TA1216AN
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA1216AN
TV-AUDIO PROCESSOR IC
TA1216AN incorporates the following : 3-channel (left, right,
woofer) signal processor circuit, I / O ports for controlling
multiplex sound demodulator IC, I / O ports for controlling
surround IC. The IC comes in a 30-pin shrink DIP plastic
package.
Using the IC facilitates volume control for channels, level
adjustment, and control of multiplex sound demodulator IC and
control of surround IC.
The I2C bus controls the functions of the IC.
