Nisshinbo Micro Devices' operational amplifiers boast exceptional immunity to prevent circuit failure resulting from RF noise interference. These op amps and comparators find widespread use in automotive applications, particularly in amplifying signals from various sensors and current detection. When operational amplifiers in automotive ECUs are exposed to external electromagnetic noises beyond the operating frequency, it can lead to output voltage fluctuations and ECU malfunction. This necessitates the use of operational amplifiers with high EMC performance, especially those highly resistant to RF noise interference.
Traditionally, most products have only implemented EMC countermeasures at the input terminals to address weak EMI immunity. However, Nisshinbo Micro Devices took a different approach, conducting thorough analysis of EMI noise intrusion paths and their impact on each stage circuit of the operational amplifier. This led to optimal EMC countermeasures being applied at each stage, resulting in industry-leading immunity levels at both the power supply terminal and the input terminal. By addressing IC internal circuits, these measures are less affected by chip layout and assembly conditions, ensuring stable and high EMC performance. Ultimately, these products help minimize the risk of design rework after noise evaluation, contributing to reduced total development costs.
