The ADS7813P is a low-power sampling Analog-to-digital Converter (ADC) contains a complete 16-bit capacitor-based SAR A/D with a sample/hold, clock, reference and serial data interface. The converter can be configured for a variety of input ranges including ±10/±5V, 0 to 10V and 0.5 to 4.5V. A high impedance 0.3V to 2.8V input range is also available. For most input ranges, the input voltage can swing to +16.5V or -16.5V without damage to the converter. A flexible SPI compatible serial interface allows data to be synchronized to an internal or external clock.
