Photodiode isolation amplification circuit uses the photodiode to provide a reliable power supply isolation between the signal path and the two channels of the power supply. IS0212P is a low-cost miniaturized transformer-coupled isolation amplifier circuit. The chip uses two high-efficiency small toroidal transformer and provide reliable isolation between the signal path and the two channels of the power supply. Figure shows the typical application of IS0212P in optical detection, the photodiode is added to the two inputs of BPW21 and OPAl28 (N1) and forms the I / U resistor gain, it uses a larger feedback resistor.
