Overview
INTEGRATED CIRCUITS DATA SHEET TDA8426 Hi-fi stereo audio processor; I2C-bus Product specification File under Integrated Circuits, IC02 March 1991 Philips Semiconductors Product specification Hi-fi stereo audio processor; I2C-bus GENERAL DESCRIPTION The TDA8426 is a stereo sound circuit with a loudspeaker channel facility, digital controlled via the I2C-bus, for application in hi-fi audio and television sound.
Reduced spatial antiphase crosstalk (30%) makes the device especially suitable for application in projection television receivers.
Features • Source and mode selector for two stereo channels • Pseudo stereo, spatial stereo, linear stereo and forced mono switch • Volume and balance control • Bass, treble and mute control • Power supply with power-on reset QUICK REFERENCE DATA PARAMETER Supply voltage (pin 4) Input signal handling Input sensitivity full power at the output stage Signal plus noise-to-noise ratio Total harmonic distortion Channel separation Volume control range Treble control range Bass control range PACKAGE OUTLINE 20-lead dual in-line; plastic (SOT146); SOT146-1; 1996 November 29.

FUNCTIONAL DESCRIPTION Source selector The input to channel 1 (CH1) and channel 2 (CH2) is determined by the source selector.
The selection is made from the following AF input signals: • IN1 L (pin 18); IN1 R (pin 20) or • IN2 L (pin 1); IN2 R (pin 3) Mode selector The mode selector selects between stereo, sound A and sound B (in the event of bilingual transmission) for OUT R and OUT L.
Volume control and balance The volume control c...
