Hello Michiaki,

Acs for this device is 1

RRFBB should be RFBB, this is a typo in these 2 formulas.

fcross: yes, this is the resistor Rs in Figure 3 (sorry, but the pin is named CS, so the failure is coming from there).

In the next review of the document we will update all this.

Best regards,
Brigitte

Hello Michiaki,

This is the gain of the current sense amplifier. For this device it is 1.
