The Model IAlt4 IsolationAmplifier is an ultra-
compactmoduleoffering high linearity,2500-Voltinput/
output isolation,126dB common-mode
rejection,exter-
nally programmable
gain, a floating internalsupply for
poweringan externaltransducer,
and externalsynchroniza-
tion of the internaloscillatorusedin obtainingthe input
isolation.Its 0. I q0 linearityassures
compatibilitywith
l0-bit data acquisition
systems,
and input voltagenoiseis
held to lpV, l0 Hz to I kHz, with l0 pA maximum currenl
noisefor the samerange.The internaloscillatorusedto
providemodulationand demodulation input isolation
for
can be synchronized
with thoseof associated
Model IAl84
amplifiersby an externaltrigger,to preventimpositionof
phenomena the output signal.An inde-
beat-frequency

pendent + l5 VDC, + l5 mA supplyin the input section,
with the samevoltageisolationas the input, can be usedto
power an externaltransducer preamplifier.
