The ADC0804 are CMOS 8-bit successive approximation A/D converters that use a differential potentiometric ladder—similar to the 256R products. These converters are designed to allow operation with the NSC800 and INS8080A derivative control bus with TRI-STATE output latches directly driving the data bus. These A/Ds appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed. Differential analog voltage inputs allow increasing the common-mode rejection and offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow ncoding any smaller analog voltage span to the full 8 bits of resolution.


  • Compatible with any microcontroller access time – 135 ns.
  • Easy interface to all microprocessors, or operates “stand alone”.
  • Differential analog voltage inputs.
  • Logic inputs and outputs meet both MOS and TTL voltage level specifications.
  • On-chip clock generator.
  • 0V to 5V analog input voltage range with single 5V supply.
  • No zero adjust required.
  • 0.3″ standard width 20-pin DIP package.
  • Operates ratiometrically or with 5 VDC, 2.5 VDC, or analog span adjusted voltage reference.
