Hi, Zach
The diagram above shows the circuit and noise waveform when using a single power supply for INA331. When changing to dual power supplies for INA331, the noise waveform changes as shown below. In all of the above tests, the input is in an inactive…
Part Number: INA331 Hello TI Support Team,
I downloaded the INA331 example PSpice project and made some modifications to be more in-line with my application (current draw monitoring on a power supply sense resistor).
In the configuration of the circuit…
Part Number: INA331 Hi Amps Team,
I have a fairly simple question about the input impedance spec of the INA331( and TI's amplifiers in general):
I wanted clarity that the impedance spec on the input was in reference to ground and not the differential…
Part Number: INA331 Hi all
when i see the datasheet of INA331, I find that the output voltage of INA331 can not be more than VDD-1.2v(page9 &page10)
So does it means that if my VDD=3.3v, my maximum output signal voltage can not be more than 2.1V…
Part Number: INA331 I'm currently designing a load cell front end circuit for a battery powered device. The load cell is enabled and disabled by a P channel FET, which also enables the INA331 and drives a shunt reference for the INA331. The goal is…
Part Number: INA331 Other Parts Discussed in Thread: LM7705 Team,
My customer has the following question:
I believe you guys took over burr brown INA331. I need help with it. I see in datasheet page 9 the gain is set by R1 and R2 to get desired gain …
Part Number: INA331 Hi all Would you mind if we ask INA331? Is it possible to use with dual suply voltage like as V+=2.5V and V-=-2.5V? Kind regards, Hirotaka Matsumoto
Part Number: INA331 Other Parts Discussed in Thread: INA231 , INA326 I'm using the INA331 with a gain of 5 and Vs = 5V. I'm getting a maximum Vout of 4.3V. Data sheet states Vout will not go to rail with gains < 10 (only when gain set to 5). However…
Hi Bivin,
I see you have vin- connected to ground, and vin+ is a signal between 10uV and 10mV. In this case you are violating the valid common-mode input range of the INA2331.
When operating on a single-supply, the INAx331 is designed to interface with…
