When you say “the plug pack needs to be isolated”, what do you mean, specifically? 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.
The output is referred to the output Common terminal which is normally grounded. Hans 6, 1 20 The INA is a high accuracy instrumentation ampli. However, the following “LD Flasher” circuit traht I developed some years ago and which has probably been coinvented by many many other people can provide a negative supply with very few components and at low cost.
The two transistor inverter I describe will do the job you’d dtaasheet two. I might be wrong, but I don’t see a GND line anywhere in that picture. It seems I will have to get some extra component either way Gain of the INA is set by connecting a single external. Also, these chips generate a lot of switching noise.
The accuracy and temperature coefficient of these resistors are included in the ina10h1p accuracy and drift specifi- cations of the INA This must be a low-impedance con.
This simplicity has its price, and that’s that the output voltage starts to drop if you load it with more than just a few mA. This circuit is usually presented with a load of some sort in place of L1 – it may be an LED depending on voltage or a transistor base part of a following stage or a light bulb etc. Three precision op amps and laser-trimmed metal film resistors are inte- grated on a single monolithic integrated circuit. Same as above but with its own internal oscillator.
Figure 1 shows the basic connections required for operation.
ICL negative voltage converter – extremely easy to implement. What you could do is get a voltage inverter. Apart from input and output filter caps it takes 3 x R, 1 x D, 1 x c and the IC. Even Microchip makes these things, something like a TCS.

The nice thing is that you only need a few capacitors and they are available in DIP packages. There are a number of ways of making low current negative voltage supplies. The MAX shown here usesmore capacitors but makes negative and positive voltages. These are about 60c in 1 at Digikey and can be used in about every topology of smps known. Pin numbers shown dxtasheet for the TO Resistor in series with C1 will extend pulse length.
Can be eg ceramic if capacitance high enough for needs. As shown Q1 collector is driven negative below ground when Q1 turns off until energy in L1 is dissipated. If you don’t care about that and just want -5V, go ahead and do it.
Post as a guest Name. Commercial, industrial and military tem- perature range models are available. If you want a cleaner solution, you can’t power it from an Arduino only. As you can see it only needs a few components. As you’re feeding this to an analog part you should watch out for that. With a 79xx series instead of 78xx you can regulate datashete supply if required.

My ‘innovation’ was the very obvious one of using an inductor L1 as the ina101hhp. Similar for other modes such as stepup. I thought Arduino used 3V3 supply but you say you have 5V available one way or the other, so not a problem. Applications with noisy or high impedance power supplies may require decoupling capacitors close to the device pins as shown.

This could potentially be a programmer supply, LCD bias supply, -ve opamp supply etc. Sockets add to the wiring resistance which will contribute additional gain error possi- bly an unstable gain error in gains of approximately or greater.
The output is referred to the output Common terminal which. The plug pack needs to be isolated, otherwise you’re just shorting out the supplies. Sockets add to the wiring. The op amp should use little negative current if you do not drive its load negative.
