Always remember that even the single power supply OP AMP entries must be biased in order to work within the linear zone.

I did following modification in given circuit to make it for 12V battery.

I am tired debugging the above circuit.

LM308 Datasheet PDF

The diagram below shows that my chip uses the input stage from the ml308 LM blue. In any case, great article. LMA has its performance guaranteed over a b 25 C to. LM Question No still there is problem: I used a metallurgical microscope for my die photos, but you can use even a basic middle-school microscope to see many of the chip features.


Since both transistors have the same emitter lm38 and base voltage, they source the same current, so the current on the right matches the reference current on the left.

If you’ve adtasheet electronics, you’ve probably seen a diagram of an NPN transistor like the one below, showing the collector Cbase Band emitter E of the transistor. It’s a big difference. If the two inputs are equal, the current is split equally between the two branches.

Instead it matches the Motorola datasheet. Dec 248: I also tried to put 3.

LM Datasheet, PDF – Alldatasheet

This image shows some of them: After adding the diodes, have you lowered the series resistance? While the chip seems incomprehensible at first, close examination reveals the different components and their connections.

With simple feedback circuits, you can use an op amp as an amplifier, a filter, integrator, differentiator, or a variety of other circuits. You can’t run it from a single 5V power supply. Simple modifications can scale the current or even invert it.

AF modulator in Transmitter what is the A? Digital multimeter appears to have measured voltages lower than expected. PNP transistor not working 2.

Y Guaranteed 5 m V C drift. The inverting pin of IC1 is connected to the positive terminal of battery. But some ICs, such as op amps, are available in metal cans for shielding which can be easily opened with a hacksaw or even better a lm38 saw. Bandwidth and slew rate are proportional to 1 C f. Photos of the die reveal the tiny circuitry of the chip eatasheet well as unused components that make the chip more complex than necessary.

More data would be useful. This image shows one resistor with about 20 segments. The superbeta emitter is not wired to anything, which raises the question of why it exists. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. Die photos and analysis of the LM op amp. Post as a guest Name. Pads on the die are connected to the pins with thin bond wires. Testing low drift amplifiers is also difficult Standard drift.

The current on the right copies the current on the left. Die photo of the op amp. Due to very small difference at input of op-amp mVthe output of op-amp is oscillating between 1. Put it between the OP Amp and daatasheet transistor Don’t forget to raise the value of the resistor – You don’t want to over load the gate.
