This home stereo amplifier circuit using STK4241V. This home stereo amp is equiped with STK4241V wich is a thick film hybrid IC, AF Power Amplifier (Split Power Supply) (120W+120W min, THD = 0.08%).
Home Stereo Amplifier Using STK4241V
Simple Microphone Preamplifier
This simple microphone preamplifier circuit can use between your microphone and stereo amplifier. This amplifier microphone suitable for use with normal home stereo amplifier line/CD/aux/tape inputs. This microphone preamplifier can take both dynamic and electret microphone inputs (preamplifier provides power foe electret microphone elements).
Photodiode Amplifier Circuits with OPA128
The OPA128 ultra-low bias current operational amplifier achieves its 75fA maximum bias current without compromise. Using standard design techniques, serious performance
trade-offs were required which sacrificed overall amplifier performance in order to reach femtoamp (fA = 10E–15 A) bias currents.
40-900 MHz TV Signal Amplifier
Here's a small signal amplifier circuit which covers the broad band frequencies from 40 to 900 MHz. These frequencies include TV in VHF and UHF and also the radio broadcasting frequencies in the 88 - 108 MHz FM band. It is connected between the antenna and the input of your receiver and boosts the signals by up to 20 dB.
