NOTES
1Figures given are percent of full scale (e.g., 0.01% = 1 mV).
2dBc refers to deciBels relative to the full-scale input (carrier) level of 7 V rms.
3See Figure 10 for test circuit.
All min and max specifications are guaranteed.
Specifications subject to change without notice.
(TA = +25 C, +VS = VP = +15 V, –VS = VN = –15 V, RL ≥ 2 k )
