型號：KA2284（AC/DC電源IC）

封裝:ZIP-9

概述:

The KA2284 is a monolithic integrated circuit designed for 5-dot LED level meter drivers with a built-in rectifying amplifier. It is suitable for AC/DC level meters such as VU meters or signal meters.

特性:

1、High gain rectifying amplifier included(Gv=26dB)

2、Low radiation noise when LED turns on

3、logarithmic indicator for 5-dot LED of bar type

4、Constant current output( 15mA)

5、Wide operating supply voltage(3.5V~11V)

6、Not necessary diode or transistor for ALC

7、Minimum number of external parts required
