Part Number: INA143 Other Parts Discussed in Thread: ADS1284 , PGA281 , INA145 Hi to all!
I'm trying to design ADC with variable full scale, so I need selectable variable gain stage (attenuator). In this discussion it was explained how get gain different…
Part Number: INA143 Hi Team,
Good day. I am posting this inquiry on behalf of the customer.
"We are currently using the INA143U amplifier in our design and looking to use the INA143UA as a substitute device due to availability issues. In comparing…
Part Number: INA143 Other Parts Discussed in Thread: INA146 , INA821 , INA828 , INA188 Hi,
Can I make the gain of INA143 smaller than 10 by adding two resistors at the input side, seen below? I need the gain is around 7. If so, what is the bandwidth at G…
Part Number: INA143 Other Parts Discussed in Thread: INA105 I saw on the datasheet that this part can be used as a voltage controlled current source. Is there an application circuit for this?
Part Number: INA143 I have an application where I receive 20V RMS sine wave and I am planning to use INA413 to attenuate to 2 V RMS. Simulation works fine. I wish to see the impact on output, when power supply to op amp is turned off and inputs are applied…
Brendan,
A voltage divider is a common approach to this issue. It will have a gain error and drift associated with the tolerance of the divider. If you are doing a calibration then the gain error can be eliminated. A tolerance of 0.1% and drift of 20ppm…
We looked at those options, but the issue is we need the programmable gain stage, as we use a gain of approximately 0.14. We could change some resistor values and use a gain of 0.1, but the inputs, SENSE and REF pins of the INA143 are in the exact opposite…

Hello?
As title, please review for circuit.
Input and Output range of AMC1311 are 0 to +2V.
Gain of first INA326 is 10.(2V to 20V range)
Gain of second INA326…
