112 interfaces with microcontrollers through the I2C protocol, providing easy integration into digital systems for precise analog-to-digital conversion tasks.
