Details

The ADS1115 is a 16-bit, 860-SPS, 4-channel delta-sigma ADC featuring a programmable gain amplifier (PGA), internal voltage reference, and oscillator. It communicates via the I2C protocol and is designed for high-precision analog measurements in a compact form factor. This component is perfect for reading data from sensors such as thermocouples, strain gauges, and pressure sensors where high resolution is required. Its ultra-small X2QFN-10 package makes it suitable for space-constrained applications. The ADS1115 operates from a low power consumption of just 150µA, making it ideal for battery-powered devices. It supports a wide input voltage range and can be configured for single-ended or differential measurements. Choose the ADS1115 for reliable, high-precision analog-to-digital conversion in your IoT, robotics, or instrumentation projects.
