electric druid LOOPENV IC, bag of 2

this is a bag containing (2) two of the electric druid LOOPENV 1B digital IC

With compliments to Tom Wiltshire, from his website www.electricdruid.net:

"This chip is a development of my earlier VCADSR envelope generator. Whilst that chip had both GATE and TRIGGER inputs, this chip replaces the TRIGGER input with a MODE CV that allows selection of normal ADSR, Gated looping, or full LFO-style Looping modes.

Typical ADSR output from looping envelope chip based on PIC 16F684
Typical ADSR output from looping envelope chip based on PIC 16F684

The LOOPENV chip keeps the other features of the original VCADSR, like the LEVEL CV which controls the output level and can act as an 'envelope depth' control, and the TIME CV which shortens the overall time of the whole envelope. The TIME CV makes an excellent modulation input for either envelope modulation or LFO frequency modulation.

Full details are in the datasheet below, but the envelope times range from 1mS through to 10Secs, in 4 even decades, and all control voltages run from 0-5V.

There is also a digital input which selects either a 'traditional' exponential envelope shape, or a early-digital-era linear envelope."
