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 )
