Distortion free attenuation of low level A.C. signals is accomplished by varying the IRED current, IF Note the wide dynamic
range and absence of coupling capacitors; D.C. level shifting or
parasitic feedback to the controlling function.
AUTOMATIC GAIN CONTROL
Accuracy and range are improved over conventional FET
switches because the H11F has no charge injection from the
control signal. The H11F also provides switching of either
polarity input signal up to 30V magnitude.

SIGNAL
This simple circuit provides over 70db of stable gain control for
an AGC signal range of from 0 to 30mA. This basic circuit can
be used to provide programmable fade and attack for electronic
music.
ACTIVE FILTER FINE TUNING/BAND SWITCHING
IF1
The optical isolation, linearity and low offset voltage of the
H11F allows the remote multiplexing of low level analog signals
from such transducers as thermocouplers, Hall effect devices,
strain gauges, etc. to a single A/D converter.

The linearity of resistance and the low offset voltage of the
H11F allows the remote tuning or band-switching of active
filters without switching glitches or distortion. This schematic
illustrates the concept, with current to the H11F1 IRED’s
controlling the filter’s transfer characteristic.

In many test equipment designs the auto polarity function uses
reed relay contacts to switch the Kelvin Contact polarity. These
reeds are normally one of the highest maintenance cost items
due to sticking contacts and mechanical problems. The totally
solid-State H11F eliminates these troubles while providing
faster switching.
