SPECIFICATIONS

Product Introduction:
This ADS1115 module is a high-precision, 16-bit Analog-to-Digital Converter (ADC) designed for accurate data acquisition. Its core strength lies in excellent resolution and flexible input configurations, making it an ideal choice for a wide range of measurement applications.

Features:

• High Precision & Resolution: Features true 16-bit resolution for highly accurate signal measurement, ensuring minimal error in your readings.

• Flexible Input Modes: Supports 4 single-ended inputs or 2 differential input channels with time-multiplexed sampling, providing adaptability for various sensor types and signal sources.

• Programmable Gain Amplifier (PGA): Offers six software-selectable input ranges (±256mV to ±6.144V), allowing you to measure tiny signals with high precision or larger voltages without external circuitry.

• Wide Operating Range: Powered efficiently from a single 2.0V to 5.5V supply, making it compatible with both 3.3V and 5V systems

• High-Speed I2C Interface: Communicates via a standard I2C protocol, simplifying connections to microcontrollers. It achieves a fast sampling rate of up to 860 samples per second (SPS).

• Integrated Digital Comparator: Includes a built-in comparator which can be configured to generate an alert signal when measurements exceed a predefined threshold, useful for real-time monitoring.

• High Input Impedance: Boasts a very high input impedance (3MΩ to 100MΩ), minimizing the load on the signal source being measured for greater accuracy.

• Built-in Protection: Comes with reverse polarity protection for the power supply, safeguarding the module from accidental wiring mistakes.

• Easy Prototyping: Input signals are conveniently accessible via screw terminals. The package includes complete Keil 5 source code examples for the STM32F103 platform, accelerating your development process.
