Other Parts Discussed in Thread: LM4940, LM4950

Hi,

Please let me questions in LM4940.

Q1) Is LM4950 usable in "8Ω BTL Loar" ?

Q2) And, I calculated with 3W(8Ω BTL), in case of Po:VDD=14.4V, THD+N=10%.

       do you not have any problem?

Best regards

    Hi Cafain,

    LM4940 is not specified for BTL operation, but LM4950 does.
    LM4950 can be configured for BTL operation requiring only one input signal, you can find this configuration in LM4950 D/S Figure 1.
    Does LM4950 fits in your application?
