Product details
Product Introduction
The BD37543FS-E2 belongs to ROHM's sound processor family with built-in 3-band equalizers. ROHM highlights parametric EQ tuning without external components and series-level control software reuse for development efficiency.
In practical designs, it sits between input sources (radio/BT/AUX/DSP) and downstream amplifiers, providing tone shaping and level management while improving overall BOM and board-space efficiency.
Key Benefits
Integrated bass/mid/treble-style tuning for fast acoustic voicing.
Internal EQ reduces external analog tone networks and wiring complexity.
Common control software approach improves reuse and reduces time-to-market.
Centralized register-based control simplifies calibration and production tuning.
Technical Features
Analog audio processing IC for tone control and signal conditioning.
Adjust tone via internal parametric equalizer blocks (per ROHM description).
Verify the exact control interface and register map in the latest datasheet for your suffix.
