This circuit appeared in the June 1990 issue of Radio Electronics magazine. Integrated circuits must be equipped with heatsinks. Current and voltage depend on the ICs used.
In this amplifier, the supply voltage is 35 V and the input resistance is 2k2. Equivalent...
This high speed laser diode driver was found in a 1980s documentation. Power FETs can be replaced...
This instrumentation amplifier with differential inputs was found in documentation from the 90s....
