DP LPG is a passive device that does not require power, resistor optocoupler based, or alternative name Vactrol.
This device, without supplying voltage to the control input, almost does not pass the signal, when the control voltage is applied, it changes the amplitude and opens like a VCA amplifier, with a characteristic curve corresponding to the resistor optocoupler, which has a small signal release (LPG envelope), and the memory effect of a resistor optocoupler.
Normally closed gate / VCA
Noise transmission is dark -75db (+ - 10%) with an input signal Sine 1kHz + -5Vp-p in the mode without
cutting the high frequencies.
Since this LPG is passive, the minimum voltage for opening is about 1.8V-2V
The maximum CV source current required for maximum opening is 3mA, operating is less than 1mA
Our LPG use matched pairs of opto-resistors and LEDs to provide excellent speed performance. The
maximum frequency of distinguishable modulation of one signal by another signal is 10 kHz.
