Overview
The ADS8513IBDWR is a highly versatile and efficient 16-bit analog-to-digital converter (ADC) designed by Texas Instruments. This low-power ADC operates on a single 5V supply and features a capacitor-based, successive approximation register (SAR) architecture. It includes a sample and hold circuit, clock, reference, and a serial data interface. The converter is configurable for various input ranges, including ±10V, ±5V, 0V to 10V, 0.5V to 4.5V, and a high-impedance range from 0.3V to 2.8V, making it suitable for a wide range of applications.
