本文辑录30种在随身听中最新使用的IC和部分最常用IC的特性、功能,供电子爱好者、维修人员参考。 1.AN7081K 单片立体声放音机电路,含双前置、双功放、电子音量控制和马达稳速电路。一片ANT081K就可组成一部完整的立体声放音机。V_(cc)=1.8～6V,采用24脚双列直插封装。当V_(cc)=3V,R_L=32Ω时,输出功率P_0=30mW×2。 2.AN7082K 单片立体声放音机电路。其功能、内电路、V_(cc)范围与AN7081K相同。当V_(cc)=3V,R_L=32Ω时,输出功率P_0=20mW×2。AN7082K采用22脚双列直插封装,引脚功能与AN7081K不一一对应,不能直接代换。
This article is a collection of 30 kinds of IC and some of the most commonly used IC in the Walkman in the most commonly used features, functions, for electronic enthusiasts, maintenance personnel reference. 1.AN7081K monolithic stereo player circuit, including dual front, bi-amp, electronic volume control and motor speed circuit. An ANT081K can form a complete stereo player. V_ (cc) = 1.8 ~ 6V, 24-pin dual in-line package. When V_ (cc) = 3V, R_L = 32Ω, the output power P_0 = 30mW × 2. 2.AN7082K monolithic stereo player circuit. Its function, internal circuit, V_ (cc) range and AN7081K the same. When V_ (cc) = 3V, R_L = 32Ω, output power P_0 = 20mW × 2. AN7082K using 22-pin dual in-line package, pin function and AN7081K not one to one correspondence, can not be directly replaced.
