CXAB4114是一个五瓦封装的单片集成电路，用作AB类音频放大器。由于其高功率能力，CXAB4114能够在THD=10%V S=±8V，f=1kHz时向4欧姆负载提供高达33W的真有效值功率，在THD=10%，VS=±2V，f=1kHz时向8欧姆负载提供高达30W的真有效值功率。
此外，CXAB4114在VS=22V，f=1khz的情况下，在1秒的时间内将典型的50W音乐功率传输到4欧姆负载中。
高功率，极低的谐波和交叉失真（THD=0.05%典型值，在VS=±2V，PO=0.1至15W，RL=8ohm，f=100Hz至15kHz）使该设备最适合于高保真和高端电视机
高输出功率（50W音乐功率IEC 268.3规则）
高工作电源电压（44V）
单一或分体式供应操作
非常低的失真

产品概述 返回TOP
The CXAB4114 is a monolithic integrated circuit in a Pentawatt package, intended for use as an audio class-AB audio amplifier.
Thanks to its high power capability the CXAB4114 is able to provide up to 33W true RMS power into a 4 ohm load at THD = 10%V S = ±18V, f = 1kHz and up to 30W into an 8 ohm load at THD = 10%, VS = ±22V, f = 1kHz.
Moreover, the CXAB4114 delivers typically 50W music power into a 4 ohm load over 1 sec at VS = 22V, f = 1 kHz.
The high power and very low harmonic and crossover distortion (THD = 0.05% typ, at VS = ±22V, PO = 0.1 to 15W, RL= 8ohm, f = 100 Hz to 15 kHz) make the device most suitable for both hi-fi and high-end TV sets
