Simplified Formulas for Setting the LB11945H CR Circuit Time Constants
The equations below give the rise time, T1, and the fall time, T2, for the CR oscillator circuit.
T1
≈ 0.44C × R (s)
T2
≈ 0.72 × (C × R × 1000) / (R + 1000) (s)
(C : 220 to 4700pF, R = 10 to 150k
Ω)
Set the oscillator frequency using the simplified formulas shown above.
Note that the fall time, T2, for the triangle wave oscillator waveform also defines the noise canceller time.
