In the datasheet for the BC127 there is a note about adding caps to the speaker output lines or units that are not version 4. Version 4 units will not need these caps it says.
Is anybody buying v4 chips from Digikey now?

I talked with some application engineers at Digikey and verified that all BC172’s in stock (both under the BlueCreation and Sierra Wireless manufacturer tags) are indeed V2.
