Seems that you want to use the UNO as a source, making my answer obsolete. Figure 1 shows the basic connections required for operation.

Very High Accuracy Instrumentation Amplifier

Low resistor values required for high gain can.

The two transistor inverter I describe will do the job you’d need two. Also, these chips generate a lot of switching noise. Pin numbers shown are for the TO As you can see it only needs a few components.

L1 – small potted “resistor like” inductor or many others – experiment. The op amp should use little negative current if you do not drive its load negative. Here is an example of a MC in an inverting supply – positive to negative. Sockets add to the wiring. What you could do is get a voltage inverter. ICL negative vatasheet converter – extremely easy to implement. It seems I will have to get some extra component either way Add diode from output to use as a DC supply.

The MAX shown here usesmore capacitors but makes negative and positive voltages. Sign up or log in Sign up using Google. There are many variants on this IC including some that use 0.

There are a number of ways of making low current negative voltage supplies. Sign up daasheet Facebook. Can be eg ceramic if capacitance high enough for needs. Home Questions Tags Users Unanswered. These are about 60c in 1 at Digikey and can be used in about every topology of smps known.

The accuracy and temperature coefficient of these resistors are ina101yp in the gain accuracy and drift specifi- cations of the INA Post as a guest Name. It might be bad because it takes up more room, etc.

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 datashset. Not vastly efficient by modern standards. Gain of the INA is set by connecting a single external. These are on-chip metal film resistors which are laser trimmed to accurate absolute val- ues.

Pin numbers shown are for the TO metal package. This is the simplest switcher application I know.

This must be a low-impedance con- ratasheet to assure good common-mode rejection. Note that these power supplies can’t supply much more than a few tens of mA this one can do 20mA. You can use a “diode pump” driven by a square wave signal from a processor pin.

The output is referred to the output Common terminal which. I thought Arduino used 3V3 supply but you say you have 5V available one way or the other, so not a problem.

As shown Q1 collector is driven negative below ground when Q1 turns off until energy in L1 is dissipated. The plug pack needs to be isolated, otherwise you’re just shorting out the supplies. Resistor in series with C1 will extend pulse length. If you have only 3V3 available your options are more limited. This provides a pulse of current into L1 when Q1 is on and when Q1 turns off L1 “flys back” and delivers whatever voltage is required to dump the energy from L1 into catasheet load.

Negative voltage from Arduino? These chips ‘invert’ the power supply from Vout to -Vout. The stability and temperature drift of the external gain. As shown here it is an LED flasher but if neither LED is used and a diode is connected at the collector of Q1 top of L1 negative voltage will be produced.

Commercial, industrial and military tem. Email Required, but never shown. Apart from input and output filter caps it takes 3 x R, 1 x D, 1 x c and the IC.
