Overview
The ADS8507IBDWR is a 16-bit, low-power, sampling analog-to-digital converter (ADC) produced by Texas Instruments. It operates on a single 5-V analog supply and features a successive approximation register (SAR) architecture. The converter includes a sample and hold circuit, clock, reference, and data interface, making it a comprehensive solution for various analog-to-digital conversion needs. The ADS8507 is specified to operate at a 40 kHz sampling rate over an industrial temperature range of -40°C to 85°C.
