BD5460GUL is a low voltage drive class-D monaural speaker amplifier that was developed for cellular phones, mobile audio products and the others. LC-filter of speaker output is unnecessary, and the number of external components is three. It is suitable for the application of battery drive because of high efficiency and low power consumption. Also, stand-by current is 0µA (typ.), and fast transitions from standby to active with little pop noise. It is suitable for applications that switch repeatedly between stand-by and active.
The BD5460GUL is a low‑voltage, monaural Class‑D speaker amplifier designed for mobile phones and other battery‑driven audio products. It operates without an external LC filter, requiring only three external components, and offers high efficiency with a typical standby current of a few microamps.
