how to use instrumentation amplifier AD620?

Figure Load Resistance 0 Large Signal Response and Settling Time H Page 9 of Output Voltage Swing vs.. Small Signal Response AD Small Signal Pulse Response.. Settling Time to 0. Gain Nonlinearity. Settling Time vs H Page 10 of 20 Figure Gain Nonlinearity Settling Time Test Circuit Table 4 shows how to calculate the effect various error sources have on circuit accuracy.

The internal gain resistors. Monolithic construction and laser wafer trimming allow the tight matching and tracking of circuit components. In the typical application. R1 and R2. The value of RG also determines the transconductance of the preamp stage.

Analog Devices AD620 Specification Sheet

This has three important advantages: Absolute value trimming allows the user to program gain accurately to 0. H Page 12 of Simplified Schematic of AD The AD is a monolithic instrumentation amplifier based on a modification of the classic three op amp approach.

As RG is reduced for larger gains. The unity-gain subtractor. download Table 4. This is because a three op amp type in-amp has two op amps at its inputs. Regardless of the system in which it is being used. In more complex systems with an intelligent processor. AD Note that for the homebrew circuit. Make vs. In simple systems. Since it delivers low noise and drift. Adding the AD and a buffered voltage divider allows the signal to be conditioned for only 3. R3 In such a circuit.

Small size and low cost make the AD especially attractive for voltage output pressure transducers. Proper safeguards.

H Page 14 of 20 ADJ. Low leakage diodes such as the BAV can be placed at the inputs to reduce the required protection resistance. This current. Table 5 shows required values of RG for various gains. Parasitic resistance should be kept to a minimum for optimum CMR. For input voltages beyond the supplies. The output voltage.

Figure 42 demonstrates such a configuration. The filter limits the input Rev. For any arbitrary gain. H Page 15 of The low errors of the AD are attributed to two sources. These can be the same resistors as those used in the RFI filter. The op amp buffers the reference terminal to maintain good CMR.

This is true for all gains and power on and off. RG can be calculated by using the formula: In practice. Precision Voltage-to-Current Converter Operates on 1.

Does not include effects of external resistor R One input grounded. This is defined as the same supply range which is used to specify PSR.
