Part Number: INA106 Tool/software: Hi team,
My customer is using INA106 for voltage sensing, VS+ VS- are +/-12V supply. Measure a voltage+ to GND voltage signal, max voltage is 6Vrms, so INA106 will see differential input 6V, and common mode input voltage…
Part Number: OPA547 Other Parts Discussed in Thread: INA106 We are using the OPA547 as part of a voltage controlled current source on an output card on one of our controller systems. We supply the OPA with +/-15V. We have three resistors, configurable…
Part Number: INA105 Other Parts Discussed in Thread: INA106 , INA131 , Hello,
becomes an instrumentation amplifier (e.g. INA105, INA106, INA131) less accurate, if its dual supply voltage is not balanced (e.g., + - 5V; but e.g. with + 8V and -5V)?
Best regards…
Look at INA106. If you cannot get what you need you can do it with an op amp and a resistor network that has ratio matched resistors for best common mode rejection ratio.
JACR,
You said you are implementing a Howland with the INA105/INA106. Can you please post your exact circuit (with everything connected)? Please describe what you mean by "does not work..." Under what condtions does it work?
Thanks,
Matt
