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 clock

APPLICATIONS

? Transducer-to-microprocessor interface

? Digital thermometer

? Digitally-controlled thermostat

? Microprocessor-based monitoring and control systems
