You have to pull an extra wire from the sensor’s input voltage to your Arduino’s AREF pin, so you know what the actual voltage at the end of the cable is, so you can estimate the 10-90% range.

Where PSRR is equal to the power-supply-rejection-ratio specified in dB, V P is the positive voltage supply V N is the negative voltage supply V OS is the measured operational amplifier offset voltage ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal … ...

This amplifier uses a capacitively coupled chopper-amplifier architecture, with capacitive feedback instead of resistive feedback to eliminates the thermal noise, and the chopping helping to ...

And this log function voltage is valid regardless of the control voltage, Vcontrol, applied to the bases of Q1 and Q2. As one would normally note, adding emitter local feedback resistors lowers ...

The ADHV4710 op amp operates on dual supplies from ±12 to ±55 V, delivering output current of ±100 mA at the higher voltages. A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF ...

A simple linear voltage-controlled amplifier can be constructed with one op amp and two JFETs (see the figure). The amplifier can achieve an 80-dB dynamic control range with less than ±0.2% ...
