Description
The key component of Buchla style Low Pass Gates and many other exotic Buchla/Serge derived designs.
XVive Vactrol analogue optoisolators have an LED as the input element and a photoconductive cell as the output element, the coupled pair acts as an electrically variable potentiometer. These are the parts previously known under the brand name VACTEC, as manufactured by Perkin Elmer and Excelitas.
VTL5C1 – offers 100db dynamic range, fast response time, and very high dark resistance.
VTL5C2 – features a very steep slope, low temperature coefficient of resistance, and a small light history memory.
VTL5C3 – has a steep slope, good dynamic range, a very low temperature coefficient of resistance, and a small light history memory.
VTL5C3/2 – has a steep slope, good dynamic range, a very low temperature coefficient of resistance, and a small light history memory.
VTL5C4 – features a very low “on” resistance, fast response time, with a smaller temperature coefficient of resistance than VTL5C1.
VTL5C6 – has a large dynamic range, high dark resistance, a low temperature coeffecient of resistance, and a small light history memory.
VTL5C9 – has a 112 db dynamic range, fast response time, high dark resistance, but with a more shallow slope and lower “on ”resistance at low (1 mA) drive currents than the VTL5C1.
