TPB11CQ-PC2 Datasheet 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 OdB 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. TPB11CQ-PC2 Price Notes: 1. The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time. 2. All voltage values except for differential input voltage are with respect to network ground terminal. TPB11CQ-PC2 on stock Ci forms together with the pins of T5754 and the PCB board wires a series resonance loop that suppresses the lst harmonic, hence the position of Ci on the PCB is important. Normally the best suppression is achieved when Ci is placed as close as possible to the Pins ANTl and ANT2. Aliasing and Reconstruction - If signals or noise exist in the input signal near the sample rate or its harmonics, pre-filtering may be required to ensure that the difference (lower side band or beat) frequency(ies) don't fall or alias into the pass band. Since fc/fo ratios of SCF's are reiatively quite large, this can usually be accomplished with a simple RC filter. Typically, the corner frequency of the RC filter is chosen to be 2 t0 10 times the corner frequency of the pass band. |
