Sometime for BJT biasing purpose we often need a V-I converter, this circuit intended as current supply for the BJT. From academic book we know that there are two kind of V-I circuit:
1. Floating load
2.Non floating load

Making your self tachometer based on LM2907 /LM2917
Dear allhand
Even this circuit maybe just stright forward from application note but we must make sure that pulses fom rotary encoder fall beyond treshold voltage in pin 11.
After i make F-V converter with LM331 , now i wanna make this converter with more dedicated IC the LM2709 ic, below is the pic
