This IC has designed with low-power, bandwidth and high stability for operating with single power supply over extensive voltage ranges. The connection of LEDs count can also be improved up to 25. We only need to connect a measuring or processing circuit to the output of A1 to indicate the temperature or perform other automatic control. According to the value Av=-10 given in the figure, the input resistance of this circuit is Ri. Because the in-phase terminals of each op amp are grounded through the R junction of R1~R4 and R5 and BG, each op amp outputs a low level; When AN1 is pressed, R6 and R1 divide voltage (because the voltage of C cannot be abruptly changed, BG has not been turned on), so that the non-inverting input terminal of the operational amplifier IC-1 generates a certain voltage. These electronic voltage amplifiers are available in high gain with differential input as well as a single output. Turbo Bass with IC LM324 Circuit Diagram. and 3 OP-amp is applied to parallel together.

The pin configuration of the IC LM324 is shown below, and the function of each pin of this IC is discussed below. When the feedback resistance of the op amp is removed, or when the feedback resistance tends to infinity (that is, the open-loop state), in theory, the open-loop magnification of the op amp is also infinite (in fact, it is very large. For example, the open-loop amplification of the LM324 op amp is 100dB, or 100,000 times). The center frequency of this active band-pass filter is , and the voltage gain Ao=B3/2B1 at the center frequency fo, .3dB bandwidth B=1/(п*R3*C) can also be based on the Q, fo, Ao values determined by the design, to find the component parameter values of the band-pass filter. 3. Non-inverting AC Amplifier Circuit. The temperature coefficient of the emitter junction voltage of a silicon transistor is about -2.5mV/°C, that is, every time the temperature rises by 1 degree, the emitter junction voltage will drop by 2.5mV. When static, the voltage at the output of A1 is 1/2V+, so the output of the op amp A2-A4 is also 1/2V+. This circuit uses a LM324 IC, whose pin diagram has been shown in the image below: [[wysiwyg_imageupload:7744:]] This Op amp comparator circuit project uses opamp as comparator.
