General Description

The H11FXM series consists of a Gallium-Aluminum-

Arsenide IRED emitting diode coupled to a symmetrical

bilateral silicon photo-detector. The detector is electri-

cally isolated from the input and performs like an ideal

isolated FET designed for distortion-free control of low

level AC and DC analog signals. The H11FXM series

devices are mounted in dual in-line packages.

Typical Applications

As a Variable Resistor As an Analog Signal Switch

ISOLATED VARIABLE ATTENUATORS

Distortion free attenuation of low level A.C. signals is accom-

plished 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.

ISOLATED SAMPLE AND HOLD CIRCUIT

Accuracy and range are improved over conventional FET

switches because the H11FXM has no charge injection from

the control signal. The H11FXM also provides switching of

either polarity input signal up to 30V magnitude..

AUTOMATIC GAIN CONTROL

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.

MULTIPLEXED, OPTICALLY-ISOLATED A/D CONVERSION

The optical isolation, linearity and low offset voltage of the

H11FXM 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.

ACTIVE FILTER FINE TUNING/BAND SWITCHING

The linearity of resistance and the low offset voltage of the

H11FXM allows the remote tuning or band-switching of active

ﬁlters without switching glitches or distortion. This schematic

illustrates the concept, with current to the H11F1M IRED’s

controlling the ﬁlter’s transfer characteristic.

TEST EQUIPMENT - KELVIN CONTACT POLARITY

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 H11FXM eliminates these troubles while providing

faster switching.
