The ADS8517 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 data interface. The converter can be configured for a variety of input ranges including ±10 V, 4 V, and 5 V. For most input ranges, the input voltage can swing to 25 V or –25 V without damage to the device.

An SPI-compatible serial interface allows data to be synchronized to an internal or external clock. A full parallel interface using the selectable BYTE pin is also provided to allow the maximum system design flexibility. The ADS8517 is specified at a 200-kHz sampling rate over the industrial -40°C to +85°C temperature range.
