HCPL-7840-300E Broadcom, Isolation Amplifier, 5 V, 8-Pin PDIP SMD

The range of isolation amplifier optocouplers from Avago Technologies is ideal for industrial environments where the optocoupler is used to insulate high voltages and isolate any unwanted signals. Sigma-delta modulator technology allows the current and voltage sensor families to provide precise measurements of phase current and bus voltage in motor drives, power inverters and voltage signals in general isolation circuits. These isolation amplifiers offer high CMR (common mode rejection) performance and built-in safety insulation. They are a suitable alternative to the Hall Effect isolation amplifiers, for current and voltage sensing in power converters.

Various types available including:
precision isolation amplifiers
miniature isolation amplifiers
precision optically isolated voltage sensors
isolated linear sensing ICs
isolation amplifiers with short circuit and overload detection
automotive isolation amplifiers
