产品概述 返回TOP
The CXAR4188 is a mono, high efficiency, filter-free Class-D audio amplifier and is available in WLCSP1.5x2- 12 and TQFN4x4-16 Package. The CXAR4188 is a high efficiency Class-D audio power amplifier with an integrated Class-G boost converter that enhances efficiency at low output power. It drives up to 3. 6W into an 4W speaker (1%THD+N).With 85% typical efficiency, the CXAR4188 helps extend battery life when playing audio. The built-in boost converter generates a 5.75V supply voltage for the Class-D amplifier when high output power is required. This provides a louder audio output than a stand-alone amplifier directly connected to the battery. During low audio output power periods, the boost converter deactivates and connects VBAT directly to the ClassD amplifier supply, PVDD. This improves overall efficiency. The CXAR4188 has an integrated low-pass filter to improve the RF rejection and reduce DAC out-of-band noise, increasing the signal-to-noise ratio(SNR)
