"Features
* Converts continuous voltage input to discrete .0833 voltage steps.
* Also provides whole step and fourths mode (.1666V and .3332V steps).
* Low cost parts used in the A/D and D/A circuits.
* Adds 12 tone (or whole or fourth tone) musical dimension to S&H outputs.
* Eases sequencer set up by correcting notes to discrete steps.
* Conversion time varies from sub millisecond to 1.26 millisecond (full count)
* This thing is pretty darn fun!
Possible Quirks
* Never let it be said that you won't find a voltage that causes inter-count jitter.
* Minimal chatter on step change with slowly changing input voltage.
Introduction
A voltage quantizer takes a continuously variable input voltage and outputs a stepped (or quantized) voltage. Whereas the input voltage might ramp up from 0 to 1V continuously the output voltage of the quantizer will be discrete steps of .083V. In normal mode this quantizer always starts at digital 1 or .083V. As the input voltage starts to ramp from 0 up to 1 volt the output will step to .1666V, .2499, .3332, etc up to 1.0V. The circuit also features a whole step mode in which the in to out conversion is quantizd to steps of .1666V. It also features a fourth step mode in which the in to out conversion is quantizd to steps of .3332V. Useful with sample and hold circuits to bring voltages into musical scale steps (half, whole or fourths). Useful with sequencers to bring voltages into musical scale steps (half, whole or fourths)."
