Application Scenarios & Design Considerations

8-/4-Channel ADCs with Simultaneous T/Hs and Reference

Alternative Part Number

  • AD7820KNZ --: 8-bit successive-approximation ADC with similar sampling rate and parallel interface, pin-compatible in many DIP-28 sockets and widely available.
  • ADC0808CCN --: 8-bit 8-channel ADC with parallel output, commonly used as a drop-in substitute for MAX155-class converters in DIP packages.
  • TLC0820ACN --: 8-bit high-speed ADC with similar conversion timing and parallel interface, suitable replacement when exact MAX155 timing is not critical.
  • AD7820KN --: 8-bit successive-approximation ADC with similar sampling rate and parallel interface, pin-compatible in many DIP-28 sockets and widely available.
