The ACPL-796J is an isolated Sigma-Delta modulator designed for current sensing in motor control, solar inverters, and other power electronic applications. Manufactured by Avago Technologies, this device provides reinforced insulation and precise current measurement by converting an analog input signal into a high-speed data stream. This data stream can be processed by a microcontroller or digital signal processor (DSP) to accurately determine the current flowing through the monitored circuit.

Applications:

• Motor Control
• Solar Inverters
• Wind Turbine Inverters
• Power Supplies
• Current Sensing
• Industrial Inverters

Features:

• Isolated Sigma-Delta Modulator: Provides accurate current measurement with reinforced insulation.

Additional Details:

The ACPL-796J typically requires an external clock signal to operate the modulator. The output data stream is a high-speed digital signal that must be decoded by a microcontroller or DSP. The device's accuracy, insulation voltage, and other critical parameters should be carefully verified using the manufacturer's datasheet to ensure proper operation in the target application. It comes in a surface-mount package for automated assembly.
