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)?
…
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.
Hi Yuyama-san,
Please see the attached for a data packet with general information on PCN20250326007. We do not have specific data collected for the INA133 as this PCN used INA105 as the representative device for the characterization comparison section…
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
HI User,
Please find attached "The Instrumentation Amplifier Handbook", by Neil P. Albaugh from the Burr-Brown days a few years back. The handbook discusses several topics related to instrumentation amplifiers that are quite useful today.
On the section…
Hi A,
synchronous detection (alias phase sensitive detection or synchonous demodulation) can be performed this way:

Dear Customer,
The INA117KU uses the standard TI leadframe, Cu alloy base with NiPdAu plating finish. Tin finish has not been used on this device for many years.
Lead finish is clearly defined in the product datasheet, addendum page 1.
