    Limitation for safe use: EVMs are not to be used as all or part of a production unit. 2 Overview The INA4290 device is a voltage-output, high-side quad-channel current sense amplifier in a QFN (16) package. As shown in INA4290 Gain Option Summary, the INA4290 has gains that range from 20 V/V to 500 V/V, depending on the gain option that is selected.

    Hardware 3 Hardware The INA4290EVM provides a basic functional evaluation of the INA4290. The fixture layout is not intended to be a model for the target circuit, nor is it laid out for electromagnetic compatibility (EMC) testing. The INA4290EVM is one PCB with five optional PCB cutouts the engineer can use to test each of the five gain options (1 to 5)

    3. Provide a differential input voltage signal to the In+ and In– nodes by connecting the signal leads to the Jx_n pin 1 and Jx_n pin 2 for channel x on the EVM, as explained in Measurements. The INA4290 is a unidirectional current-sensing device because there is no reference pin.

    Collectively, these pads allow user-defined filters for the input pins (IN+ and IN–) and the output pin (OUT) of the INA4290. 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.
