Another approach is to use potentiometers to vary the value of the resistors that set the gain of the amplifier. Consider the circuit schematic presented in Figure 1. Figure 1. Voltage control using a ...

the choice of which topology to use is usually between a non-inverting amplifier and an inverting amplifier (Figure 1). Both circuits utilize a single feedback resistor and single gain resistor.

void calculate_non_inverting_gain(); // Non-inverting amplifier gain calculation ...

This is the analog circuit cookbook for a non-inverting comparator with hysteresis: Non-Inverting Comparator with Hysteresis Circuit. The cookbook uses a TLV7041 with a pull-up resistor, but you can ...

When working with op-amps, is important to consider both the input and output voltage range of the amplifier. The OPA211 inputs must remain more than 2V away from the negative Supply (V-). See OPA211, ...

void calculate_low_pass_filter(); // Low-pass filter cutoff frequency calculation void calculate_high_pass_filter(); // High-pass filter cutoff frequency calculation // Helper function declarations ...

In module 4 you will learn the theory and practical application of amplifiers and circuit noise. You will review how gain is calculated in inverting, non-inverting, summing, differential, and ...
