There are some basic questions you should ask before looking for a suitable op amp.
（1）What is the input signal going to look like?
（2）Current-input or voltage-input?
（3）What is the expected operating frequency range? Maximum range?
（4）What amplitude is needed? (Typical and maximum values.)
（5）What’s the impedance of the circuit it’s going into?
（6）What is an acceptable output signal going to look like?
（7）What is the expected range of frequencies the output signal might cover?
（8）What is the expected amplitude range?
（9）Will the op-amp be driving another device? If so, how much power will be needed?
（10）How accurate or precise does the op-amp need to be?
The operating environment:
What supply voltage(s) are available?
Is there a physical size limitation? You may need to make a list of packages of an acceptable size.
What is your operating temperature range? Figure out a Max, Min, and Typical.
Look at how the temperature affects your most critical parameters using the graphs in the datasheet. If the information you need is missing, you can contact the company or set it aside and move on to another spec that is more thorough.
Hi y'all, today's blog is about the CR2430 battery.
First, let's get to know what is coin batteries:
Coin batteries, commonly known as button cells. A watch battery or button cell is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high — resembling a button. Stainless steel usually forms the bottom body and positive terminal of the cell. An insulated top cap is a negative terminal.
Coin batteries are commonly used in garage door openers, medical devices, watches, remote controls and greeting cards with sound. Do not leave these devices readily available and make sure children are supervised when in contact with them so that access to coin batteries can be prevented.
Hey guys, welcome back to this blog, today i'll introduce the difference between LM317 and LM350, stay tuned fellas!
LM317 is an adjustable three-terminal regulator. The world's major IC manufacturers have similar products to choose from. Therefore, LM317 is a widely used series of integrated voltage regulators, and can be used as a voltage regulator circuit in a DC regulated power supply.
Hey guys, welcome to this blog. Today is another comparison article on electronic components, we will focus on NE5532 and its similar components: OPA2134, TL072 and NE5534. So off we go!
NE5532 vs OPA2134
The NE5532 is a Bipolar Input op-amp and the OPA2134 is a Fet Input op-amp.
Although many people claim NE5532 as an old component and try to find a new one to take its place, the NE5532 is still good enough for most applications. Plenty of new audio equipment still uses old op-amps such as the NE5532 and TL072 because anything better is overkill and not cost-effective.
If you can use a bipolar OP, the NE5532 is usually the better choice than a JFET OPA2132 / OPA2134. The OPA2134 is more a better replacement for the TL072 when you need a FET type. This may be the case with low-frequency filters.
Hey guys, if you are an electronic DIY lover, you will always find a lot of similar or interchangeable components, which have subtle differences in the specs or features, therefore lead to the wrong application, 74HC595 and its similar components is an example I'm going to mention today.
74HC595 and 74HC164, 74LS595 and MCP23017, except for the last one, the former three ICs are shift registers that can drive LEDs, especially 74HC595, it can drive LEDs directly, those components are alike in some way and have their own distinguishing features as well.
So let's explore these four ICs specifications and compare them to see what are their differences.
74HC595 VS 74LS595
74LS595 is TTL based, fast, uses more power and is older.
74HC595 is CMOS based, fast, uses less power and is the most up-to-date version.
