Low resistor values required for high gain can. Erion 1 5. Commercial, industrial and military tem- perature range models are available.

Add diode from output to use as a DC dattasheet. Hans 6, 1 20 The output is referred to the output Common terminal which is normally grounded.

These are about 60c in 1 at Digikey and can be used in about every topology of smps known. Long time constant leads to discrete pulses.

The output is referred to the output Common terminal which. Similar for other modes such as stepup. Will not delete it though, if you find it useful nevertheless. This circuit is usually presented with a load of some sort in place of L1 – it may be an LED depending on dwtasheet or a transistor base part of a following stage or a light bulb etc. This simplicity has its price, and that’s that dattasheet output voltage starts to drop if you load it with more than just a few mA.

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 the load.

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. 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. As shown Q1 collector is driven negative below ground when Q1 turns off until energy in L1 is dissipated.

This is the simplest switcher application I know. Resistor in series with C1 will extend pulse length. Same as above but with its own internal oscillator.

Very High Accuracy Instrumentation Amplifier

The INA is a high accuracy instrumentation ampli. My ‘innovation’ was the very obvious one of using an inductor L1 as the load. ICL negative voltage converter – extremely easy to implement. C1 polarised only to get high capacitance per size. The plug pack needs to be isolated, otherwise you’re just shorting out the supplies.

But in case you have another power supply Which I think is quite usualthis solution may be very economic. Use resistor between Q1b-Q2c for higher supply voltages. The nice thing is that you only need a few capacitors and they are available in DIP packages. A resis- tance greater than 0.


What you could do is get a voltage inverter. The MAX shown here usesmore capacitors but makes negative and positive voltages. Three precision op amps and laser-trimmed metal film resistors are inte- grated on a single monolithic integrated circuit.

The stability and temperature drift of the external gain setting resistor, R Galso affects gain. Also, these chips generate a lot of switching noise. Here is an example of a MC in an inverting supply – positive to negative.

The two transistor inverter I describe will do the job you’d need two.

Operate on 3V – 40V. These chips ‘invert’ the power supply from Vout to -Vout. Applications with noisy or high impedance.

Even Microchip makes these things, something like a TCS. Pin numbers shown are for the TO Sign up using Facebook.
