LTC1562-2

The LTC1562 and LTC1562-2 are compact, high performance, “universal” continuous-time filter products, each containing four 2nd order Operational Filter blocks. These low noise, DC-accurate filters let you tailor their center frequencies (f0) over a range of roughly 10kHz to 150kHz (LTC1562) or 20kHz to 300kHz (LTC1562-2) and replace several precision capacitors, resistors and op amps. All frequency-setting ...
