Low noise & precision

Enhance power and signal integrity to improve system-level protection and accuracy

How can power ICs reduce inherent and system noise?

Low-noise low-dropout linear regulators (LDOs) and switching converters, precision monitoring, and reliable protection are fundamental to enabling precision signal chains. For applications such as the battery monitoring of medical, test and measurement, battery monitoring of electric vehicles, and more TI uses dedicated power process technologies and advanced circuit and test techniques that increase accuracy, minimize distortion, and reduce noise across both linear and switching power converters.

Simplifying Power Architectures With Low-Noise Power Devices

Reducing inherent and system noise is critical to enabling high-precision signal chains in demanding electronic systems, but traditional low-noise power architectures often have challenges with power consumption and thermal performance. In this paper, we look at how innovations in low-noise power devices are helping engineers optimize their power architectures.
