TEA6886HL/V2,518

Overview

The TEA6886HL is a monolithic bipolar integrated circuit designed as an up-level car radio Analog Signal Processor (CASP). It integrates stereo decoding, ignition noise blanking, source selection, and tone/volume control for AM/FM applications. The device operates within a supply voltage range of 7.8 V to 9.2 V with a typical current consumption of 40 mA. Key features include I2C-bus compatible digital alignment for FM noise blanker sensitivity, stereo separation, and High Cut Control. It supports six audio sources, including external stereo inputs, symmetrical inputs, and internal AM/FM signals, providing comprehensive audio processing capabilities.

Feature Summary

• Integrated FM stereo decoder with pilot detector, canceller, and selectable de-emphasis (50/75 μs)
• FM and AM noise blanking with weak signal processing including soft mute and high cut control
• Six-source selector with volume, loudness, bass, and treble controls via I2C-bus
• Analog Step Interpolation (ASI) and Audio Blend Control (ABC) to minimize switching pops

Applications

• Up-level car radio analog signal processing
• AM/FM receiver audio front-ends
• Automotive audio systems requiring integrated stereo decoding and tone control

Procurement Notes

Verify the package type LQFP80 (SOT315-1) and operating temperature range of -40°C to 85°C against specific design requirements. Confirm I2C bus compatibility with the host microcontroller. Check for obsolescence status as this component originates from Philips Semiconductors specifications dated 2003. Ensure supply voltage stability within the 7.8 V to 9.2 V range for proper operation.

Selection Notes

Select this component for applications requiring a single-chip solution for AM/FM audio processing in automotive environments. It is suitable when I2C-controlled digital adjustment of audio parameters like noise blanker sensitivity and stereo separation is required. Consider the 80-pin LQFP package constraints and the need for external capacitors for time constants and de-emphasis networks during PCB layout.

Part Context

The TEA6886HL is part of the Philips/NXP car radio CASP family, often paired with tuners like the TEA6840H. It supersedes earlier data from November 2000. The device provides a complete analog signal processing chain, combining the functions of a stereo decoder, noise blanker, and tone controller into one IC, simplifying the design of high-end automotive audio systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product specification dates from 2003 and originates from Philips Semiconductors, direct replacements should be sought through NXP USA Inc. or authorized distributors based on functional equivalence in automotive CASP applications.
