ADC0803 - CMOS 8-bit A/D converters

General 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.

Key Features

  • VREF/2 9 D GND 10.
  • 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 SL00016 Figure 1. Pin configuration.

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. The differential analog voltage input allows for increased common-mode rejection and provides a means to adjust the zero-scale offset.
