BD37067FV-ME2

Overview

The BD37067FV-ME2 is a 6-channel audio processor integrated circuit manufactured by ROHM Semiconductor. Designed for automotive applications, it operates within a supply voltage range of 7V to 9.5V and supports I2C bus communication. The device features stereo input selection, signal level adjustment, and output to ADCs. It integrates two-stage post-filters for each of the six channels to reduce out-of-band noise from DAC outputs, alongside volume control and TDMA noise reduction capabilities. The component is qualified under AEC-Q100 standards and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates 6-channel stereo input selector with adjustable signal levels
• Includes built-in 2nd-order post-filters for noise reduction on all 6 channels
• Supports TDMA noise reduction for system simplification
• AEC-Q100 qualified for automotive functional safety support

Applications

• Automotive audio systems
• Car sound processors
• Vehicle infotainment units

Procurement Notes

Verify the specific ordering suffix ME2 against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the design utilizes the correct 40-SSOP-B footprint and that the I2C interface timing matches the controller specifications. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a multi-channel audio processing solution with integrated filtering is required for automotive environments. The 7V-9.5V supply range suits direct vehicle battery connections. Verify that the 6-channel output count meets the system requirements and that I2C control is compatible with the host microcontroller. Consider the SSOP-B40 package constraints for PCB layout.

Part Context
