It appears this chip is no longer available.

According to who? Allegro still says it's an active line item.

Remember that current global conditions mean that many parts are in incredibly short supply and have extreme lead times. Many suppliers may simply be unable to get stock until 2022.

Use Octopart or Findchips to find distributors. There are parts available. Even the SOIC chips (ES) are available.

ah ok, thanks for clearing that up. I'll just have to be patient!

@pelrun is right, there is a general shortage of semiconductors. I got mine from Digikey in small quantities but now temporarily our of order. If anybody finds a source please share it here. Bad time to announce a new open source design ;-)

FYI, I just released a new design of the analyzer which is based on a bare TFT panel (cheaper), Raspberry Pi Pico module (more ram/rom/speed than STM32) and SOIC-8 current sensors that are available on Aliexpress.
