Convergence of three analog technologies: circuit design, layout, and process

ROHM Corporation developed the automotive groundsense OP Amp BA8290xYxx-C series.

This OP Amp series is suitable for core systems such as EV/HEV engines and for automotive electronic systems employing vehicle sensors.

The BA8290xYxx-C series is a product developed by combining ROHM’s three analog technologies: circuit design, layout, and process. The company stated that while the output voltage fluctuation across all frequency bands is ±3.5% to ±10% for general ICs, this product has achieved high noise performance of ±1% or less.

By installing it at the output of devices that output minute signals, such as sensors, the signal can be amplified without being affected by noise, eliminating the need to design separate noise countermeasures using conventional filters.

In addition, the BA8290xYxx-C series exhibits output voltage fluctuations across all frequency bands of ±3.5% to ±10% for general products, while this product displays noise performance of ±1% or less. This product eliminates the need for external noise countermeasure components (three CR filters for power, input, and output), simplifying the noise design for automotive sensor applications that play an important role in the system.

The company stated, "These products comply with the global automotive reliability standard AEC-Q100," adding, "They offer superior current consumption and offset voltage compared to existing ICs, and by featuring a lineup of standard surface-mount packages and channel counts with standard OP Amp terminal layouts, they can easily replace existing products where noise is a concern."
