National Semiconductor’s New Amplifier Family have Integrated EMI Filters National Semiconductor Corp. has introduced three new operational amplifiers (op amps) with integrated electromagnetic interference (EMI) filters that maintain the accuracy of analog systems by reducing the effects of radio frequency (RF) interference. The LMV83x op amps deliver the industry’s highest EMI rejection ratio (EMIRR) of 120 dB, thereby eliminating EMI-induced errors. They also feature 3 MHz unity gain bandwidth while operating on only 240 uA of supply current. This yields a power-to-performance ratio of 80 uA per MHz, which places these devices among National’sPowerWise® family of energy-efficient products.Learn more at the National Semiconductor Corp.web site.
