The number of pins is 16.
Here's a detailed breakdown of each pin's functionality for this 16-pin component:
Pin Number Pin Name Function Description 1 VDD Power supply pin. Connect to the positive voltage supply (typically 2.7V to 5.25V). 2 VSS Ground pin. Connect to the system ground. 3 SDA Data line for I2C interface . Used for communication between the ADC and microcontroller. 4 SCL Clock line for I2C interface. Defines the speed of data transfer between the ADC and microcontroller. 5 AIN0 Analog input channel 0. Pin for applying an analog voltage signal that will be converted into a digital value by the ADC. 6 AIN1 Analog input channel 1. Another input for an analog voltage signal. 7 AIN2 Analog input channel 2. Additional analog input. 8 AIN3 Analog input channel 3. 9 AIN4 Analog input channel 4. 10 AIN5 Analog input channel 5. 11 AIN6 Analog input channel 6. 12 AIN7 Analog input channel 7. 13 ALARM Alarm output. Active when the ADC detects an alarm condition (e.g., voltage threshold exceeded). 14 REF+ Reference voltage positive input. This defines the reference level for the analog-to-digital conversion. 15 REF- Reference voltage negative input. Completes the reference voltage circuit. 16 VOUT Output pin for digital data (typically 16-bit). This is the result of the analog-to-digital conversion. Circuit Principle: The ADS1100A0IDBVR works by converting an applied analog voltage (from AIN pins) into a corresponding digital signal. This digital signal can be read by a microcontroller or processor using the I2C communication protocol (SDA and SCL pins). The REF+ and REF- pins define the ADC's input voltage range. Alarm signals can indicate conditions such as an overvoltage or undervoltage at the analog inputs. Power supply pins, VDD and VSS, are used to power the ADC.
