Analog Input Monaural Class-D Speaker Amplifiers - BD5632NUX

BD5632NUX is a low voltage drive class-D monaural speaker amplifier that was developed for cellular telephones, mobile audio products and the others. The LC filter of the speaker output is unnecessary and only 3 external components are needed by fixed gain 6dB. Because the efficiency is high and is low consumption power with the class-D operation, it is the optimal for the application of the battery drive. Also Current consumption of 0µA when standby and fast transitions from standby to active with little pop noise make it is suitable for applications that switch repeatedly between suspended and active.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
