Description

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, ±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.

An SPI-compatible serial interface allows data to be synchronized to an internal or external clock. The ADS8512 is specified at 40-kHz sampling rate over the -40°C to +85°C industrial temperature range.
