DESCRIPTION
The LT®1319 is a general purpose building block that contains all the circuitry necessary to transform modulated photodiode signals back to digital signals. The circuit’s flexibility permits it to receive multiple modulation methods. A low noise, high frequency preamplifier performs a current-to-voltage conversion while rejecting low frequency ambient interference with an AC coupling loop.
