Package : DIP 16 Pin Type
Manufacturers : Silan Microelectronics
See the preview image and the PDF file for more information.
The SC9153 is CMOS IC which has been designed for electronization volume control of audio equipment,etc.
1. Wide operating voltage range(VDD=6V ~ 12V)
2. Low current comsumption.
3. Attenuation can be controlled from 0dB to –66dB by 2dB/step
4. Both of dual power suppliers of (+) and (-) and a single power supply can be used.
5. Be capable of controlling attenuation by means of the builtin oscillator and the up/down terminals
Absolute maximum ratings
1. Supply Voltage(Pin 16) : VDD = 13.0 V
2. Input/Output Voltage : VIN = VSS0.3V ~ VDD+0.3V V
3. Power Dissipation : PD = 150 mW
4. Operating Temperature : Topr = 30 ~ +75 °C
5. Storage Temperature : Tstg = 55 ~ +125 °C
