8-bit A/D converters.

The ADC0803 family is a series of three CMOS 8-bit successive approximation A/D converters using a resistive ladder andcapacitive array together with an auto-zero comparator. These converters are designed to operate with microprocessor-controlledbuses 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. Additionally, the voltage reference input provides a means of encoding small analog voltages to the full 8 bits of resolution.



  • 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



  • Transducer-to-microprocessor interface
  • Digital thermometer
  • Digitally-controlled thermostat
  • Microprocessor-based monitoring and control systems
  • Maximum Supply voltage :6.5 V
  • Logic control input voltages –0.3 to +16 V
  • All other input voltages –0.3 to (VCC +0.3) V
  • Storage temperature –65 to +150 °C

Sir, could you make available any 32-bit or 16-bit audio ADC ICs?
