Hi, 
I need to amplify the voltage drop measured across shunt resistor - (1mohm). The maximum current through the resistor is 62A for our requirement. 
So, the voltage drop would be 62mV.We need to amplify the drop with…

Hello, my name is Chanhee Moon.

To get straight to the point, I’m trying to design a differential TIA using the OPA855.
Using Texas Instruments' TINA simulator, I set up…

Hi! I've been locking a way to sense direct current in microamperes, my idea is to use a 1 ohm shunt resistor to pass from current to voltage, amplify it and sense it with an 10bits…

Is there an issue with connecting the Thermal Pad of the INA851 to ground rather than VS-? The datasheet says to connect to the most negative rail VS- but doesn't give any reasoning why. I'd like to know if there will be any function…

Hello,

What is the Thermal Tail Settling Behavior of this instrumentation amplifier? 

The intended application is for the amplifier to settle to 16 bits. 

Thanks

I have a circuit where I'm using the INA350ABSIDDFR part to amplify a signal. As per datasheet there are only two possible gains: 10x or 20x (selectable by the GS pin).

In my circuit I have…

In TIPD164 design, they have used INA826 and  INA159 for converting voltage and current source to required range for ADS1248 IC . Why cant we use INA826 directly using…

I have an INA821 instrumentation amplifier, he said his output noise at 0.1-10Hz is 2.5uV (assuming the input signal noise is lower than 2.5uV), I use a single supply of 10V to…

Hi Team,
I want to design a circuit that measures the readings from a strain gauge.
The Bridge resistance is 350 Ohms.
The excitation voltage is 12V.
I am following this application note as my reference…

Hello,

I need to amplify a signal with hundreds of mV DC + tenths of mV AC at tenths of kHz. The voltage signal will be read between a know…

Hi,

I'm building a circuit intended for use with an EEG product (you may as well consider this irrelevant, i'm using signal generator signals to input simulated, oversized EEG signals, to verify…

Hi,

I am currently designing a basic EEG circuit, i have centered the design around the INA118, the design is shown below.

I have followed the general/classic architechture…

Hi,

I tried to simulate INA849 with the following spec. 

• Vin+ : 3.5V
• Vin- : 3.4V
• Gain: 9
• Vdiff: 100mV
• VCM: 3.45V
• Vout observed: 1.0V
• Vout expected: 0.9V

Any clue?

Dear All, 

My query was regarding the use of INA826EVM (INA826 Evaluation Board) with a 4-wire load cell, and I just wanted to check whether the following connections are correct…

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 shunt…

Hi All,

I am using INA827 along with load cell for my ADC frontend. I would like to calibrate my ADC using external mV source. How can I achieve the same? I have shared my ciruit below.

Thanks!

Field transmitter is a general term that encompasses the common industrial process control systems: pressure, temperature, and flow. While pressure, temperature, and flow transmitters each pose distinct design challenges and considerations, some signal…

We are designing an instrumentation amplifier based on the LHM6703 SOT-23-6.  There was a previous request for the LMH730316 gerber files. TI replied that they didn't have…

I have watched videos and read articles about how to drive SAR A/D converters but there is only minimal information regarding Sigma-Delta converters.

In my application I want to drive…

Hi,

I want to level shift with gain an 2.5V mean, 1V p-p (1.5V to 3.5V) signal with INA188 instrumentation amplifier.

I want the output with 5V mean and 3V p-p. So I set gain resistor 25k to have 3 gain, and VIN- input to 2.5V. Also…

Hi .. 

            We are using TLV4170 as an instrumentation amplifier configuration with single supply voltage topology. What we are facing the issue is with 3.3Volts supply. For 5v supply…

Hi all,

I my free time, I designed the attached schematic. My intention is to monitor EMG signals from the arm muscles. The circuit is quite self explanatory, two electrodes connected…

Hello all,

I have run into a strange issue with the INA828 instrumentation amplifier. Below is a description of the problem. 

I am using the INA828 instrumentation amplifier to measure a negative voltage, which will eventually make its…
