Additional Details

The ACPL-W61L consists of an LED and a photodiode detector separated by a reinforced insulation barrier. The input voltage or current signal is applied to the LED, which emits light proportional to the input signal. The photodiode detector converts the light into an output current, which is then processed to provide an isolated analog output signal. The device utilizes a sigma-delta modulation technique to achieve high linearity and stability. The reinforced insulation barrier provides galvanic isolation between the input and output circuits, protecting sensitive control circuitry from high voltages and currents. The ACPL-W61L is available in a surface-mount package, making it easy to integrate into space-constrained applications.
