TA8776N surround sound analog integrated circuit

Published:2011/5/6 4:04:00 Author:TaoXi | Keyword: surround sound, analog

TA8776N surround sound analog integrated circuit

The TA8776N is designed as one kind of surround sound analog integrated circuit that is produced by the TOSHIBA company, and it can be used in the TV audio system and home theater sound system. 1. TA8776N in-circuit block diagram and the pin functions The TA8776N's manifold-circuit is controlled by the I2C-bus, and it can control the audio volume, increase the high pitch, increase the low pitch, adjust the left and right channels, surround sound switch, bass switch and control the volume. The in-circuit block diagram is as shown in figure 1. This IC is in the 30-pin double-row type package, the pin functions and data is as shown in table 1. Figure 1 The in-circuit block diagram Table 1 The pinfunctionsanddata of the TA8776N 2. The typical application circuitof the TA8776N The typical application circuitof the TA8776N is as shown in figure 2. 3. The circuit working process (1)Volume control. The volume control signal of the microprocessor is processed by the TA8776, and forms the DC voltage to control the internal attenuator. Higher the pin (27)'s voltage is, louder the volume is. (2)Left and right balance control. Left and right balance control signals of the microprocessor form the DC voltage in pin-26. The control law is same to above. (3)High, low bass control. Bass boost control signal of the microprocessor forms the DC voltage in pin-11. High pitch boost control signal forms the DC voltage in pin-18.4. Troubleshooting Tips (View)
