OptoCoupler 1-CH 8-Pin PDIP SMD T/R

OptoCoupler 1-CH 8-Pin PDIP SMD T/R

Manufacturer Part #: HCPL-7840-500E

Alternate Part #: HCPL-7840-500E/BKN

The HCPL-7840 isolation amplifi er family was designedfor current sensing in electronic motor drives. In a typicalimplementation, motor currents fl ow through an externalresistor and the resulting analog voltage drop is sensed bythe HCPL-7840.
