TDA9853H is an I2C-bus controlled economic BTSC stereo decoder and audio processor, featuring Voltage Controlled Amplifier (VCA) noise reduction circuit, stereo or mono selectable at the AF outputs, stereo pilot PLL circuit with ceramic resonator, automatic pilot cancellation, and I2C-bus transceiver.
This datasheet describes the TDA9853H, a bipolar‑integrated BTSC stereo decoder and audio processor intended for TV sets, VCRs, and multimedia PCs. It includes functional blocks such as the pilot detector, dematrix, volume‑controlled amplifier, and automatic volume level control.
The document contains ordering information, a quick reference table of electrical characteristics, pin‑out diagrams, component values, and detailed descriptions of features like volume control range, bass/treble adjustment, mute operation, and thermal characteristics.
| Supply voltage (VCC) | 7.8 V – 9 V |
|---|---|
| Supply current | 25 mA – 45 mA |
| Total harmonic distortion (THD) | < 0.5 % |
The device operates from 7.8 V up to 9 V supply voltage.
The volume can be adjusted from +12 dB down to –63 dB in 1 dB steps, ending with a mute step.
