Innovations in low noise and precision technologies are contributing to the vast performance improvements of sensitive medical, test and measurement and electric vehicle battery management systems.

The TPS62913 is a low-noise, low-ripple current mode synchronous buck converter suited for noise-sensitive applications that would normally use an LDO for post regulation such as high-speed ADCs, clock and jitter cleaner, radar and more.

REF70 is a high-precision series voltage reference with the industry’s lowest noise, low temperature drift and high accuracy with a high PSRR, low drop-out voltage and excellent load and line regulation to achieve optimal performance in the signal chain.

The TPS7A94 has the industry’s lowest noise (0.46uVRMS 10 Hz to 100 kHz) with 1% accuracy overall. The ultra-low noise and soft-start feature plus its high PSRR (50dB at 1MHz) and low dropout are excellent for high-precision applications.

The BQ79718-Q1 battery cell monitoring IC achieves unprecedented cell voltage measurement down to 1-mV giving confidence in the ability to charge and discharge the vehicle battery pack beyond existing capabilities.

Improving accuracy and precision, and minimizing system noise is a common challenge for engineers designing a power supply for noise-sensitive systems. Read this article to learn low noise and low ripple techniques for improving system performance.

Whether it's in medical applications, test and measurement equipment or battery monitoring of electric vehicles, mitigating system noise and improving accuracy and precision is critical to enabling precision signal chains.
