PACKAGE OUTLINE Features Electrical parameters guaranteed over 55C to +125C ambient temp. range Description The OLS700 optocoupler consists of one LED optically coupled to two matched photodiode detectors. Photodiode detectors are used for excellent linearity. The photodiode on the input side acts as a feedback device permitting an external feedback loop to ensure constant LED light output. A similar matching photodiode on the output side is used to drive an output circuit that is electrically isolated from the input. A fixed relationship is thus maintained between input and output. Each OLS700 is mounted and coupled in a custom hermetic surface mount LCC ceramic package providing 1000 Vdc electrical isolation between input and output. Device mounting is achieved with reflow soldering or conductive epoxies. 1000 Vdc electrical isolation High reliability and rugged construction Matched photodiodes Excellent linearity 100% hi-rel screenings are offered NOTES: 1. Measured between pins 1, 2 and 6 shorted together and pins 3, 4, and 5 shorted together. TA =25 C and duration = 1 second.
