National Semiconductor Corp. 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. |

A new series of high-rated X2 capacitors with up to 45 μF allows the construction of space-saving and low-inductance EMI filters. The number of nonlinear loads in industrial and consumer electronics is increasing continuously. Whether it's a frequency converter, PC or energy-saving lamp - hardly any appliance now draws sinusoidal current from the power network. |
