Build 32 Watt Amplifier Circuit Using by TDA2050V. A 32 Watt per channel stereo power amplifier made using the TDA2050V monolithic integrated circuit.  32 Watt Amplifier Circuit Diagram Notes: This circuit is for a 32 Watt stereo audio power amplifier using the TDA20501. With a dual 22 Volt supply this amplifier can deliver 32W into 8 ohm loudspeakers. Moreover, the TDA 2050 delivers typically 50W music power into 4 ohm load over 1 sec at VS= 22.5V and f = 1KHz. The amplifier is cased as a Pentawatt package see pinout below: This is a power amplifier and requires 200mV RMS for full output. Voltage gain is 30.5dB with resistor values shown. Closed loop gain is set by Ratio R1/R2. Increase R2 for less gain and vice versa. Power bandwidth is 20Hz to 80KHz. R3, C3 and R6, C11 form a zobel network to prevent high frequency instability. The speaker is direct coupled, therefore no expensive large value electrolytics are needed and the bass will be crisp and clean. It is advisable to plac...

Video control and display data:  Video signal is received from TUNER, AV port(AV1,AV2,S-Video,Component) and goes to the one-chip video decoder (VCTI) which separate the R,G,B signal and passes on the signal to AD converter(AD9883) which converts 4:4:4 video format into digital and gives output to the Picture Enhancer(FLI2300).This picture enhancer improves the quality of the picture by changing the level of RGB signals. The output of this enhancer chip is fed to the deinterlacer ,which in turn goes to the Scalar (GM5221).The scalar gives the output on the LVDS cable which is connected to LCD module.  VCTi acts a micom and is responsible for video processing and audio signal processing. It accepts the RF signal and separates sound and picture from it.  Scaler is responsible for regulating the timing of signal to LCD panel and size and location of the signal. Graphic control accepts the PC(Analog RGB) and DVI-D (Digital ) signal, Scalar is responsible for regulating the t...
