TA7176AP为电视伴音系统集成电路,是无锡742厂引进日本东芝公司技术生产的电视专用系列集成电路,内含伴音中频限幅放大、有源低通滤波、差分峰值鉴频、电子音量控制、音频电压前置放大等电路,能完成彩色和黑白电视机中除音频功率放大之外的全部伴音电路功能。外接元件少,调整简单,功放电路外接,性能稳定可靠,设计灵活。但与μPC1353C、AN355、AN5250等集成电路相比,功能还不够完整。
TA7176AP TV audio system integrated circuit, is the introduction of Toshiba factory in Wuxi 742 plant for television special series of integrated circuits, including audio intermediate frequency limiting amplification, active low-pass filter, differential peak frequency, electronic volume control, audio voltage Preamplifier and other circuits, to complete the color and black and white TV in addition to the audio power amplifier outside all the audio circuit functions. Less external components, simple adjustment, external power amplifier circuit, stable and reliable performance, flexible design. However, with μPC1353C, AN355, AN5250 and other integrated circuits, the function is not complete enough.
