Digital isolators are designed to increase the electrical insulation between two circuits, providing a reliable, energy-efficient solution to noise and interference in sensitive application. ADUM1245ARSZ-RL7 is a common digital isolator in the market, which provides superior signal isolation and excellent bit-error rate (BER) performance. This article will discuss the application field and the working principle of ADUM1245ARSZ-RL7 digital isolator.

Application Field

ADUM1245ARSZ-RL7 digital isolator is an optically coupled transceiver that provides electrical isolation and noise rejection between two circuits. It is mainly used for signal isolation across a wide range of applications, such as medical and industrial equipment, as well as test and measurement systems. The transceiver supports LED-based signal transmission and data communications between two separated systems without any potential interference.

ADUM1245ARSZ-RL7 digital isolator is designed to handle harsh industrial conditions. The galvanic isolation provided by the device provides added protection between circuits that would otherwise be exposed to transients. By isolating two systems from one another, the device can prevent potential damage from EMI noise or sudden voltage spikes. In addition, it can offer superior data transmission accuracy, allowing for higher data throughput rates while mitigating common signal errors and noise.

Working Principle

ADUM1245ARSZ-RL7 digital isolator is based on optical waveguide technology and uses infrared light pulses and light detectors to transmit and receive data signals. It is composed of two optically coupled data transceiver modules, consisting of an LED transmitter and a light detector, with a high precision optical lens in between. The two transceiver modules are isolated from each other by a solid-state insulation barrier. By using the optical transceiver modules, the device can effectively provide electrical isolation and superior noise rejection, protecting the sensitive components from interference in the system.

The LED transmitter converts the logic signal from the source circuit into electrical pulses, which are then converted into light pulses by the light detector on the receiving module. The light pulses then pass through the optical waveguide lens and are detected on the receiver side, where the signal is then converted back to a logic level signal. The optical waveguide is designed to reduce signal error rate and ensure higher data transmission accuracy.

The ADUM1245ARSZ-RL7 digital isolator is a low-power device, which requires minimal power to operate. It offers wide operating temperature range and high common-mode transient immunity, making it an ideal choice for mission critical applications.

In conclusion, the ADUM1245ARSZ-RL7 digital isolator is a reliable, energy-saving solution for signal isolation. It is widely used in a variety of harsh industrial applications and offers superior signal isolation and excellent bit-error rate performance. With its high precision optical waveguide, the device can effectively protect the system from interference and provide accurate signal transmission.
