TC9235P Description
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9235P,TC9235F TC9235P/F Electronic Volume Control IC The TC9235P/F is an electronic volume control IC developed for use in audio equipment such as car stereo and portable stereo system.
TC9235P Key Features
- Attenuation can be controlled from 0dB to -78dB by up, down input
- This IC have 20dB tap for loudness circuit
- Polysilicon resistors enables low-distortion, high-performance
- Volume level remains in backup mode with low current
- Package is DIP16 and SOP16
- The 1 step/1 push volume is controlled by “L” level of UP , DN key
- If UP , DN key is input “L” continuously, volume level is changed continuously
- Timing of key input
