Description
The ADS1114IDGST from Texas Instruments is a high-precision, 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) designed for demanding sensor measurement applications. This single-channel converter offers a programmable data rate ranging from 8 samples per second (SPS) up to 860 SPS, allowing engineers to balance resolution and speed based on project requirements. Its sophisticated architecture includes an integrated Programmable Gain Amplifier (PGA), a low-drift voltage reference, and a digital comparator, all packed into a compact 10-pin VSSOP package.
Optimized for efficiency, the ADS1114 consumes a minimal 150µA in continuous conversion mode, making it an excellent choice for power-sensitive and space-constrained designs. Whether operating in continuous conversion or single-shot mode, the I²C interface ensures easy integration with microcontrollers, providing reliable digital data conversion for a wide range of industrial and consumer electronics.
