Information furnished by Analog Devices is believed to be accurate and. Input common-mode voltage range allows the AMP04 to handle signals with full accuracy from ground to within 1 a,p04 of the positive supply. Temperature 5V Figure Consult factory to negotiate specifications based on dice lot qualifications through sample lot assembly and testing. Due to environmental concerns, ADI offers many of our products datassheet lead-free versions.

Combining with the single supply ADG quad analog switch, the AMP04 makes a useful programmable gain amplifier that can handle input and output signals at zero volts.

What is more important, large thermal gradients can create not only unexpected changes in component values, but also generate significant thermoelectric voltages due to the interface between dissimilar metals such as lead solder, copper wire, gold socket contacts, Kovar lead frames, etc.

International prices may differ due to local duties, taxes, fees and exchange rates. Extended Positive Common-Mode Range On the high side, other instrumentation amplifier configurations, such as the three op amp instrumentation amplifier, can have severe positive common-mode range limitations. In a single supply system the signal input cannot be allowed to go below ground, and therefore the signal must be offset to accommodate this change in polarity.


Input common-mode voltage range allows the AMP04 to handle signals with full accuracy from ground to within 1 volt of the positive supply. It is a less desirable nulling circuit than the previous method. And the output can swing to within 1 volt of the positive supply.

Voltage Noise Density vs. Again, the use of equal resistance values will create a common input error voltage that is rejected by the amplifier. Clearly this is not possible in a single supply environment.

Finally substitute a Please Select a Region. Driven shields am0p4 easily realized with the AMP For this circuit to function, VOB must swing datashfet No license is granted by dxtasheet or otherwise under any patent or patent rights of Analog Devices. AMP04s are available in plastic and.

Component layout that takes into account the power dissipation at critical locations in the circuit and minimizes gradient effects and differential common-mode voltages by taking advantage of input symmetry will minimize many of these errors. At that point the output is at the saturation limit. In single supply systems it could be connected either to the negative supply or to a pseudoground between the supplies. This can be one of 4 stages: SIMetrix mode is ideal for the simulation of general non-switching circuits.

The various ranges specified are as follows:. Temperature Datashert This is the acceptable operating range of the device.

It offers an excellent combination of accuracy, low power consumption, wide input voltage range, and excellent gain performance. Input offsets attain very low temperature drift by proprietary lasertrimmed thin-film resistors and high gain amplifiers. These consist primarily of input and output offset voltages and leakage currents.


Please consult the datasheet for more information.

Examination of the simplified schematic shows that the potentials at the gain set resistor pins of the AMP04 follow the inputs precisely. Cable Shield Drivers —7— AMP04 Compensating for Input and Output Errors Noise Filtering To achieve optimal performance, the user needs to take into account a number of error sources found in instrumentation amplifiers.

This is the acceptable operating range of the device. Package Description The package for this IC i.

At zero volts out, the output is in saturation to the negative rail and the output voltage is indistinguishable from the normal offset error. To illustrate, take for example the single supply, gain of instrumentation amplifier as in Figure 2.

Careful circuit layout, including good grounding and signal routing practice to minimize stray coupling darasheet ground loops is recommended. Input Noise Voltage Figure A major path for these error voltages will be found in the power supply lines. We do take orders for items that are not in stock, so delivery may be scheduled at a future date.

Precision Single Supply Instrumentation Amplifier. Gain bandwidth is over kHz. A proprietary input structure limits input offset currents to less. Pricing displayed for Evaluation Datasheett and Kits is based on 1-piece pricing.
