Datasheet Middle Power Class-D Speaker Amplifier series 15W+15W Class D Speaker Amplifier for Digital Input BD5452AMUV General Description Key Specifications BD5452AMUV is a Class D Speaker Amplifier designed Supply voltage: 10V to 18V for Flat-panel TVs in particular for space-saving and Speaker output power: 15W+15W low-power consumption, delivers an output power of (VCC=16V, RL=8 , Power Limit=Off) 15W+15W. This IC employs state-of-the-art Bipolar, Total harmonic distortion: 0.08 (Po=4.5W) CMOS, and DMOS (BCD) process technology. With this Crosstalk: 80dB(Typ.) technology, the IC can achieve high efficiency. In PSRR: 65dB(Typ.) addition, the IC is packaged in a compact reverse heat Output noise voltage: 100 Vrms(Typ.) radiation type power package to achieve low power Standby current: 100A (Typ.) consumption and low heat generation and eliminates Operating temperature range: -25 to +85 necessity of external heat-sink up to a total output power of 30W. This product satisfies both needs for drastic Package(s) W(Typ.) x D(Typ.) x H(Max.) downsizing, low-profile structures and many function, VQFN032V5050 5.00mm x 5.00mm x 1.00mm high quality playback of sound system. Features 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. VQFN032V5050 Within the wide range of the power supply voltage, it is possible to operate in a single power supply. (10 to 18V) Typical Application Circuit It contributes to miniaturizing, making to the thin type, and the power saving of the system by high efficiency SP ch1 SP ch2 and low heat. (Lch) (Rch) 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 UTOP1 NT1OU P2TUO T2OUN stop protection, (MCLK, BCLK, LRCLK) Small package (VQFN032V5050 package) M TRS UMT PLIM LMPI RRE DAS RCL LCB KCL X E 0T 1T OR TA KL K contributes to reduction of PCB area. Applications noc- Flat Panel TVs (LCD, Plasma), Home Audio, Desktop Digtial Audio Source PC, Amusement equipments, Electronic Music equipments, etc. Figure 1.
