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
Hi Xu,
why have you mounted R910? The REF pin of INA331 must be driven very low ohmically, like shown in figure 6 of datasheet. A 150R resistance to signal ground at this point is no good idea, because it will erode the symmetry of the INA331 and by…
Other Parts Discussed in Thread: INA331 , INA326 , INA125 Hi, I'm using the INA331 as amplifier for load cell (wheastong bridge, 2000kg, 5VDC exitation, I/0 resistence aroung 350 ohms) with 3mV/V, so it has 15 mV at full scale.
The cell load works ok…
Hello Christian,
Sorry for the delay.
The concept is discussed at the beginning of part 2 of the following stability series:

The analysis of the stability of this circuit is quite complicated…
Other Parts Discussed in Thread: INA331 , INA326 Hi,
We are using INA331 in our design. The input voltage range is 123mV to 300mV. But according to datasheet the Input Common-Mode Range is 0.55 to 3.8V for Vs = 5V. Is there any effect on our input range…
Hi Pete,
okay, we will go forward and try to improve the INA331's decoupling and also correct the usage of the amplification-setting resistors.
At the moment, we have a 0,1uF cap at the GND (V-) pin of the INA331 between the GND-Plane and the VDD…
Other Parts Discussed in Thread: INA331 , INA333 , INA326 Dear Sir's,
Kindly asking for your opinion, I am planning to connect INA331 with gain (G=5) to sensor at each input terminal. The signal from the sensors are expected to be of low frequency…
