Product details

BD37069FV-ME2: Car Audio Sound Processor with Built-in High-Voltage Output & 2nd-Order Post Filter

The BD37069FV-ME2 from Rohm Semiconductor is a car-audio sound processor featuring a 6-stereo-input selector, 6-channel volume control and a built-in 2nd-order post filter to reduce out-of-band noise. It also supports high-voltage output (up to about 5.2Vrms max) and includes TDMA noise reduction features for automotive audio designs.

Product Introduction

The BD37069FV-ME2 is designed for car audio front-end signal conditioning. ROHM describes it as a sound processor with a built-in six stereo input selector, output level adjustment for interfacing to downstream ADCs, and a 6-channel volume circuit.

To improve audio quality, it integrates a 2nd-order post filter that helps reduce out-of-band noise. It also provides a high-voltage output capability (up to about 5.2Vrms max) and supports TDMA noise reduction features to mitigate system noise in automotive environments.
