LV3328PM-TLM-E

Audio Special Purpose Overview

The Sanyo LV3328PM-TLM-E is a six-channel electronic volume integrated circuit designed for automotive audio applications. It features an I2C and logic interface for digital control of audio signal attenuation. The device operates within a supply voltage range of 7V to 9.5V and supports an operating temperature range from -40°C to 85°C. It provides 80dB of volume control specification and is housed in a 44-BQFP (10x10mm) surface-mount package.

Audio Special Purpose Feature Summary

• Six-channel electronic volume control with 80dB specification
• I2C and Logic interface for digital volume adjustment
• Automotive grade qualification for vehicle integration
• Wide supply voltage operation from 7V to 9.5V

Audio Special Purpose Applications

• Automotive audio systems
• Multi-zone sound distribution
• Vehicle infotainment volume management

Audio Special Purpose Procurement Notes

Verify the specific suffix TLM-E against official Sanyo documentation to confirm packaging details and material compliance. Ensure the 44-QIPM package footprint matches the target PCB design. Confirm that the 7V-9.5V supply requirement aligns with the vehicle's electrical system specifications before procurement.

Audio Special Purpose Selection Notes

Select this component when a multi-channel, digitally controlled volume solution is required for automotive environments. The 6-channel capacity supports complex audio routing. Verify that the I2C bus speed and logic levels are compatible with the host microcontroller. The wide input voltage range accommodates typical automotive power fluctuations.

Audio Special Purpose Part Context

This part belongs to the Sanyo electronic volume IC family, specifically engineered for high-reliability automotive audio applications. The 44-pin BQFP package allows for compact integration into vehicle head units or amplifier modules. It serves as a dedicated component for managing audio signal levels across multiple speaker zones.

Audio Special Purpose Replacement Considerations

Check for direct pin-to-pin replacements within the Sanyo or ROHM portfolio that maintain the 6-channel architecture and 44-BQFP package. Verify that any substitute supports the same 7V-9.5V operating range and I2C interface compatibility.
