AI Summary

AD673JNZ by Analog Devices: 8 Bit Analog to Digital Converter 1 Input 1 SAR 20-PDIP.

This high-speed 8-bit flash ADC is housed in a 20-PDIP package and offers a much faster conversion speed. It operates on a single +5V rail, making it a viable functional alternative, though it requires a board redesign and potential software adjustments.

  • Very fast conversion time (under 1.5 us) compared to the original 20 us
  • Available as legacy stock from specialized distributors (e.g., Rochester)
  • Single +5V power supply simplifies system power design
  • Requires complete PCB redesign due to incompatible pin configuration
  • Requires an external voltage reference

This is a classic industry-standard 8-bit successive approximation ADC in a 20-PDIP package. It operates on a single +5V rail, simplifying power design, but requires a complete circuit board layout redesign and input scaling because of different pinout configurations and input voltage ranges.

  • Highly popular and widely available 8-bit parallel ADC
  • Single +5V supply operation simplifies power rail design
  • Low cost and multi-sourced industry standard
  • Requires complete PCB redesign due to different pin configuration
  • Different input voltage range (0 to 5V) requiring external signal conditioning

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
