8.4.4 Output Voltage Dynamic Range

With its large output current capability and its wide output voltage swing of ±3.9 V typical on 100-Ω load, it is easy to forget other types of limitations that the VCA824 can encounter. For these limitations, careful analysis must be done to avoid input stage limitation: either voltage or IRG current. Note that if control pin VG varies, the gain limitation may affect other aspects of the circuit.
