Description
The ADS1114IDGSR is a 16-bit, precision analog-to-digital converter (ADC) from Texas Instruments. It features a low-power, I²C-compatible interface and operates from 2.0V to 5.5V, making it suitable for battery-powered applications.
Key features:
- 16-bit resolution with programmable gain (PGA) for small signal amplification.
- Four single-ended or two differential input channels.
- Continuous or single-shot conversion modes (up to 860 samples/second).
- Internal oscillator, comparator, and voltage reference for simplified design.
- Tiny MSOP-10 (DGS) package, ideal for space-constrained applications.
Common uses include sensor monitoring (temperature, pressure, strain gauges), portable instrumentation, and industrial control systems. Its high accuracy, low power (150µA active, 0.5µA shutdown), and small footprint make it a versatile choice for precision measurement.
For detailed specs, refer to the [TI datasheet](https://www.ti.com/product/ADS1114).
