Product specification
TDA8426
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
