The HCPL-788J-500E is an optically isolated amplifier that is designed and manufactured by Broadcom. It is a quad non-inverting amplifier module with a voltage range of 4.5 to 5.5 volts. It features integrated high speed gallium arsenide infrared emitting diodes, which are designed to transfer data with high electrical noise immunity and wide common mode transient immunity. This amplifier module also provides high current output, low saturation voltage, and low power consumption. It is suitable for using in many industrial applications such as motor control, DC or AC power control, and PWM motor control.
