The World's First Noise-Tolerant Op-Amps Unprecedented noise immunity contributes to improved reliability and simpler designs in automotive sensor applications



With the BA8290xYxx-C series, ROHM offers automotive-grade op-amps featuring superior noise immunity. Output voltage fluctuation in all frequency bands is suppressed to less than ±1%, compared to ±3.5% to ±10% with conventional products. This makes it possible to amplify sensor signals without the need for noise countermeasures, significantly reducing design load and contributing to greater reliability. This new series is ideally suited for automotive applications where sensors are used along with the core systems for electric vehicles (EV) and hybrid electric vehicles (HEV).

Kionix's New KX220 Analog Accelerometers for the Industrial Market Compact high-bandwidth design supports up to +/-40g, ideal for vibration sensing and shock detection in industrial applications



ROHM Group company Kionix announced the release of the KX220 series of medium-g tri-axis analog accelerometers. The initial launch will consist of two models: the KX220-1071 and KX220-1072, featuring +/-20g and +/-40g ranges, respectively, and support a maximum signal bandwidth (-3dB) of 8kHz. Both sensors include self-test functions, consume only 0.25mA at 3.3V, and are offered in a compact 10pin 3mmx3mm LGA package.

Transfer Functions of DC/DC Converters: Sharing Transfer Functions Among Control Systems

PCB Layout of DC/DC Converters: Placement of Thermal Vias

Converter Transfer Functions: An Introduction

From here, we embark on a new chapter, “Transfer Functions for Converters”. Using the concepts introduced in the previous chapter on “The State-Space Averaging Method“, we derive transfer functions for various control modes.

Thermal Vias

The use of thermal vias is well known as a method that uses the circuit board to improve the heat dissipation of surface-mount components. Structurally, a penetrating hole is opened in the board, and for double-sided boards with a single layer, copper foil is used to connect...
