Low-Power, Serial 12-Bit Sampling Analog-To-Digital Converter

The ADS7812 is a low-power, single +5V supply, 12-bit sampling Analog-to-digital converter. It contains a complete 12-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 10V, 5V, 0V to 10V, and 0.5V to 4.5V. A high impedance 0.3V to 2.8V input range is also available (input impedance > 10M). 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 The ADS7812 is specified at a 40kHz sampling rate over the ?40C to +85C temperature range. It is available in a 0.3" DIP-16 or an SO-16 package.
