New EMARMOUR™ 2 Channel High-Speed Op Amp

ROHM introduces the availability of a 2 channel high-speed ground sense CMOS op amp, BD77502FVM, optimized for consumer and industrial equipment requiring high-speed sensing – such as industrial measurement and control systems.

The proliferation of the Internet of Things (IoT) in recent years has led to a significant increase in the number of electronic components used for advanced control in a variety of applications. This trend towards greater electronics density is leading to noisier environments, making it extremely difficult to implement designs with electromagnetic compatibility (EMC). Op amps play a critical point role because they quickly amplify small signals (from sensors) in many detection systems that provide safety. In addition, printed circuit board design can also be problematic for conventional op amps that are susceptible to oscillation due to capacitive loads (i.e. from wiring).

To mitigate noise issues common with conventional op amps, ROHM has developed the EMARMOUR™ series featuring superior noise tolerant op amps. The first groundbreaking member of the EMARMOUR family was the BD77501G single channel high-speed CMOS op amp that leveraged the original Nano Cap™ technology to prevent oscillation caused by load capacitance (more info).
