EVBD-ACPL-C79A

The ACPL-C79X evaluation boards can accommodate either a ACPL-C79B (0.5% tolerance), ACPL-C79A (1% tolerance), or ACPL-C790 (3% tolerance) device on U1, to demonstrate the high linearity and lowoff set capability of Broadcom’s Isolation Amplifier over a wide range of input current conditions. It allows a designer to easily test the performance of the high-precision isolation amplifier in an actual application under real-life operating conditions. Many of the circuit recommendations discussed in Application Note 1078 are implemented on the board. Operation requires merely the addition of a 5V Supply 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.
