Digital Isolators are an important element of any circuit, especially when it comes to safety-critical applications. The ADUM2402BRIZ-RL digital isolator is one of the many isolation products available on the market that offers a high-performance, cost-effective solution for isolating digital signals between two circuits.

The ADUM2402BRIZ-RL digital isolator is a small signal isolation device that provides 25ns minimum pulse width resolution and 100kV/μs Common Mode Rejection (CMR). The device is designed to support data transfer through a single digital channel. It contains two input/output channels, one connected to the sending circuit and another connected to the receiving circuit, and performs signal conversion between the two channels in a bidirectional manner.

The ADUM2402BRIZ-RL uses an EMI filter to reduce the incident electromagnetic interference (EMI) noise. This filter can be removed or adjust to accommodate a variety of operating environments. To ensure the highest level of data protection, the device offers low latency, wide control pulse rate range, and wide isolation channel bandwidth.

The ADUM2402BRIZ-RL is available in both SOIC and TSSOP packages. It also features an active power supply, so that the isolation circuitry can be powered separately from the signal circuitry. This enables the device to provide a wide range of input supply voltages, enabling it to operate in a variety of different environments.

The ADUM2402BRIZ-RL can be used to isolate digital signals between a circuit controller and a programmable logic controller (PLC). The device can be used to control the transfer of digital data between two isolated systems, such as between a PLC input and output, or between two separate systems. This makes the device highly suitable for safety-critical applications, such as automotive and medical systems.

The working principle of the ADUM2402BRIZ-RL digital isolator is based on the principle of capacitive and inductive coupling. The device uses two capacitors and two inductors to create an AC signal. Each capacitor is connected to a separate side of the isolation circuit and can convert AC signals into DC signals. The inductor converts the DC signal back to AC, and the resulting voltage is sent to the receiving circuit. Similarly, when a DC signal is sent from the input side of the isolator, it is converted to an AC signal by the inductor, and then sent to the output side, where it is converted to DC and sent to the receiving circuit.

The ADUM2402BRIZ-RL digital isolator is an ideal choice for applications requiring a high degree of signal isolation. The device offers a wide range of input supply voltages, wide control pulse rate range, and a wide isolation channel bandwidth. It also features an active power supply, which enables the device to operate in a variety of different environments. Additionally, the EMI filter helps to reduce the incident electromagnetic interference (EMI) noise. With these features, the ADUM2402BRIZ-RL provides an effective and cost-effective solution for isolating digital signals between two circuits.
