Hello,

My customer has a question about LMH6882.

[Q]

LMH6882 is Dual Amplifier.

But they are not going to use one.

(I understand LMH6881 is Single Amplifier. They can use LMH6881.)

Please tell me how to connect of unused input pin of unused amplifier.

I think unused output pin of unused amplifier can leave open.

Hello Hiroshi san

The unused inputs can also be left floating. If desired then can be connected to ground with bypass capacitors, but this is not necessary. The unused amplifier can also be set to a lower gain, this will minimize noise on the output pins and reduce any chance for noise to couple into the active channel.

Regards,

Loren
