Description
  • The ADS1115 is a precision 16-bit analog-to-digital converter (ADC) widely used in applications requiring high-resolution measurements.
  • Communicates via I²C, making it simple to interface with Arduino, Raspberry Pi, ESP32, STM32, and other microcontrollers.
  • Supports four single-ended inputs or two differential measurement pairs, enhancing flexibility for sensor interfacing.
  • Integrated Programmable Gain Amplifier (PGA) allows amplification of very small signals—ideal for low-voltage sensors, load cells, strain gauges, and thermocouples.
  • Offers configurable sampling rates up to 860 SPS, balancing accuracy and responsiveness depending on the application.
  • Operates over a wide voltage range (2.0–5.5V), enabling use in battery-powered and low-power embedded systems.
  • Compact breakout board format makes it suitable for DIY electronics, IoT devices, and laboratory measurement setups.
