TIDA-01501: supply of opamp U2B and U10B

Amr Elhadidy

Part Number: TIDA-01501

Hi,

opamps U2B and U10B are the same but U2B is supplied from VP_Aux through a 21.5K resistor while U10B is supplied from Vs_Aux through a 0 Ohm resistor. Why are the used resistances the same altough opamps are the same?

Thank you,

Amr

I didn't see any 21.5k resistor. U2A and U10B are directly connected to VP_Aux and VS_Aux by R296(0/J) and JP18(0R).

Hi,

R296(0/J) has a value of 21.5KOhm as seen in the Parameters. But I have to Neglect it then.

Thanks,

please noted that R296 is 0ohm.
