This handbook describes the BU7625GUW monaural 16‑bit audio codec and video driver LSI, including its audio functions such as microphone and line amplification, BTL speaker output (400 mW@8 Ω), 48‑step electronic volume, and built‑in PLL with selectable reference clocks. It also details the video interface, pin assignments, and package information (VBGA035W040, 4 mm).
Technical sections cover absolute maximum ratings, operating conditions, electrical characteristics (supply voltage, current consumption, SNR, THD+N), serial interface protocol, and pin functional descriptions. The document ends with safety notes, application examples, and contact information for ROHM.
