KA22241
DUAL EQUALIZER AMPLIFIER WITH ALC
DESCRIPTION
The UTC KA22241 is a monolithic integrated circuit, consisting of dual equalizer amplifier with ALC, and it is suitable for stereo radio cassette tape recorders.
FEATURES
* Dual equalizer amplifier with built-in ALC circuit
* Low noise VNI=1.0μV(Typical) * High open loop voltage gain: Gv=80dB(Typical)
* Good ALC response balance between channels
* Not necessary the input coupling capacitor
* Not necessary the diode or transistor for ALC
* Built in power supply muting circuit
* Minimum number of external parts required
BA3308-S14-R/KA22241G-S14-R
BA3308-S14-R/KA22241G-S14-R都是UTC品牌的IC,这两个型号可以替换使用,是带ALC的双前置放大器,线性集成电路,封装是SOP-14, 一盘是2500pcs。
说明
UTC BA3308设计为具有双前置放大器IC,内置ALC电路,用于立体声放大。这个前置放大器具有高增益和低失真。内置整流器对于ALC电路意味着良好的信道平衡,和大的动态范围,可以通过添加一个外部时间,来构建恒定电路。
特征
*宽工作电源电压范围
(VCC=4.5V~14V)
*打开静音电路电源,避免产生“爆裂”噪音。
*不需要输入耦合电容器
*高增益(GVO=80dB)和低噪声(VNIN=1µVrms)
*低失真(THD=0.1%)
*内置ALC整流二极管,具有良好的ALC通道平衡
