3-1/2 Digit LED Voltmeter with Low Component Count Using Common Cathode
Display.

Alternate Oscillator Circuits.
Note
1: For VREF = 2000V; V: 1.999V full scale.
2: For VREF = 200 mV; V: 199.9 mV full scale (change 470 kΩ to R = 27 kΩ and decimal point position.
3: Peak digit current for an eight displayed is 7 times the segment current:
*To increase segment current capability, add two 75491 ICs between 14511B and resistor network.
The use of the 1413 as digit driver increases digit current capability over the 75492.
**V can range between -2.8V and -11V.
