Single Power And Low Power Consumption Instrument Amplifier Circuit Composed Of INA102

Published:2011/5/19 9:40:00 Author:Robert | Keyword: Single Power, Low Power Consumption, Instrument Amplifier

The single power and low power consumption instrument amplifier circuit is shown in the picture below. This circuit uses the low power consumption instrument integrated amplifier INA102, whose internal resistance has excellent temperature performance and working stability. There are two 100kΩ resistance in the picture making up a voltage divider (to divide the power voltage). It makes the out-phase input port have a 4.5V DC voltage. So when there is no input signal its output voltage is still DC 4.5V. Its voltage magnification times would be 100 according to the circuit connection in the picture.   (View)

XTR108 Three-Wire RTD Connection Circuit

Published:2011/5/19 18:07:00 Author:Robert | Keyword: Three-Wire, RTD, Connection

The XTR108 three-wire RTD connection circuit is shown in the picture shown below. It may cause errors by connecting RTD sensor lead resistance. Using the 1 and 2 connection method in the picture, the lead resistances would be the same if 1 and 2 have the same lead length to XTR108. And the caused disturbance size and direction also are the same. This disturbance is common-mode voltage. The common-mode voltage ca be limited by the XTR108's PGA. This circuit has 5 optional temperature range by choosing R21~R25 to choose 5 different minimum temperature features.   (View)

XTR110 Voltage-Current Converter Circuit

Published:2011/5/19 17:45:00 Author:Robert | Keyword: Voltage-Current Converter

As shown in the picture, when the output current exceeds 40mA the internal resistance 50Ω in the XTR110 (R9) should be replaced by external resistance REXT. REXT is connected between the 13 foot and 16 foot. REXY=R9(original span/required span). For example, the XTR110 in the picture's original span is 20mA and now the required span is 10A. If R9=50Ω, then the REXT=R9=50X(20/10000)=0.1Ω.   (View)
