M62253BGP#D71J

Overview

The M62253BGP#D71J is a monolithic integrated circuit manufactured by Renesas Electronics Corporation, designed for audio signal processing applications. This component operates within a supply voltage range of 4.5V to 5.5V and features a low-voltage CMOS construction. It integrates multiple functional blocks including a pre-emphasis filter, a tone control circuit with bass and treble adjustment capabilities, and a volume control section. The device supports both stereo and mono input configurations, providing flexible connectivity for various consumer audio systems. It is housed in a 28-pin plastic package.

Feature Summary

• Integrates pre-emphasis filtering and tone control circuits for audio signal conditioning
• Provides independent volume control functionality for stereo or mono inputs
• Supports direct connection to FM tuner modules via dedicated input terminals

Applications

• FM tuner units requiring integrated tone and volume management
• Car audio systems utilizing single-chip audio control solutions
• Home audio equipment needing compact signal processing integration

Procurement Notes

Verify the specific suffix D71J against official Renesas documentation to confirm exact tape-and-reel specifications and moisture sensitivity levels. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements. Cross-reference the manufacturing date code to confirm availability status, as older automotive-grade components may have limited production runs. Confirm that the 5V supply rail matches the system design constraints before procurement.

Selection Notes

Select this component when a single-chip solution for audio tone and volume control is required in automotive or home audio environments. It is suitable for designs prioritizing reduced component count and simplified PCB routing. Consider its operating voltage range and package dimensions relative to the target enclosure space. Evaluate the need for integrated pre-emphasis and tone controls versus discrete alternatives based on system complexity and cost targets.

Part Context

This part belongs to the M62253 series of audio control ICs developed for consumer and automotive electronics. The series is characterized by high integration levels, combining analog audio processing functions into a single package. These components are widely used in applications where space efficiency and reliable audio performance are critical, serving as central control elements for sound output regulation.

Replacement Considerations

Consult official Renesas cross-reference guides for verified substitute part numbers. Direct replacements must match the pinout, voltage specifications, and functional block diagram. Generic equivalents are not recommended due to potential differences in audio performance characteristics and interface timing.
