ADC574AJH中文资料Microprocessor-Compatible ANALOG-TO-DIGITAL CONVERTER数据手册TI规格书

描述 Description

DESCRIPTION
The ADC574A is a 12-bit successive approximation analog-to-digital converter, utilizing state-of-the- art CMOS and laser-trimmed bipolar die custom-designedfor freedom from latch-up and for optimum AC per 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 laser trimmed for minimum temperature coefficient. The clock oscillator is current-controlled for excellent stability over temperature. Full-scale and offset errors maybe externally trimmed to zero. Internal scaling resistors are provided for the selection of analog input signal ranges of 0V to +10V, 0V to +20V, ±5V, and ±10V.FEATURES
●COMPLETE 12-BIT A/D CONVERTER WITH REFERENCE, CLOCK, AND 8-, 12-, or 16- BIT MICROPROCESSOR BUS INTERFACE
●IMPROVED PERFORMANCE SECOND SOURCE FOR 574A-TYPE A/D CONVERTERS
    Conversion Time: 25µs max
    Bus Access Time: 150ns max
    AOInput: Bus Contention During Read
    Operation Eliminated
●DUAL IN-LINE PLASTIC, PLCC AND HERMETIC CERAMIC
●FULLY SPECIFIED FOR OPERATION ON ±12V OR ±15V SUPPLIES
●NO MISSING CODES OVER TEMPERATURE: 0°C to +75°C: ADC574AJ and K Grades –55°C to +125°C: ADC574ASH, TH
