Insert USB flash driveUSB normal, replace the USB small board, everything is normal.
When the negative terminal is grounded, the maximum voltage of the positive terminal is 36V. When the negative terminal is -18V, the positive terminal is 18V. In short, the pressure difference between the positive and negative ends should not exceed 36V. Do not know tda7786c radio chip What device you are, if it is a comparator or an op amp, the different supply voltage will affect the range of output voltage, pay attention to it.
When the TV is sent to the high level power on signal (on/off), Q13 is switched on, optocoupler U5 works, Q11On, make Vcc1 produce Vcc2, send to pin 9 of TDA16888, make the PFC control circuit in the chip work, pin 8 output PFC drive signal, power switch tube QQ2 work, after the boost inductor L1 and boost diode D1, output 400V DC voltage.
A common alternative is to use other brands of audio amplifier chips, such as TDA729TDA7294. These chips work with the TDA7240Avs are similar in function and performance, so they can be replaced directly. When replacing, it is necessary to pay attention to the pin arrangement and electrical parameters of the chip to ensure the normal operation of the circuit. In addition, the TDA7240AV can be replaced with a module or board with integrated audio amplification function.
TDA7294 is a new DMOS high power audio amplifier integrated circuit from ST, it has a wide range of operating voltage, (VCC VEE) =80V; High output power (up to 100W music output power), and with silent standby function, little noise and lossReal and overheating, short circuit protection.
Chip compatible TDA7375-- 7W 7W 25W TDA7377-- 6W 6W 20W TDA7379-- 10W 10W 35W The board is suitable for car audio, HIFI audio upgrade, desktop power amplifier module, computer active speaker, home bookshelf speaker, subwoofer. The module chip is a current type power amplifier module, suitable for low resistance (2-6 ohm) speakers.
1, TDA7303 is an audio preconditioning integrated block, which has four input channels and one output channel. The following is a brief description of the TDA7303's 2-pin functions and typical circuits: 2-pin (IN1) : Input 1. Connect the audio signal source to this pin. Capacitive coupling is usually used to input the audio signal to this pin. Typical circuit connection: IN1 is connected to the audio signal source, which can be coupled by a capacitor (C1).
2, TDA7313 is a CNC audio processing chip with three pairs of inputs and four outputs. The chip is manufactured by deep submicron CMOS technology, including volume, bass, treble, channel equalization, front/back attenuation, loudness processing; In chipsets with multiple selectable gain inputs, there are fewer peripheral circuit components for better performance and reliability. All functions are programmed through the PC bus. TDA7313 is encapsulated in SOP28.
3, should be not universal supplementary information in general, the audio decoder is divided into two categories, one is for Hi-Fi listening pure audio decoder, that is, the CD player and other digital audio source equipment after two, remove the turntable (driveThe part of the rotating disk. The main function of pure audio decoder is to convert the digital audio information read into analog audio signal output for power amplification and playback. < / p > < p > 4, FM integrated circuit such as TA730TDA157LA116LA12TDA1062 models.
