Part Number: TPA3250
Other Parts Discussed in Thread: TPA3255, TPA3251,

Hello,

Thank you for reading. When I check pin defination among tpa3250 tpa3251 tpa3255, I find some inconsistency in pdf of 3250. Now I need to make sure the exact order of pins. In pg3, pin 19 20 are defined as m1 m2 but in pg24, pin 2 3 are defined as m1 m2. which is correct from top of chip? actually dot pin is defined as pin1 right?

Looking forward to see.

Kind regard,

Louie, BuddhiAudio

Besides, in schematic of EVA TPA3250, pin 19,20 is defined as M1,M2. While in schematic of EVA TPA3251, pin 3,4 is defined as M1,M2.

What i am using is TPA3250.

so it means pin of TPA3250 and that of TPA3251 3255 are versely defined right?

hello sir,

normally page 3 pin definition should be correct. Let's double check with design & system and go back confirm to you.
