Overview
The ADS1115IDGST is a 16-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS111x family and is designed for high-performance measurement of analog signals. It features four input channels, a programmable gain amplifier (PGA), an internal oscillator, and a voltage reference, making it highly versatile for various applications. The ADS1115IDGST operates over an I2C interface and supports both continuous conversion and single-shot modes, which helps in reducing power consumption during idle periods. With a low power consumption of 150 µA, it is ideal for battery-powered devices and compact designs due to its small 10-pin VSSOP package.
