BD5469GULAnalog Input Monaural Class-D Speaker Amplifier | Linear | 1 | Active | BD5469GUL is a monaural Class-D speaker amplifier that has integrated ALC function suitable for mobile phones, portable type electronic devices, etc. LC filter at the speaker output is not needed. The IC forms a monaural speaker amplifier using just 3 external components. ALC, short for Automatic Level Control, is a function that automatically adjusts the level of suppression to avoid distortion (clipping) of the output waveform during excessive input. The time until the suppression of the output level is released is called the release time (or recovery time). This IC has a typical release time of 262ms/1dB which suits music play applications. Through Class-D operation, the IC can achieve high efficiency and low power consumption which makes it suitable for battery driven applications. The current consumption in shutdown mode is lowered to 0.01µA (typ.) . Startup time from shutdown mode to active mode is fast and pop noise is minimized which enables it to withstand repeated active and shutdown modes. |

BD54FA1100mA 5.4V, Fixed Output, High-Accuracy LDO Regulator | Integrated Circuits (ICs) | 1 | Active | BD54FA1FP3 is an LDO regulator with output current capability of 0.1A. The output voltage is 5.4V with ±1% accuracy. The SOT89-3K package is most suitable for heat dissipation. As protective function to prevent IC from destruction, this chip has built-in over current protection circuit to protect the device when output is shorted, and built-in thermal shutdown circuit to protect the IC during thermal over load conditions. This product can be used in wide variety of digital appliances. This regulator can use ceramic capacitor, which have smaller size and longer life than other capacitors. |

BD5638Analog Input Monaural Class-D Speaker Amplifier | Amplifiers | 1 | Active | BD5638NUX 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 18dB. 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. |
