Product specification

Audio FM processor for VHS hi-fi audio

TDA9610H

Note

1. The audio distortion is measured with the HID pulse frequency set to 1 kHz (500 Hz input at pin 51). FM signal:

1 kHz HID-pulse frequency is corrected with 26 dB in order to calculate the equivalent distortion at 50 Hz HID-pulse

frequency.
