It takes analog audio inputs and applies bass, treble, volume, balance, and fader adjustments digitally, then outputs the processed signals. The 7V to 9.5V supply rail is typical for car-radio head units and consumer preamp stages. Five independent channels let it handle a 2.1 system (front left/right, rear left/right, subwoofer) or a 5.0 surround stage without external muxing. The I²C interface keeps the control wiring to two lines — SDA and SCL — regardless of channel count. The industrial temperature floor means it also works in outdoor kiosk or dashboard applications that see cold starts. ## Package, footprint, and storage Housed in a 32-SOP body measuring 0.213\" (5.40 mm) wide — the supplier device package is designated 32-SSOP-A. This is a standard surface-mount footprint with 0.80 mm pitch typical for SSOP-32. The reel format (Tape & Reel) is the usual shipping method; cut tape is also available for prototype or low-volume builds. Store the reels dry — SSOP packages are moisture-sensitive. If the floor life has been exceeded, a 48-hour bake at 125°C is the standard recovery before reflow. The narrow 5.40 mm body width means the part sits comfortably in a standard SSOP-32 solder paste stencil aperture. ROHM lists the BD37544FS- as Active with ROHS3 compliance. This is a current-production part, not an EOL candidate — the line can be designed in without an immediate obsolescence risk. No official second-source or pin-compatible cross-reference exists from another manufacturer — the I²C register map and pinout are ROHM-specific.","metaTitle":"BD37544FS-E2 Audio Tone Processor, 32-SSOP-A, ROHM","metaDescription":"ROHM BD37544FS-E2 Audio Tone Processor in 32-SSOP-A. 5-channel I²C-controlled processor for automotive/consumer audio.
