TDA2030 audio power amplifier circuit diagram
The TDA2030 is an audio power amplifier circuit that uses a V-type 5-pin single in-line plastic package. As shown in Figure 1, the shape of the pin can be divided into H type and V type. The integrated circuit is widely used in car stereo receivers and medium power audio equipment, and has the characteristics of small volume, large output power and small distortion. And has an internal protection circuit.
Circuit characteristics:
1. There are very few external components.
2. The output power is large, Po=18W (RL=4Ω).
3. The ultra-small package (TO-220) can increase the assembly density.
4. The boot impact is minimal.
5. Contains various protection circuits, so the work is safe and reliable. The main protection circuits are: short circuit protection, thermal protection, grounding accidental open circuit, reverse polarity of power supply (Vsmax=12V) and backlash of load bleeder voltage.
6. TDA2030A can output 16W effective power when operating at ±19V and 8Ω impedance with a minimum voltage of ±6V and ±22V, THD≤0.1%. Undoubtedly, it is a good idea to use it as a power amplifying part or a small power amplifier for a computer active speaker.
Application-Specific Integrated Circuit refers to an integrated circuit specifically designed to perform a specific computing task. It is very common to use ASIC for mining in the field of blockchain. This article will analyze the principle of ASIC mining and why it should be anti-ASIC.
For Bitcoin, mining has gone through four stages: CPU, GPU, FPGA and ASIC. GPU is naturally suitable for parallel simple operations, so the execution of SHA256 is much higher than the CPU. FPGA is a programmable hardware, because it has a certain degree of universality, so the unit price will be relatively expensive. ASIC has a large initial design investment, but the unit price will be cheaper after mass production. Therefore, if you can determine that the market size is relatively large, the use of ASIC technology will be the most cost-effective.
This is the basic principle of ASIC.
In a nutshell, mining is running complicated calculations in the search for a specific number. Whether it`s an ASIC miner or a GPU mining rig, mining hardware must run through many calculations before finding that number. In proof of work systems like Bitcoin, the first one to find that number gets a reward - at the time of writing, 12.5 Bitcoins worth around $96,850. That reward will fall to 6.25 Bitcoins in May 2020.
There are so many people and powerful computing systems trying to mine Bitcoin that miner groups form to find that number and share the profit. Even more, the faster your hardware, the more you earn. That`s why people who can afford it opt for ASIC miners because it gives them the greatest chance of earning cryptocurrency in exchange for their investment.
Each cryptocurrency has its own cryptographic hash algorithm, and ASIC miners are designed to mine using that specific algorithm. Bitcoin ASIC miners are actually designed to calculate the SHA-256 hash algorithm. In the case of Litecoin, it uses Scrypt. That means technically they could mine any other coin that`s based on the same algorithm, though typically, people who buy ASIC hardware designed for Bitcoin mine that specific digital currency.
