Programmable Active Filter ICs Offer Five Configurable Responses

Capable of being configured for low-pass, bandpass, high-pass, notch or all-pass responses, the MSU1HF1 and MSU1HF3 high-frequency, resistor-programmable universal active filter ICs operate at center frequencies up to 100 kHz while drawing a typical 5 mA. The MSU2HF1 and MSU4HF1 work to 500 kHz at a typical 20 mA. These operating frequencies are said to be much higher than previously available for filter ICs.
