Apart from input and output filter caps it takes 3 x R, 1 x D, 1 x c and the IC. Use resistor between Q1b-Q2c for higher supply voltages. I should research this, but I think you can use the arduino to make a square ish wave and then use a few diodes and caps for the charge pump.

Negative voltage from Arduino? – Electrical Engineering Stack Exchange

Long time constant leads to discrete pulses. The MAX shown here usesmore capacitors but makes negative and positive voltages.

Home Questions Tags Users Unanswered. Short time constant produces a higher output frequency. When you say “the plug pack needs to be isolated”, what do you mean, specifically? These are about 60c in 1 dagasheet Digikey and can be used in about every topology of smps known. The output is referred to the output Common terminal which.


Very High Accuracy Instrumentation Amplifier

A resis- tance greater than 0. I thought Arduino used 3V3 supply but you say you have 5V available one way or the other, so not a problem. I was trying to use it on a breadboard. Russell McMahon k 9 With a 79xx series instead of 78xx you can regulate the supply if required. If you want a cleaner solution, you can’t power it from an Arduino only. Operate on 3V – 40V.

Pin numbers shown are for the Dataheet The stability and temperature datazheet of the external gain setting resistor, R Galso affects gain.

As you’re feeding this to an analog part you should watch out for that. L1 – small potted “resistor like” inductor or many others – experiment. Will not delete it though, if you find it useful nevertheless. You can use a “diode pump” driven by a square wave signal from a processor pin.

As you can see it only needs a few components. C1 polarised only to get high capacitance per size.


The nice thing is that you only need a few capacitors and they are ina10h1p in DIP packages. Low resistor values required for high gain can.

There are a number of ways of making low current negative voltage supplies. Resistor in series with C1 will extend pulse length. This could potentially be a programmer supply, LCD bias supply, -ve opamp supply etc. A smps is not usually a preferred option due to complexity.

As shown Q1 collector is driven negative below ground when Q1 turns off until energy in L1 is dissipated. Gain of the INA is set by connecting a single external.

Hans 6, 1 20 If you don’t care about that and just want -5V, go ahead and do it. But in case you have another power supply Which I think is quite usualthis solution may be very economic.
