The ADS7800 is a complete 12-bit sampling analog-todigital (A/D) converter using state-of-the-art CMOS structures. It contains a complete 12-bit successive approximation A/D converter with internal sample/hold, reference, clock, digital interface for microprocessor control, and three-state output drivers. The ADS7800 is specified at a 333kHz sampling rate. Conversion time is factory set for 2.70s max over temperature, and the high-speed sampling input stage insures a total acquisition and conversion time of 3s max over temperature. Precision, laser-trimmed scaling resistors provide industry-standard input ranges of 5V or 10V.
