Overview
The ADS8509IBDBR from Texas Instruments is a high-performance, 16-bit analog-to-digital converter (ADC) designed for precision data acquisition and signal processing. This successive approximation register (SAR) ADC features a complete sampling-and-hold circuit, enabling accurate sampling of input signals up to its maximum sampling rate of 250 kilosamples per second (kSPS). The device operates from a single 5-V supply, ensuring low power consumption, and is fully specified over the industrial temperature range of -40°C to 85°C.
