Features: ADS1115 16-bit, 4-channel analog-to-digital converter delivers precise analog measurement with a programmable gain amplifier for improved sensitivity in microprocessor-based projects. Suitable for 2.0V–5.5V supply voltage, this I²C module features low current consumption (150 µA), a sampling rate of up to 860 samples per second, and configurable single-ended or differential inputs for flexible sensor integration. Ideal for electronics engineers and developers requiring multi-channel data acquisition in industrial automation, environmental monitoring, or instrumentation applications. Monitor sensor arrays, audio signals, or biomedical signals with 16-bit resolution. The I²C interface supports expansion up to four boards (16 total channels) on the same bus. Integrated programmable comparator and auto-shutdown mode enhance energy efficiency in battery-powered applications while maintaining 16-bit accuracy for critical measurements. Specifications: Resolution: 16 bits Channels: 4 single-ended (AN0–AN3) or 2 differential inputs Input voltage range: 2.0–5.5V Supply current (continuous mode): 150 µA Dimensions: Approx. 38 × 18 × 3 mm (1.48 × 0.7 × 0.12 in) Package Includes: Option 1: 1 × ADS1115 Analog-to-Digital Converter board Option 2: 2 × ADS1115 Analog-to-Digital Converter boards Note: 1. Slight dimensional variations (±1–2 cm) may occur due to manual measurement. 2. Screen settings may cause slight color or brightness differences between the image and the actual product.
