Description:
The ADS1115 is a high-precision 16-bit Analog-to-Digital Converter (ADC) module with an I2C interface. It is designed to measure analog signals with high accuracy and is commonly used with microcontrollers like Arduino, ESP32, and Raspberry Pi for sensor data acquisition.
Specifications:
Type: 16-bit ADC (Analog to Digital Converter)
Resolution: 16-bit
Channels: 4 (single-ended) / 2 (differential)
Interface: I2C
Programmable Gain Amplifier (PGA): ±256mV to ±6.144V
Supply Voltage: 2.0V to 5.5V
Data Rate: Up to 860 samples per second
Address Options: 0x48 to 0x4B (configurable)
Package: Module / Breakout Board
Mounting: Through-hole / Header pins
The ADS1115 provides high-resolution analog measurements with low noise and flexible input configuration
Features:
High resolution (16-bit)
Built-in programmable gain amplifier
Multiple input channels
I2C communication (saves pins)
Low power consumption
Wide voltage compatibility
Applications:
Sensor interfacing
Data acquisition systems
Voltage monitoring
Battery measurement
Industrial and IoT projects
Pin Identification:
VCC → Power supply
GND → Ground
SCL → I2C Clock
SDA → I2C Data
ADDR → Address select
ALERT/RDY → Interrupt output
Important Note:
Not a DAC (only analog input, no analog output)
Ensure correct I2C address configuration
Use pull-up resistors for I2C lines if required
Input voltage must not exceed VDD range
Package Includes:
1 × ADS1115 ADC Module
