Audio Special Purpose Procurement Notes

Verify the specific ordering suffix TLM-E against official Sanyo documentation to confirm tape-and-reel packaging details. Ensure the 44-QIPM footprint matches the target PCB layout. Confirm that the 7V-9V supply requirement aligns with the vehicle's electrical architecture. Check for any specific handling precautions related to the Bi-CMOS technology used in this automotive-grade component.

Audio Special Purpose Selection Notes

Select this component when designing automotive audio systems requiring integrated multi-channel volume control. The 6-channel capability reduces external component count compared to discrete solutions. Ensure the design accommodates the 7V-9V supply rail and the 44-pin BQFP thermal requirements. Verify compatibility with the host microcontroller's logic levels for the interface signals.

Audio Special Purpose Part Context

This part belongs to Sanyo's family of Bi-CMOS LSIs for car audio. Similar devices include the LV3313PM and LV3319PM, which also serve as electronic volume controllers. These components are engineered to replace mechanical potentiometers, offering precise digital control and reliability in harsh automotive environments.

Audio Special Purpose Replacement Considerations

Direct replacements may include other Sanyo/ON Semiconductor LV series volume ICs such as the LV3313PM or LV3319PM. Verify pin-to-pin compatibility and software register configurations before substitution. Alternative manufacturers may offer similar 6-channel volume controllers, but interface timing and supply voltage specifications must be matched.
