Recent years have seen a growing number of devices, such as smartphones, tablet PCs, and portable gaming systems, that incorporate sensors to detect acceleration, angular velocity, and other parameters. Sensors are often embedded in applications that convert physical changes to small electrical signals. To make use of these small signals, however, they must be amplified using sensor signal amplifiers, which are positioned downstream of the sensor and require sensitive analog technology to ensure high-accuracy amplification.
Both the BD5291G and BD5291FVE utilize ROHM's industry-leading analog technology, enabling input/output full-swing operation at only 1.7V (vs. 1.8V with comparable devices). In addition, high common-mode rejection ratio results in a small-signal processing accuracy 18 times better than what can be achieved with ordinary low voltage operational amplifiers, making them ideal for sensor signal amplification.
Key Features
1. Low voltage input/output full-swing operation
Low-voltage (1.7V) input / output full-swing operation provides sufficient margin against supply voltage fluctuations. This makes them well-suited for applications with low supply-voltage requirements.
2.High accuracy signal amplification
Low input offset voltage combined with high common-mode rejection ratio (70dB min vs. 45dB min with conventional products) makes it possible to amplify small signals (i.e. from sensors) with greater accuracy.
