LOW-LEVEL VIDEO DETECTOR
The TDA1330 is a monolithic integrated circuit
designed for use in both colour and monochrome
television receivers. It is designed to
replace the third IF stage, the detector, the
video buffer and the AFC buffer. An important
feature is the extremely linear video characteristics
and wide band width.
