Microprocessor-Compatible ANALOG-TO-DIGITAL CONVERTER
FEATURES
q COMPLETE 12-BIT A/D CONVERTER WITH REFERENCE, CLOCK, AND 8-, 12-, or 16BIT MICROPROCESSOR BUS INTERFACE q ALTERNATE SOURCE FOR HI774 A/D CONVERTER: 8.5µs Conversion Time, 150ns Bus Access Time q FULLY SPECIFIED FOR OPERATION ON ±12V OR ±15V SUPPLIES q NO MISSING CODES OVER TEMPERATURE: 0°C to +75°C: ADC774J, K –55°C to +125°C: ADC774SH, TH formance. It is complete with a self-contained +10V reference, internal clock, digital interface for microprocessor control, and three-state outputs. The reference circuit, containing a buried zener, is lasertrimmed for minimum temperature coefficient. The clock oscillator is current-controlled for excellent stability over temperature.
