词条 | TDA7377 |
释义 | 描述TDA7377是一种新技术AB类车用无线电放大器能够工作无论是在双桥梁或四单端配置,常用在汽车收音机上。 The TDA7377 is a new technology class AB car radio amplifier able to work either in DUAL BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with extremely reduced component count. The on-board clip detector simplifies gain compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car. 主要参数工作电压:8~18V 静态漏极电流:150mA(最大值) 输出补偿电压:150mV 极限功耗:36W 失真率:小于0.3% 反射功率:50dB 静态损耗功率:90dB 结温:-40℃~+150℃ 封装:ZIP-15 价格行情2011年2月上半月,适逢春节放假,各大电子网上,电子元器件的询价和报价次数都明显减少。功放IC TDA7377在春节期间,较少人问津,仅2个商家报出4.7元/PCS的价格,比1月份的报价下跌了0.25元/PCS。观测该型号近半年价格走势,其价格走势呈波动下降的趋势。随着电子行业旺季的到来,分析师认为后期价格会有小幅度上升,基本维持在5元左右。 |
