Overview
The TDA9860 is a universal HiFi audio processor designed for TV applications. It integrates a crossbar switch to route signals from three stereo or six mono sources (MAIN, AUX, SCART) to loudspeaker, headphone, and SCART outputs. The device features I2C-bus control for volume, balance, bass, treble, and mute functions. Key electrical parameters include a supply voltage of 7.2V to 8.8V, a typical supply current of 25mA, and an operating temperature range of 0°C to +70°C. It provides a signal-to-noise ratio of 85dB and total harmonic distortion of 0.1%.
Applications
- Consumer Audio
- TV sets
Procurement Notes
Verify the package type matches the required design, as the TDA9860 is available in a 32-SDIP (SOT232) through-hole package. Confirm that the application circuit supports the specified 7.2V to 8.8V supply voltage range. Ensure the I2C bus interface complies with the slave transmitter operation mode defined in the datasheet.
Selection Notes
Select this component for TV designs requiring integrated audio routing and processing. It supports up to three stereo input sources and provides dedicated outputs for loudspeakers, headphones, and SCART connectors. The device requires external capacitors for bass, treble, and pseudo-stereo effect adjustments. Verify thermal resistance requirements, as the junction-to-ambient thermal resistance is 60 K/W in free air.
Part Context
The TDA9860 is part of NXP's (formerly Philips Semiconductors) audio special purpose integrated circuit portfolio. It is specifically engineered for consumer television applications, providing a compact solution for managing multiple audio inputs and delivering processed output to various listening environments within the TV system.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official NXP resources for potential obsolescence management or alternative components within the same family.
FAQ
How many audio input sources can the TDA9860 handle?
The TDA9860 can handle signals from three stereo sources or six mono sources, including MAIN, AUX, and SCART inputs.
What is the maximum gain for the loudspeaker channel volume control?
The nominal volume control for the loudspeaker channel ranges from -40 dB to +15 dB.
Does the TDA9860 support pseudo-stereo effects?
Yes, the device supports forced mono with or without pseudo-stereo effects, controlled via the I2C-bus.
