MODE

= 0 V; G = 20 dB; measured in test circuit Fig.4; unless otherwise specified.

Notes

1. With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal

to the DC output offset voltage divided by R

L

.

2. The DC output voltage with respect to ground is approximately 0.5

× V

CC

.
