DESCRIPTION
●The ADS8513 is a complete low-power, single 5-V supply, 16-bit sampling analog-to-digital (A/D)
●converter. It contains a complete 16-bit capacitor-based, successive approximation register (SAR) A/D converter with sample and hold, clock, reference, and serial data interface. The converter
●can be configured for a variety of input ranges including ±10 V, ±5 V, 0 V to 10 V, and 0.5 V to
●4.5 V. A high-impedance, 0.3-V to 2.8-V input is also available with input impedance greater than 10 MΩ. For most input ranges, the input voltage can swing to 25 V or –25 V without damage to the converter.
