Other Parts Discussed in Thread: ADS1220EVM , ADCPRO , ADS1220 , ENERGIA I am trying to use the ADS1220EVM to measure a very small change (5mV/V FS) of an analog pressure sensor. I am trying to use this EVM to increase the resolution of the signal coming…
Other Parts Discussed in Thread: ADS1220EVM , ADCPRO , ADS1220 , ADS1120 , ADS1120EVM I'm trying to work with an ADS1220EVM and ADCPro.
I have both ADCPro and the ADS1220EVM plugin installed.
However, when I connect the EVM board, it doesn't find the correct…
Other Parts Discussed in Thread: ADS1220EVM , ADS1220 I am makeing a project using ADS1220 for full bridge measurement with ratiometric reference. 5V at the analog side and 3.3V at the MCU side ( a Cortex M0). I am using the ADS1220EVM as a reference design…
Other Parts Discussed in Thread: ADS1220 When jumper JP7 is open, an external supply voltage (+5V) can be fed in to connector J7 to power the module. When I do this, the module never enumerates as a USB device once plugged into a PC. If JP7 is shorted…
Hello Art, thank you for the hint, the upload text does not look like a button so that was confusing.

Oliver,
You do want some filtering between the INA and ADC. This is for antialiasing. Basically, you want this filter to have a cutoff frequency a decade or more below the modulator frequency. For this device the modulator frequency options are listed…
Charles,
Some background on the amplifier circuit: R2 is feeding back the "peak detected" voltage for comparison to new input signals from Vg1. For your information, here is a link to document on a "half wave rectifier circuit" that is the core…
Other Parts Discussed in Thread: ADS1120 , ADS1220 , ADCPRO , ADS1220EVM Could you please introduce the lowest power consumption temperature measurement solution for RTD temperature sensor ?
In addition, as the recommended solution, we request the average…
Shibin,
One simple approach is to use an instrumentation amplifier (INA) to convert the bridge output from a differential signal to a single ended signal. The output of the INA is then divided by a voltage divider and connected to the ADC input. One way…
Hi Carl,
Before I posted the screen shots, I downloaded and installed the most current plugin from the web on 9/9/2019. I reinstalled again today, so I don't think there is anything wrong with the installer for the plugin.
You could try installing…
