AD650
Parameters
Input voltage
`V_i`
\(V\)
one shot capacitor
`C_{os}`
\(pF\)
Input resistance
`R_{in}`
\(k \Omega\)
integrator capacitor
`C_{int}`
\(pF\)
Output
one shot time period
\(T_{OS}=C_{OS}\times0.0068+0.3\)
Input current
\(I_{IN}=\frac{V_{IN}}{R_{IN}}\)
integrator voltage
\(\Delta V=T_{OS}\cdot \frac{dV}{dt}=\frac{T_{OS}}{C_{INT}}(1-I_{IN})\)
ramping down time
\(T_I=T_{OS}(\frac{1}{I_{IN}}-1)\)
output frequency
\(f=\frac{1}{T_{OS}+T_{I}}\)
