Using the 741 this circuit can be adjusted to values between 1 Hz and 100 kHz. The power supply must be symmetrical. We found it in the Radio Electronics magazine of November 1973.
The first circuit we present is ideal for matching the low impedance of transducers, such as...
Found in Linear Technology documentation, this amplifier requires a symmetrical power source and...
The maximum frequency of this circuit depends on the operational, reaching a few hundred...
