Transimpedance
∆Vout = ±1V, RL = 100Ω
Output Voltage/Input Current Gain in
ROL open loop of a CFA.
Tmin. < Tamb < Tmax.
For a VFA, the analog of this feature is
the Open Loop Gain (AVD)
-3dB Bandwidth
Small Signal Vout=20mVp-p
Frequency where the gain is 3dB below AV = +1, RL = 100Ω
the DC gain AV
AV = +2, RL = 100Ω
Note: Gain Bandwidth Product criterion is AV = +10, RL = 100Ω
Bw not applicable for Current-Feedback- AV = -2, RL = 100Ω
