Part Number: INA331 Other Parts Discussed in Thread: OPA336 , INA351 , LM7705 , OPA333 Tool/software: For instrumentation amplifier, INA331, this is being used as differential amplifier with R1 = 100K digipot and R2 = 100K. From DS, this indicates that…
Part Number: INA331 Tool/software:
What is the max input offset voltage drift over temperature of the INA331?
Only typical are specified on the data sheet.
Part Number: INA331 Tool/software: Dear Team,
My customer is designing a sensor in which the INA331 will have some input voltage while it doesn't have a supply voltage.
Can you please advise what's the max allowed voltage in case of an unpowered mode…
Part Number: INA331 Other Parts Discussed in Thread: OPA340 Hello,
Q1.
I am planning to use a DIGITAL POTENTIOMETER at the P1 location in the circuit to adjust the gain of INA331. The output range of INA331 is -1V to 1V. Is it acceptable to use a…
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 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 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 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,…
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 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 to…
