All rights reserved. 21.Sep.2016 Rev.003 TSZ22111 • 14 • 001 www.rohm.com Low Power Consumption Class D Amplifier 9W+9W Analog Input Class D Speaker Amplifier BD28412MUV General Description BD28412MUV is a 9W+9W stereo (or 18W monaural) class D amplifier, developed for battery equipped speaker systems such as wireless speakers. This IC is incorporated with a precise oscillator to generate multiple switching frequencies that can avoid the AM radio interference. In addition, 2.1Ch audio system can be realized by master and slave operation without beat noise caused by interference between two ICs. Furthermore, this IC achieves lower power consumption that eliminates the need for an external heat sink. Features Analog Differential Input Low Standby Current Output Feedback Circuitry Prevents Sound Quality Degradation Caused by Power Supply Voltage Fluctuation, Achieves Low Noise and Low Distortion, Eliminates the Need of Large Electrolytic-Capacitors for Decoupling Power Limit Function (Linearly-programmable) Selectable Switching Frequency (AM Avoidance Function) Synchronization Control is Supported (Selectable Master and Slave Operation) Parallel BTL (PBTL) is Supported Wide Voltage Range (VCC=4.5V to 13V) High Efficiency and Low-heat-generation Make the System Smaller, Thinner, and More Power-saving Pop Noise Prevention During Power Supply ON/OFF High Reliability Design by Built-in Protection Circuits - Overheat Protection - Under Voltage Protection - Output Short Protection - Output DC Voltage Protection Small Package (VQFN032V5050) Achieves Mount Area Reduction Applications Wireless Speakers, Small Active Speakers, Portable Audio Equipments, etc. Key Specifications Supply Voltage Range: 4.5V to 13V Speaker Output Power: 9W+9W (Typ) (VCC=12V, RL=8Ω, PLIMIT=0V) Speaker Output Power(PBTL): 18W (Typ) (VCC=12V, RL=4Ω, PLIMIT=0V) Total Harmonic Distortion Ratio: 0.03% (Typ) @Po=1W (VCC=11V, RL=8Ω, PLIMIT=0V) Crosstalk: 100dB (Typ) PSRR: 55dB (Typ) Output Noise Voltage: -80dBV (Typ) Standby Current: 0.1µA (Typ) Operating Current: 16mA (Typ) (No load or filter, No signal) Operating Temperature Range: -25°C to +85°C Package W(Typ) x D(Typ) x H(Max) VQFN032V5050 5.00mm x 5.00mm x 1.00mm Typical Application Circuit VQFN032V5050 Figure 1.
