FreePCB Software

Software with open source software, specializing in professional development and editing of printed circuit boards.
FreePCB program is fairly well known in Russia, but she won the main popularity in the U.S. and in India. This editor is very easy to learn and at the same time able to withstand the high demands for quality professionals PCB design. The program allows you to get results in a larger format Gerber (topology files) format and Excellon (files for drilling). These data is sufficient to order the production of boards in offices specialize in this. Besides software package supports up to 16 layers, you can work with both inch and metric units. PCB size can be up to 1524x1524 mm. Editor uses the library buildings from companies IPC, PCB Matrix and Design International. It is possible to import and export a netlist in PADS-PCB. In recent version adds verification of compliance with design rules and AutoSave results. For lovers of the printed circuit board at home, FreePCB represents the result separately for each layer in a graphical format PNG. This editor uses only hand-wiring boards, but can work in tandem with third-party avtotrassirovschikom FreeRouting. Among the few drawbacks are the lack of print option in the program.

FreePCB editor boards designed to work with the editor of schemes TinyCAD . In addition, the live broadcast will be available from the simulator netlist LTspice program FreePCB. There is an opportunity on the basis of a full and free programs to collect system through design containing simulator, editor of electrical circuits and printed circuit boards breeder.
FreePCB program written entirely in English and has no localization system. However, amateur radio enthusiast Valentin Volodin was made ​​very decent translation of manuals, which can be found on this page . There is also stored online description of the software package FreePCB buildings in Russian.
The entire software package FreePCB from the first to the last line was written by a single man named Alan Wright (Allan Wright). Talented programmer living in the United States. In addition to electronics, despite his advanced age, Alan loves to travel, skiing, and even self-piloting his own plane RV-4. To get the necessary information on the program enough to ask a question on our site.
FreePCB works on all operating systems Microsoft Windows, including the latest - Windows 7. It can be run on Linux and Macintosh using the Wine.
Distribution of the program: Freeware

One Chip AM/FM Radio with Audio Power Amplifier

Description: The integrated circuit TDA1083 includes, with exception  of the FM front end, a complete AM-/FM-radio-circuit  with audio power amplifier. An internal Z-diode  stabilizes the supply voltage at VS 13 V, which allows  with the aid of a resistor and a rectifier, the circuit to be  driven by a higher external supply voltage. Features: Large supply voltage range VS = 3 to 12 V High AM-Sensitivity Limiting threshold voltage Vi = 50 V Audio output power P0 = 0.7 W AFC-connection for VHF-tuner AM-FM switching without high frequency voltages Applications: AM-/FM- and audio-amplifier Circuit Diagram: Circuit diagram for One Chip AM/FM Radio with Audio Power Amplifier Datasheet for TDA1083:   Download

2 x 15 W stereo Bridge Tied Load (BTL) audio amplifier

General description: The TDA8946J is a dual-channel audio power amplifier with an output power of 2 × 15 W at an 8 Ω load and a 18 V supply. The circuit contains two Bridge Tied Load (BTL) amplifiers with an all-NPN output stage and standby/mute logic. The TDA8946J comes in a 17-pin DIL-bent-SIL (DBS) power package. The TDA8946J is printed-circuit board (PCB) compatible with all other types in the TDA894x family. One PCB footprint accommodates both the mono and the stereo products. Features: Few external components Fixed gain Standby and mute mode No on/off switching plops Low standby current High supply voltage ripple rejection Outputs short-circuit protected to ground, supply and across the load Thermally protected Printed-circuit board compatible Circuit Diagram: Circuit Diagram for 2 x 15 W stereo Bridge Tied Load (BTL) audio amplifier PCB layout: PCB layout TDA8946 Datasheet for TDA8946J:   Download

200W Hybrid Audio Amplifier Circuit

200W Hybrid Audio Amplifier Circuit - c onnecting two TDA2030 thru cheap power transistors we can create a amplifier wich can deliver a higher power. With the components value from the schematic the total amplifier gain is 32 dB. The speaker can be 2 ohm instead of 4 ohm if we use the TIP transistors. TDA 2030 is produced by SGS Ates and is a complete audio amplifier. AB class of the final amplifier cand deliver up to 14W on 4 ohm at a +-14V power supply. With a proper designed power supply this audio amplifier can output 200W. Active components: IC1, Ic2 TDA 2030 T1, T3 = BD 250, TIP 36 T2,T4 = BD 249, TIP 35 D1 … D4 = 1N4001 200W Hybrid Audio Amplifier Circuit
