compactmoduleoffering _high linearity,2500-Voltinput/
output isolation,126dB common-moderejection,exter-
nally programmablegain, a floatinginternalsupplyfor

tion of the internaloscillatorusedin obtainingthe input
isolation.Its 0.I ^q0 linearityassurescompatibilitywith
l0-bit data acquisitionsystemsa, nd input voltagenoiseis
heldto lpV, l0 Hz to I kHz, with l0 pA maximumcurrenl
noisefor the samerange.The internaloscillatorusedto
providemodulationand _{demodulationfor input isolation}
can be synchronizedwith thoseof associatedModel IAl84
amplifiersby an externaltrigger,to preventimpositionof
