HI-574A, HI-674A Data Sheet August 7, 2008 FN3096.6 Complete, 12-Bit A/D Converters with Features Microprocessor Interface Complete 12-Bit A/D Converter with Reference and Clock The HI-X74(A) is a complete 12-bit, Analog-to-Digital Full 8-Bit, 12-Bit or 16-Bit Microprocessor Bus Interface Converter, including a +10V reference clock, three-state Bus Access Time . 150ns outputs and a digital interface for microprocessor control. Successive approximation conversion is performed by two No Missing Codes Over Temperature monolithic dice housed in a 28 lead package. The bipolar Minimal Setup Time for Control Signals analog die features the Intersil Dielectric Isolation process, which provides enhanced AC performance and freedom Fast Conversion Times from latch-up. - HI-574A (Max) 25s - HI-674A (Max) 15s Custom design of each IC (bipolar analog and CMOS digital) Low Noise, via Current-Mode Signal Transmission has yielded improved performance over existing versions of Between Chips this converter. The voltage comparator features high PSRR plus a high speed current-mode latch, and provides precise Byte Enable/Short Cycle (A Input) O decisions down to 0.1 LSB of input overdrive. More than 2X - Guaranteed Break-Before-Make Action, Eliminating Bus reduction in noise has been achieved by using current Contention During Read Operation. Latched by Start instead of voltage for transmission of all signals between the Convert Input (To Set the Conversion Length) analog and digital ICs. Also, the clock oscillator is current Supply Voltage 12V to 15V controlled for excellent stability over temperature. Pb-Free Available (RoHS Compliant) The HI-X74(A) offers standard unipolar and bipolar input ranges, laser trimmed for specified linearity, gain and offset Applications accuracy. The low noise buried zener reference circuit is Military and Industrial Data Acquisition Systems trimmed for minimum temperature coefficient. Electronic Test and Scientific Instrumentation Power requirements are +5V and 12V to 15V, with typical dissipation of 385mW (HI-574A, HI-674A) at 12V.
