This detector with ultra-low deviation was found in an American documentation from the 90s. Operational amplifiers are from that time. The power supply must be symmetrical.
This circuit, which in our times would be called a shield, can also be used with other loads. The...
This converter converts signals from the 50 MHz band to the AM band, making it possible to receive...
Other operational amplifiers series, such as the MC34072, MC34074, MC35071, MC35072, MC35074 d...
