Tool/software:
Hi E2E experts,
I am a bit confused while looking at the datasheet because some of the specifications lack detailed explanations. In the Electrical Characteristics table, what does "Open-loop gain" mean? I found a frequency response curve that seems to match this specification.
Here are my questions:
1. On the Y-axis, does VPWM refer to the waveform output from the pin PWM or the waveform at the sensor input pin IS1?
2. "Gain" here is defined as VPWM_average/(VICOMP1, VICOMP2), but shouldn’t its reciprocal represent the Open-loop gain?
3. What does the frequency on the X-axis specifically refer to? Is it the frequency of the input signal? If so, the Electrical Characteristics indicate that when the input signal is 7.8kHz, the gain is 24/32dB, right?
Looking forward for your reply. Thank you very much!
