INTEGRATED CIRCUIT TA31101P, TA31101F TOSHIBA TA31101AP, TA31101AF TECHNICAL DATA The compressor and the expander of this !C are individually composed of the rectification circuit, the gain cell and the operation amplification circuit as shown in the figure below.

Rectification circuit In this circuit, the feedback-type full-wave rectification circuit is applied for improving the precision of detection, and the response characteristics (attack time, recovery time) are determined by the time constant of the smoothing capacitor of the rectifying output current connected to the E-RECT terminal and the C-RECT terminal (pin 1, pin 16) and by the time constant of the internal resistance of IC.

Gain cell (4G) This circuit is a variable gain amplifier for controlling the gain with the rectification output current of the rectification circuit. The input resistance of the input E-4Giy terminal and C-AGjjy terminal of the gain cell (pin 3, pin 14) is approximately 15kQ.. & S Inside of IC RAGINE 3. Operation amplification circuit In the compressor, since the variable gain amplifier is involved in the feedback loop of the operation amplification circuit, the oscillation is liable to be generated, however, in this circuit, since the C-Cp terminal (pin 9) for phase compensation is provided, the countermeasure can be taken against the oscillation through the external capacitor. In the compressor, for making the current gain maximum, the capacitor for decoupling the current signal is connected to the C-NF terminal (pin 12). The cut-off frequency of the compressor is determined by the product of the capacitor C19 connected to the C-NF terminal multiplied by Rp 20k0 of the internal resistance. The cut-off frequency is obtained by the expression below. aC RNE z iH om aa se 2 Ese wlOpF > 2 TA31101P -3 1994-7-15 TOSHIBA CORPORATION m9097247 OO19697 774 mf eT
