آمپلی فایر سیگنال LM358 AC Signal Amplifier:

آمپلی فایر سیگنال LM358 AC Signal Amplifier، یک ماژول آمپلی فایر عمومی سیگنال تک کانال با چیپ نام آشنای LM358 است، گین آن قابل تنظیم و ولتاژ تغذیه 2 تا 14 ولت می باشد.

Description:

The two stages operational amplifier with LM358 chip as core. It can amplify the weak signal of AC. Such as sine wave signals or positive and negative pulse signals. It can also amplify the millivolt signal even weaker signals.
There are two potentiometers. They adjust the magnification of the first and second stages respectively. The total magnification is the product of two stages’ magnification. So the magnification will be adjusted to a great extent. (If the first stage is magnified to 20 times and the second level is magnified to 100 times, then the total magnification is 2000 times)

Specification:

Working Voltage: Positive and negative DC 2-14V
Current output: Maximum 15-20mA
Size: 42mm * 22mm (L*H)
The two potentiometer on the board counter anticlockwise rotation is adjusted multiple times.
