The ripple filter is specially deisgned to filter out 50 Hz ripple signals from audio lines. A 50 Hz noise is usually found in european countries. In many cases, it is not possible to remove the cause of ripple noise. The featured active filter notch filter solves the problem in suvh cases. It allows the desirable signal to pass through with minimal attenuation. The Q factor of the filter is 10 at the inductivity value of 150 H.
This HiFi headphone amplifier circuit design is normally used to drive a headphone with a relative low impedance. It provides one watt power output and it can also be applied as an output stage for preamplifiers in conjuction with active loudspeakers boxes. The headphone amp is composed of an OP-AMP and an additional transistor amplifier. Input signals pass through a low pass filter composed of R1-C2. Its applification together with a relatively “fast” OPAMP provides a low distortion factor.
LF356a General Description:
These are the first monolithic JFET input operational amplifiers to incorporate well matched, high voltage JFETs on the same chip with standard bipolar transistors (BI-FET™ Technology).
These amplifiers feature low input bias and offset currents/low offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common-mode rejection. The devices are also designed for high slew rate, wide bandwidth, extremely fast settling time, low voltage and current noise and a low 1/f noise corner.
