Migrating to the LM811

How to migrate from the LM820/821/822/823 to the LM811?

The LM811 and LM820/821/822/823 have the same dimensions of 25mm x 12mm x 2mm and the USB interface (pin 2 to pin 5) are in exactly the same position.

When moving to the LM811, consider the following:

  • Pin 1 and Pin 6 have different pin assignments to LM820/821/822/823 .
  • The LM811 has extra pins for a PCM interface. If PCM is not required, this will not affect the design.

Please refer to the datasheets for further information.
