Электронный регулятор громкости
The TC9153/54AP is an optimum C2M0S IС which has been designed for electronization of volume control of audio equipment, ect. with the following features.
- Attenuation can be controlled from OdB to -66dB by 2dB/step.
- 2 channels have been built In.
- Both of dual power supplies of (+) and (-) and a
single power supply can be used.
- The TC9153AP is capable of controlling attenuation by means of the built-in oscillator and the up/down terminals.
- The TC9154AP is capable of optionally controlling
attenuation and channel balance when specified
signals are externally applied to the data, clock
and strobe input terminals.
- Being in C2-M0S structure, the operating voltage
range is wide and current consumption is low. Vdd=6 ~ 12(V) (Backup is possible up to 4V)
