Rohm op amp ICs feature superior EMI immunity in all bands

Automotive-grade ground sense opamps ar esaid to deliver breakthrough EMI tolerance (noise immunity) for automotive systems using sensors.

Developed using proprietary layout, processes, circuit design technologies, the BA8290xYxx-C series features superior noise immunity that suppresses output voltage fluctuation in all frequency bands to less than ±1%, compared to ±3.5% to ±10% with conventional products. The high noise tolerance can eliminate the need for noise countermeasures such as filters (3 CR filters for the input/output/power supply). This helps to reduce design load while contributing to greater reliability.

The entire lineup is AEC-Q100 qualified, ensuring automotive-grade reliability, and delivers superior current consumption (0.5 mA vs conventional 0.7 mA) and offset voltage (±6 mV vs ±7 mV) in a range of standard package types, channels, and layout – enabling easy replacement with existing products to reduce noise.

Applications include EV/HEV inverters, ECUs, automatic transmissions, electric power steering, automotive lamps, car A/C, EV chargers, car navigation, combination switches, and other vehicle electrical systems and circuits affected by noise.
