Part Number: INA826 Other Parts Discussed in Thread: INA331 , INA332 , , INA823 Hi TI,
I have been looking extensively for an instrumentation amplifier that:
* works at 3V
* has a bandwidth over of 4kHz
* has a gain of 1000
* has a small footprint…
We have several inputs on the ADS7828 driven by TI INA331 Instrumentation Amplifiers. The output of each INA331 has a 22uF capacitor to ground and the power down characteristics are given by the scope trace above where the yellow waveform is the supply…
Part Number: INA2331 Other Parts Discussed in Thread: INA331 , TINA-TI , LM27762 , AFE5816 , OPA325 Hi
I'm implementing below circuitry for amplifier section. The input signal voltage will range between 10uV to 10mV. But in the current circuit, the…
Hi Yamagishi-san,
You can take a look at the portfolio here: https://www.ti.com/amplifier-circuit/instrumentation/products.html#p480=1
Perhaps something like INA331 or INA332? These are single-supply devices but maximum voltage is lower.
Best regards…
Part Number: INA333 Other Parts Discussed in Thread: TINA-TI , INA331 , INA828
Hello, I have a INA333 based project, which goal is to reach 1uV resolution in voltage measurement. I plan to use a 0.002 Ohm shunt resistor at the down side of a half-bridge…
Tran,
1. The Ref pin on INA331 is used to shift the signal. This should be connected to Vref/2.
2. The positive supply on INA331 is connected to a voltage equal to Vref. In the example circuit I showed 5V. Note: I would use an LDO to generate the…
Part Number: INA111 Other Parts Discussed in Thread: INA331 , INA818 , INA121 , INA332 , , LMP7721 , TINA-TI Hello all,
I am in the process of developing a circuit to measure the device current, the minimum device current in the order of picoamp. The…
Other Parts Discussed in Thread: INA331 , TINA-TI Hi,
May I know more info. on thermal transient behavior of INAs & OPAs (specifically INA331). Because in one of our amplifiers we experience higher overshoots of the output during the temperature transients…
Hello Baptiste,
Here are some suggestions:
1) I think this was drawn in MS Paint. I recommend using the schematic capture program from your PCB tool of choice for schematics (e.g. PCB Artist). That way you don't have to draw it multiple times. 2)…
