It means you have low voltage to the sensor. Before you replace it, get a simple multimeter, check the voltage on the clip for wire, you can Google which wires to test and how, then upstream on the same wire, i had the same issue. It turns out the maf was fine, the wire clip that attaches to the sensor was bad. It caused the car to rev in idle and the transmission would hit hard when going from park to drive. All this was cured with a $ 40 replacement wiring clip.
Check wiring first, i had all kinds of advice from low cost such as throttle position sensor, IAC valve and MAF replacement.
no. input impedance is low & output impedance is high
TL07x are the JFET-input operational amplifiers with low input bias and offset currents and fast slew rate. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio preamplifier applications. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip.
NOR - has two or more inputsinverter - only has one input, so that input is all inputs
Gate diffusion input is defined as the new technique of low power digital combination of circuit design. This allows reduced power consumption and delayed propagation.
