    Converter DC/DC - Am i using this circuit correctly?

    Converter DC/DC - HELP https://www.murata-ps.com/data/power/ncl/tdc_pwr13xx.pdf I am looking for a voltage booster circuit that will give me a constant Vout of +12V and -12V when Vin ranges from 10.8v to 13.8v. I thought I found what i wanted from farnell. The technical specs of this module...

    Inclionometer question-must the voltage of B be reverse of A

    Inclionometer question.. I have a very newbie question, pls pardon me ... I have an inclionometer that accepts voltage input of +12V for A and -12V for B. My question is, must the voltage of B be the exact the reverse of A? Can B be -12.10V and A be +12.58V? Will it affect the...

    How to convert voltage -5V to +5V to a range of 0-5v

    U are right, the voltage divder should be 2R:R, based on the calculation. So, i use the following resistor values, Rg = 10K, Rp = 20K, Rq = 20K, Rf = 10K, Vp = 5V Vcc = 5V (LM358) Vcc- = 0V With the above calculation, i should get the following Vr based on the Vq value. Vq = 0, Vr = 2.5v...

    How to convert voltage -5V to +5V to a range of 0-5v

    I have an inclinometer that outputs a range of -5 to +5v. The output of the inclinometer will be fed to my PIC that can only takes in positive voltage in the range of 0-5V. I have the following circuit as shown in the attachment. The gain of the op amp is --0.5 in this case. When I put Vin...
