GENERAL DESCRIPTION

The TDA9610H is a dual audio FM processing IC for VHS

hi-fi audio, digitally controlled via the I2C-bus. The

FM (de)modulator and peak noise reduction functions are

highly integrated, resulting in few external components

and adjustments.

In addition special functions for audio editing, mixing and

dubbing have been implemented.

ORDERING INFORMATION

Note

1. When using IR reflow soldering it is recommended that the Drypack instructions in the

“Quality Reference

Handbook” (order number 9398 510 63011) are followed.
