HCPL-7800A, HCPL-7800, HCPL-7840 Isolation amplifier evaluation board Description The HCPL-7800A/7800/7840 evaluation board demonstrates the high linearity and low-offset capability of the HCPL-7800A/7800/7840 over a wide range of input current conditions. It allows a designer to easily test the performance of the HCPL-7800A, HCPL-7800 or HCPL-7840 high-precision isolation amplifier in an actual application under real-life operating conditions. Operation merely requires the addition of a 9V battery and a low-resistance shunt resistor on the input side of the isolation amplifier. The board has holes for mounting a through-hole shunt and pads for mounting a surface-mount shunt. The board may also be used for general voltage isolation without any shunt resistor. The isolation circuitry is easily contained within a small area while maintaining adequate spacing for good voltage isolation and easy assembly. The overall size of the evaluation board has been enlarged to allow mounting of feet for stand-alone use (using the 4 drilled holes at the corners of the board). Want to apply for this board?
