TLP115 is a high-performance optical isolator produced by Toshiba. It has the characteristics of high isolation voltage, high switching speed, low power consumption, small size, and easy to use. It is mainly used in microprocessor system interfaces, digital isolation, A/D, D/A conversion, computer peripheral interfaces and ground loop elimination.
The TLP115 is a miniature surface‑mount photocoupler that combines a GaAs infrared LED with a high‑gain, high‑speed shielded photodetector. It provides digital isolation for A/D and D/A conversion, computer‑peripheral interfaces, and ground‑loop elimination.
