SC9153A
DESCRIPTION
The SC9153A is CMOS IC which has been designed for
electronization volume control of audio equipment,etc.
FEATURES
*Wide operating voltage range(VDD=6V ~ 12V)
*Low current comsumption .
*Attenuation can be controlled from 0dB to –66dB by 2dB/step
*Both of dual power suppliers of (+) and (-) and a single power
supply can be used.
*Be capable of controlling attenuation by means of the built-in
oscillator and the up/down terminals.

If there is possibility for excessive voltage being to the
attenuator, it is recommended to insert a protected diode as
illustrated below.
