Class-D Speaker Amplifier for Digital Input - BD5452AMUV

BD5452AMUV is a Class D Speaker Amplifier designedfor Flat-panel TVs in particular for space-saving andlow-power consumption, delivers an output power of15W+15W. This IC employs state-of-the-art Bipolar,CMOS, and DMOS (BCD) process technology. With thistechnology, the IC can achieve high efficiency. Inaddition, the IC is packaged in a compact reverse heatradiation type power package to achieve low powerconsumption and low heat generation and eliminatesnecessity of external heat-sink up to a total output powerof 30W. This product satisfies both needs for drasticdownsizing, low-profile structures and many function,high quality playback of sound system.

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

  • ・ This IC has one system of digital audio interface.(I2S format, SDATA: 16 / 20 / 24bit, LRCLK: 32kHz / 44.1kHz / 48kHz, BCLK: 64fs(fixed), MCLK: 256fs / 512fs)
    ・ Low supply current at RESET mode.
    ・ The decrease in sound quality because of the change of the power supply voltage is prevented with the feedback circuitry of the output. In addition, a low noise and low distortion are achieved.
    ・ Eliminate large electrolytic-capacitors for high performance of Power Supply Rejection.
    ・ Power Limit Function. (at RL =8 , 10W /5W /OFF)
    ・ Available for Monaural mode.
    ・ Within the wide range of the power supply voltage, it is possible to operate in a single power supply. (10 to 18V)
    ・ It contributes to miniaturizing, making to the thin type, and the power saving of the system by high efficiency and low heat.
    ・ Eliminates pop noise generated when the power supply goes on/off, or when the power supply is suddenly shut off. High quality muting performance is realized by using the soft-muting technology.
    ・ This IC is a highly reliable design to which it has various protection functions. (High temperature protection, under voltage protection, Output short protection, Output DC voltage protection and Clock stop protection, (MCLK, BCLK, LRCLK)
    ・ Small package (VQFN032V5050 package) contributes to reduction of PCB area.
