They are ideal for video isolation when combined with their application circuit Figure? These single channel optocouplers are avail? Pin DIP and Widebody package configurations.

High voltage gain[1]: 2. Low GV temperature coefficient: Highly linear at low drive currents? High-speed AlGaAs emitter? Safety approval: UL Recognized — ? Video isolation for the follow? Low drive current feedback element in switching power supplies, e. Analog signal ground isolation? To order, choose a part number from the part number column and combine with the desired option from the option column to form an order entry.

Option datasheets are available. Contact your Avago sales representative or authorized distributor for information. Measured from input terminals to output terminals, shortest distance path along body. Through insulation distance, conductor to conductor, usually the direct distance between the photoemitter and photodetector inside the optocoupler cavity.

Measured from input terminals to output terminals, along internal cavity. VIORM x 1. Maximum values allowed in the event of a failure,? Case Temperature TS?? Note: Isolation characteristics are guaranteed only within the safety maximum ratings which must be ensured by protective circuits in application.

Test Conditions? Parameter V? Device Min. Units Test Conditions Fig. Maximum variation from the best fit line of IPB vs. IF expressed as a percentage of the peak-to-peak full scale output. Device considered a two-terminal device: Pins 1, 2, 3, and 4 shorted together and Pins 5, 6, 7, and 8 shorted together.

Flat-band, small-signal voltage gain. The frequency at which the gain is 3? Differential gain is the change in the small-signal gain of the optocoupler at 3. Differential phase is the change in the small-signal phase response of the optocoupler at 3.

The THD of the isolated video circuit is measured using a 2. In accordance with UL , each optocoupler is proof tested by apply? Base photo current test circuit Figure 3.

Base photo current frequency response test circuit Figure 4. Input current vs. Base photo current vs. Small-signal response vs. Current transfer ratio vs. Base photo current variation vs. Normalized voltage gain vs. Normalized base photo current vs. Phase vs. Isolation mode rejection ratio vs. DC output voltage vs. Output buffer stage for low impedance loads Figure If the application circuit in Figure 4 is used, then potentiom? Design Considerations of the Application Circuit The app?

Most important of these features is peaked response of the detector circuit that helps extend the frequency range over which the voltage gain is relatively constant. The number of gain stages, the overall circuit topology, and the choice of DC bias points are all consequences of the desire to maximize bandwidth performance. INp-p 3 on VE. F p-p p-p p-p p-p?
