AF102 Datasheet | National Semiconductor

Description The AF102 is a fourth order elliptic highpass filter designed to reject frequencies below 650Hz. This filter rejects the 350Hz and 440Hz dial tone frequencies present on a telephone line. The unit is fully tuned and requires no external ponents - only input, output and power supply connections.
