ADS1114IDGSR – TEXAS INSTRUMENTS

The Texas Instruments ADS1114IDGSR is a low-power, 16-bit, single-channel analog-to-digital converter (ADC) housed in a small, space-saving 10-pin WSON package. Operating from a 2.0V to 5.5V supply voltage, it offers a ±0.25% typical integral nonlinearity and a maximum input voltage range that tracks the supply voltage (Vref). The ADS1114IDGSR utilizes a successive approximation architecture, achieving a conversion rate up to 80 SPS (samples per second). Data is output via a 3-wire SPI interface, simplifying integration into microcontroller systems. Its low power consumption (typically 150µA at 5V) makes it suitable for battery-powered applications._x000D_

Common use cases include precision data acquisition in portable medical devices, industrial sensors, and low-power monitoring systems. The ADS1114IDGSR’s advantages stem from its combination of high resolution, low power, and compact footprint. Its high accuracy and low noise performance are critical in applications demanding precise analog signal conversion. However, its relatively low sampling rate limits its applicability in high-speed data acquisition scenarios. Designers should consider this trade-off between resolution, power consumption, and speed when selecting the ADS1114IDGSR for a specific application.
