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.
Found in old documentation, this circuit is the receiver for the previous circuit. Components are...
We found this circuit in the 1994 Linear Applications Handbook by National Semiconductor. The...
This circuit switches the capacitors of a digital filter with the 4046 IC (PLL). The circuit was...
