1. There is no difference between LM224 and LM324 in principle. LM224 has better performance than LM324, especially in the operating temperature range. The LM224 is an industrial grade IC with an operating temperature range of -40 degrees to 85 degrees, and the LM324 has an operating temperature range of 0 degrees to 70 degrees.
2, belongs to the industrial grade chip. The LM224 is a quad-amp integrated circuit in a 14-pin dual-in-line plastic (ceramic) package. itInternal contains four groups of exactly the same form of operational amplifiers, in addition to the power sharing, the four groups of operational amplifiers are independent of each other. Each group of operational amplifiers has 5 leading pins, which are industrial grade chips.
3, LM224 and LM258 are industrial grade devices, and their indicators are the same (according to TI's data manual), in fact, they are the same series of four-channel and dual-channel models of the op amp, with two LM258 instead of a LM324 is the best choice.
4, such as the general type of LM224, most of the input impedance value can not be found, but you canPCF7935. Volkswagen Santana Zhijun car key ID44 anti-theft chip ceramic PCF7935. Can not be copied, 7935 or supermodel chip can be used to generate Volkswagen 44 car match. Tried many times, that is, the anti-theft light is not extinguished, and occasionally the car can be carried, but the anti-theft light is still not extinguished.
2, what is the use of ceramic substrate, ceramic substrate refers to the copper foil at high temperature directly bonded to alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate surface (single or double) on the special process board. Let's see what the ceramic substrate is used for.
3, packaging classification: metal, ceramic and plastic three categories, plastic substrate with its high proportion of use dominates, especially in advanced packaging, plastic substrate fine wiring and multi-layer packaging capabilities are favored.
1, LM224 and LM258 are industrial grade devices, and their indicators are the same (according to TI's data manual), in fact, they are the same series of four-channel and dual-channel models of the op amp, with two LM258 is the best choice to replace a LM324.
2, the working principle of the lm224 chip is to run by feeling the size of the current. According to the relevant public information, the lm224 chip will start to work when the current size reaches a certain amount.
3, the chip is mainly a temperature problem, the original commercial grade code is C: 0~70℃; The industrial grade code is I: -20~85℃, and some later modified to -40~85℃; The military grade code is M: -55~150℃. The automotive grade is an extension of the industrial grade.
1. LM224 can be directly replaced by LM324. All LM12LM22LM324 pins have the same performance and can be directly replaced.
2, LM324N 3 prefix represents civilian products with N round cap LM224N 2 prefix represents industrial grade with J ceramic seal LM124J 1 prefix represents military belt N plastic seal HYNIX More information viewPackage: DP represents DIP package DG represents SOP package DT represents TSOP package.
3, from the patch package such as LTC1051, to the width of IDT DIP, PLCC, etc., the package form directly determines the electrical performance and stability of the product. NS series, such as LM324N/LM224N/LM124J, distinguish civilian, industrial and military grade products through grade identification.
can be replaced, their function and pin are exactly the same. However, the LM224 is an industrial device with an operating temperature range of -25 ° C to 85 ° C, while the LM324 is a commercial device with a operating temperature range of 0 ° C to 70 ° C, and there is no other difference.
There is no difference between LM224 and LM324 in principle, and LM224 has better performance than LM324, especially in the operating temperature range. The LM224 is an industrial grade IC with an operating temperature range of -40 degrees to 85 degrees, and the LM324 has an operating temperature range of 0 degrees to 85 degreesSeventy degrees.
LM224 can be directly replaced by LM324. All LM12LM22LM324 pins have the same performance and can be directly replaced.
