This is the peak value detection circuit composed of μA741. In all kinds of tests on the physical quantities converting into electric quantities with the sensor, the peak values should be tested when processing waveforms. In figure 8-1 is the peak value detecting circuit, whose detected negative/positive values are ±5V, the peak values are output by A4 and A5. The maintenance time of the circuit is decided by capacitor C1(C2), diode, VT1(VT2) grid and leakage current. The smaller these elements are, the longer the time will be.
