ADS8512 - Texas Instruments

ADS8512 ANALOG-TO-DIGITAL CONVERTER

The ADS8512 is a complete low-power, single 5-V supply, 12-bit sampling analog-to-digital (A/D) converter. It contains a complete 12-bit capacitor-based, successive approximation register (SAR) A/D converter with sample-and-hold (S/H), clock, reference, and serial data interface. The converter can be configured for a variety of input ranges including ±10 V, .
