Features

500mW achieved with BTL output
BTL output enables compatibility with 500mW (at 3.6V, 8Ω), making ROHM monaural speaker amps ideally suited for use in portable devices such as digital cameras and camcorders. A broad lineup is offered, including models that operate from 2.4V, in a variety of compact packages (i.e. MSOP8), contributing to end-product miniaturization.
