NXP Semiconductors TDA9614H
The TDA9614H is an audio processing IC for VHS hi-fi and linear 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 no external adjustments. When using IR reflow soldering it is recommended that the Drypack instructions in the “Quality Reference Handbook” (order number 9398 510 63011) are followed.FEATURES
