2 / 16 page  2 LT1509 the multiplier. Line current dead zone is minimized with low bias voltage at the current input to the multiplier. The LT1509 provides many protection features including peak current limiting and overvoltage protection. Imple- mented with a very high speed process, the LT1509 can be operated at frequencies as high as 300kHz.

The LT1509 also provides filtering capability to reject line switching noise which can cause instability when fed into |
