**Part Number:**TMS320F28377D

**Other Parts Discussed in Thread:**AMC1304M25

hi ！

in controlsuit the example project IDDK_PM_Servo_F2837x_v2, when i used the sdfm to sample the motor current, I have some question about the conversion coefficient show in the follow picture

why the sdfm is 0.8906pu current is 12.5A, the sample resistance is 20mohm, the delta-sigma (ΔΣ) modulator is AMC1304M25, in the datasheet of AMC1304M25 the Specified linear full-scale range is -250mv to 250mv, the Maximum differential voltage input range is -312.5mv to 312.5mv.

why the sdfm is 0.8906pu current is 12.5A?

thank you!
