PRODUCT OVERVIEW
The ADC-HX and ADC-HZ Series are self-
Both models have identical operation except for contained, high-performance, 12-bit A/D convert- conversion speed. They can be short-cycled to give ers manufactured with thick and thin-film hybrid faster conversions in lower-resolution applica- technology. They use the successive approximation tions. Use of the internal buffer amplifier increases conversion technique to achieve a 12-bit conver- conversion time by 3 microseconds, the settling sion in 20 and 8 microseconds, respectively. Five time of the amplifier. Output coding is ple- input voltage ranges are programmable by external mentary binary, plementary offset binary, or pin connection. An internal buffer amplifier is also plementary two’s plement. Serial data is provided for applications in which 50 megohm also brought out.
