概述
Description
The ADS1115IDGST is a 16-bit, precision analog-to-digital converter (ADC) from Texas Instruments. It features four single-ended or two differential input channels, a programmable gain amplifier (PGA), and an I²C interface for easy communication with microcontrollers.
Key features:
- Resolution: 16 bits (higher accuracy than 10- or 12-bit ADCs).
- Input Range: Adjustable via PGA (±6.144V to ±0.256V).
- Sampling Rate: Up to 860 samples per second (SPS).
- Low Power: Suitable for battery-powered applications.
- Comparator: Built-in for threshold detection.
Common uses include sensor monitoring (temperature, pressure, strain gauges), portable instrumentation, and industrial systems. Its small VSSOP-10 package makes it ideal for space-constrained designs.
For interfacing, libraries like Adafruit_ADS1X15 (Arduino) or smbus2 (Python/RPi) simplify integration.
Summary: A versatile, high-precision ADC for low-voltage analog signal measurement with I²C control.
