nents and it is not affected by internal process
spreads.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers according to the SRS labs specification.
Control of all the functions is accomplished by se-
rial bus. Thanks to the used BIPOLAR/CMOS/
DMOS technology, Low Distortion, Low Noise and
DC stepping are obtained.
