Other Parts Discussed in Thread: INA2128 , INA128 , INA2126 , INA126 Hi,
I'm having a problem using the INA2128 with a load cell resistive bridge. circuit attached. The impedance of the bridge is approximately 1K. The exitation on the bridge is 8VDC. So the…
Hello Kailyn,
The ADS1278 has a lower input impedance at higher sample rates, which could cause a shift in the INA2128 output over temperature. The reference input current also increases with higher sample rates, which could also cause a shift in the…
Other Parts Discussed in Thread: INA2134 , INA2128 , INA128 , INA134 , DRV134 , INA137 Hello, I have a need to bring a signal into my circuit whilst preserving its fidelity as best as possible. It isn't audio, but it has the same sort of requirements as the…
Hi Bryan,
The sensitivity that I am trying to achieve is 1ADC per 0.5gm. With 200gm the bridge varies 0.08mV, being excited with 3.3V.
INA2128 with gains of 2000 +/- 1000, depending on the application
If I can detect 0.5gm of change, it would be eno…
Thanks for the reply, Collin. Attached see my drive amp (INA2128) and 1.59 kHz cutoff input RC filter to the ADC. I realize now more clearly how that filter acts as a flywheel for filling the S/H circuitry in the ADC. Note that the resistor in the RC…
Other Parts Discussed in Thread: INA2128 , INA333 , INA128 , INA111 Hello, I am getting the signal that you can see in the attached pdf 5545.INA2128U noise.pdf from a bio-amplifier input stage made around one INA2128U. Bursts reach 120µVpp while the EEG machine…

Hi,
I made a design of surface EMG and that circuit as attached. In this circuit i used INA2126 for behalf of INA 2126 and…
Other Parts Discussed in Thread: ADS1256 , ADCPRO , ADS1271 , INA2128 I have a MMB0 development mother board which I have used with the ADS1271 EVM 24bit ADC and TI's software. I now want to use the MMB0 mother board with a ADS1256 EVM 24bit ADC board but…
Other Parts Discussed in Thread: ADCPRO , ADS1274 , ADS1256 , ADS1255 Hi Greg
I have posted this as a new question as I did not get a reply. Yes I would be very interested in the beta software for the ADCpro and ADS1256EVM. At this time I am using the ADS1271EVM…
