The TDA8425 is a monolithic bipolar integrated stereo sound circuit designed for hi-fi audio and television sound applications. It features digital control via the I2C-bus, enabling features such as source and mode selection for two stereo channels, pseudo stereo, spatial stereo, and forced mono modes.
Key audio controls include volume and balance adjustment, with a volume control range from +6 dB to -64 dB in 2 dB steps. It also provides bass and treble control, with bass offering emphasis up to 15 dB and attenuation down to 12 dB, while treble control ranges from +12 dB to -12 dB. A mute function is also integrated.
Electrical specifications include a typical supply voltage of 12.0 V, an input sensitivity of 300 mV, a signal-to-noise ratio of 86 dB, and a total harmonic distortion of 0.05%. Channel separation is rated at 80 dB.
The TDA8425 is available in a 20-lead dual in-line plastic package (SOT146).
