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
