Table 13 The pin functions and data of the TDA4660 and TDA4660V2
1.Features
The TDA4857's line & field oscillator can automatically changes the line and field oscillation frequency by the input horizontal and vertical sync signal. The free oscillation frequency of the line oscillator is 31.45 khz, the line frequency operating range is 50 to 130kHz, the field frequency operating range is 50 to 60Hz. The IC's field excitation signal output is the differential output mode, this mode can outputs the descent field ramp and the ascent field ramp to drive the DC coupling field output circuit. This circuit also has the soft start function, the X-ray protection function and the +B switching power supply control function.etc. The integrated block internal box circuit is as shown in figure 13.

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)
