Device Structure

44-lead LQFP plastic package, surface mount type for PCB assembly.

Optimized for compact automotive audio design.

I²C digital control interface.

Internal circuits for processing stereo audio signals.

Performance Characteristics

Reliable operation over automotive-grade temperature range.

Handles 2 channels of audio data with real-time processing.

Low power consumption within supply voltage range.

Stable I²C communication for quick adjustments.

Supports complex signal processing functions typical in car audio systems.

Application Environments

Automotive digital audio systems.

Industrial audio processing modules requiring robust performance.

Specialized embedded systems requiring two-channel audio signal manipulation.

Selection Guidelines

Consider for designs requiring automotive-grade audio signal processing in a compact form.

Choose only if system supply voltage matches 7.5V to 10V range.

Confirm compatibility with I²C system control schemes.

Check mounting capability on surface mount PCBs.

Since the part is obsolete, verify future availability for long-term projects and maintenance.

Usage Considerations

Requires careful supply voltage regulation between 7.5V-10V.

Observe proper handling and moisture sensitivity precautions (MSL 3, 168hr).

Integrate with I²C bus and confirm system compatibility before design.

Package thermal design should manage -40°C to 85°C operating range.

Plan obsolescence management since product is not recommended for new designs.

Potential Equivalent/Replacement Models

Obsolete status means no direct drop-in replacement from manufacturer.

Comparable audio signal processor ICs may exist with similar channel count and I²C interface, but pinout, performance, and package variations likely.
