Overview
The ADS8507IBDW is a 16-bit, low-power, sampling analog-to-digital converter (ADC) produced by Texas Instruments. This device operates on a single 5-V analog supply and features a successive approximation register (SAR) architecture. It includes a complete ADC with sample and hold, clock, reference, and data interface. The converter supports various input ranges, including ±10 V, 4 V, and 5 V, and is designed for high accuracy and low power consumption. The ADS8507IBDW is packaged in a 28-pin SOIC (DW) package and is specified to operate over an industrial temperature range of -40°C to 85°C.
