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
