The HCPL-1458 resolves this issue by implementing a . By using a dedicated photodiode array to capture the optical emission from the GaAsP LED and feeding that directly to an integrated high-gain amplifier stage, the device dramatically isolates and reduces internal capacitances. This specialized design structure allows the device to function up to a hundred times faster than conventional alternatives. Primary Applications
