LM358 is the core two-stage operational amplifier, which can amplify DC weak signals, such as DC voltage signals, DC pulse signals, can amplify signals of millivolts or even weaker, and has two potentiometers, respectively for the first stage and The second stage performs single-stage magnification adjustment, but the total magnification is the product of the two-stage multiple, so the magnification will be adjusted to a large extent.
If the first level is adjusted to 20 times magnification, then if the second level is adjusted to 100 times, then the total magnification is 2000 times.
Note: the default of this LM358 Amplifier is 1000 times.
Parameters:
1. Power supply voltage: 3.5-24V DC power supply
2. Current output: maximum 15-20MA (non-linear)
3. Voltage output: output = input voltage signal * magnification
4. Magnification: Total multiple = first multiple multiple * second multiple multiple
5. Board size: length 45.3mm width 16.2mm
6. The two potentiometers on the board are rotated counterclockwise to increase the multiple.
Package included:
4* LM358 Weak Signal Amplifier Boards

Excellent Op AmpsThe LM358 has been the industry standard since the 1970's these are excellent dual opamps for a wide range of uses.Im using 2 of these in my home built 15 band graphic equalizer, one for the line in and one for the line out, to boost the audio levels, also using one of these to boost the levels of the LM3916 VU meter LED outputs so i can calibrate them to 0dBThese are great performing opamps, i highly recommend them.

Buon prodotto, ma sprovvisto di qualsiasi indicazione tecnica. Per avere qualche informazione sul prodotto, bisogna contattare il venditore.

Sono in corso l' analisi e le misure di rito. Al momento un segnale ad onda quadra ridotta ad ,001 volt cioè 1mV non è misurato da oscilloscopio occorre cioè inserire un pre davanti al modulo e moltiplicare per 10 oltre a presentare una resistenza di ingresso molto elevata senza dubbio superiore ai 10 Mega dichiarati. In conclusione è possibile utilizzare il modulo ma occorre adeguarlo alla finalità. Buon lavoro.
