NOT RECOMMENDED FOR NEW DESIGNS POSSIBLE SUBSTITUTE PRODUCT ISL263XX AND ISL267XX FAMILIES www.intersil.com/converters/ products DATASHEET HI-574A, HI-674A FN3096 Rev 6.00 Complete, 12-Bit A/D Converters with Microprocessor Interface Aug 7, 2008 The HI-X74(A) is a complete 12-bit, Analog-to-Digital Features Converter, including a +10V reference clock, three-state Complete 12-Bit A/D Converter with Reference and Clock outputs and a digital interface for microprocessor control. Successive approximation conversion is performed by two Full 8-Bit, 12-Bit or 16-Bit Microprocessor Bus Interface monolithic dice housed in a 28 lead package. The bipolar Bus Access Time . 150ns analog die features the Intersil Dielectric Isolation process, No Missing Codes Over Temperature which provides enhanced AC performance and freedom from latch-up. Minimal Setup Time for Control Signals Custom design of each IC (bipolar analog and CMOS digital) Fast Conversion Times has yielded improved performance over existing versions of - HI-574A (Max) 25s this converter. The voltage comparator features high PSRR - HI-674A (Max) 15s plus a high speed current-mode latch, and provides precise Low Noise, via Current-Mode Signal Transmission decisions down to 0.1 LSB of input overdrive. More than 2X Between Chips reduction in noise has been achieved by using current Byte Enable/Short Cycle (A Input) instead of voltage for transmission of all signals between the O - Guaranteed Break-Before-Make Action, Eliminating Bus analog and digital ICs. Also, the clock oscillator is current Contention During Read Operation. Latched by Start controlled for excellent stability over temperature. Convert Input (To Set the Conversion Length) The HI-X74(A) offers standard unipolar and bipolar input Supply Voltage 12V to 15V ranges, laser trimmed for specified linearity, gain and offset accuracy. The low noise buried zener reference circuit is Pb-Free Available (RoHS Compliant) trimmed for minimum temperature coefficient. Applications Power requirements are +5V and 12V to 15V, with typical Military and Industrial Data Acquisition Systems dissipation of 385mW (HI-574A, HI-674A) at 12V.
