Avago Technologies announces brand new precision optical isolation amplifiers for motor control and existing sensing applications. The particular ACPL-790B, ACPL-790A, and ACPL-7900 devices increase the accuracy and result times of the Avago remoteness amplifier portfolio, even though addressing compact programs with a smaller presence package design. The particular high-precision isolation amplifiers are suitable for current and existing sensing in hvac and brushless dc electric motor drives, industrial inverters, servo engine drives, wind power generation, screen power systems, as well as general analog seclusion.

As current moves through the external resistor inside a motor drive execution, the resulting analogue voltage drop is actually sensed by a great ACPL-790B/790A/7900 isolation amplifier, and yes it allows a proportional output voltage to safely be created on the other hand of the optical seclusion barrier. Competing alternatives based on Hall Effect technology and latest transformer technology suffer electrical parameter variation over temp fluctuations and require a larger footprint in a style.

The ACPL-790B precise  isolation amplifier provides around 0.5% high obtain accuracy, and offer Two hundred kHz bandwidth and One particular.6 usec fast result time to enable capture of transient alerts in short circuit and overload conditions. The devices operate from one 5-V supply that is appropriate for 3.3-V outputs. This specific performance is sent in a compact DIP-8 deal that is suitable for computerized assembly and satisfies worldwide regulatory protection standards.

Additional ACPL-790B/790A/7900 product features:

     High gain tolerance options: ±0.5% (ACPL-790B), ±1% (ACPL-790A), and ±3% (ACPL-7900)
     Extended temperature operation: -40° C  to 105° C
     Agreeable to UL 1577 5000 Vrms/1 instant rating, IEC/EN/DIN EN 60747-5-5 and CSA industrial safety    specifications
