These parameters are guaranteed by design and are not subject to production testing.
All input control signals are specified with t
All ac characteristic tests are performed in a closed-loop system using an AD8038 I-V converter amplifier except for THD where an AD8065 was used.
C6 is the C6 capacitor shown in Figure 20.
