Description

The 3650 is an optically coupled differential input isolation amplifier having programmable gain. Noise for the 3650 is specified to 4u Vrms (typ) on the input stage of the isolation barrier and 65u Vrms (typ) on the output stage. The gain of the 3650 is controlled using exernal resistors on the input stage. In low gains the noise performance of the 3650 is dominated by the output stage noise f
