描述 Description

DESCRIPTION
The ADC0803 family is a series of three CMOS 8-bit successive approximation A/D converters using a resistive ladder and capacitive array together with an auto-zero comparator. These converters are designed to operate with microprocessor-controlled buses using a minimum of external circuitry. The 3-State output data lines can be connected directly to the data bus.FEATURES
?Compatible with most microprocessors
?Differential inputs
?3-State outputs
?Logic levels TTL and MOS compatible
?Can be used with internal or external clock
?Analog input range 0 V to VCC
?Single 5 V supply
?Guaranteed specification with 1 MHz clockAPPLICATIONS
?Transducer-to-microprocessor interface
?Digital thermometer
?Digitally-controlled thermostat
?Microprocessor-based monitoring and control systems
