5.1 R2_n, R3_n, R4_n, R6_n, R7_n, R8_n, C2_n, C3_n, C4_n, C5_n

R2_n, R3_n, R4_n, R6_n, R7_n, R8_n are factory-installed 0-Ω 0603 resistors.

C2_n, C3_n, C4_n, C5_n are not populated.

Collectively, these pads allow user-defined filters for the input pins (IN+ and IN–) and the output pin (OUT) of the INA2290. If a filter is desired, remove these resistors and replace them with > 0-Ω SMT resistors and populate the capacitor pads with capacitors. Consider the input bias current of the device when using input filtering.
