Unused pin of 3.1W Stereo Audio Power Amplifier LM4950

Other Parts Discussed in Thread: LM4950

Diar all,

My customers will use the LM4950 in a single-ended 1-channel systems.
Please tell us about the terminal processing of unused circuit to me.
They consider the following two proposals as a candidate.
Please check the attached PDF file.LM4950_unused_pin.pdf


A-type: 7-pin and 9-pin short
B-type: Connect to GND on the input side of the gain as 1 times

Do you want to recommend either A-type or B-type ?
Or, do you have any other way ?

Thank you and Best regards,
Hiroaki Masumoto
