ADVANCE INFORMATION
The functional block diagram of ISOS510 device is shown in Section 7.2. The input signal is transmitted across the isolation barrier using an on-off keying (OOK) modulation scheme. The transmitter sends a high-frequency carrier across the barrier that contains information on how much current is flowing through the input pins. The receiver demodulates the signal after advanced signal conditioning and drives the transistor in the output stage. This device also incorporates advanced circuit techniques to maximize bandwidth and minimize radiated emissions. Figure 7-2 shows conceptual details of how the OOK scheme works.
