The TAA865 integrated circuit used in this 1986 project is no longer common today. The circuit is a documentation of the time and the time is given by RC that has indicated the maximum values.
In this circuit the gain decreases as the input signal intensity increases. The circuit is from a...
This circuit was found in an American 1980s documentation. Dual FETs can be replaced by single...
