Started testing a new load cell and noticed that ADC results were odd:
Weight (kg) AIN (mV) ADC 24bits (hex)
2kg 3.7mV 009752F0
4kg 6.3mV 00FFEC90
4.1kg 6.4mV 0082B118
Above 6.3mV the codes appear to drop (excitation voltage is 3.24V).
i am using the part number AD7780 its a moderate precision ADC which gives out a quite acceptable output for me and i want to expand my application as i want to put 12 parallel AD7780 to communicate with one microcontroller but unfortunately…
Yes, you can provide an external signal conditioning circuitry (i.e. amplifier, etc.) to increase the transducer output signal. But this is only advisable when the internal solution does not meet your requirements. AD7780 offers integrated solution…
we did some EMC testing (radiated immunity) on some of our parts (AD7192 and AD7780). The application notes (AN-1186 and AN-1187) are available on the AD7780 and AD7192 product pages.
Hellow. I'm reading data from AD7780. But I can read only once. Help me pls. The PDRST pin is always "ONE".
I'm wanting to use the AD7780 in a non ratiometric configuration which means that Vref does not equal AVDD. Page 3 of the datasheet says that the Differential input Voltage Range = +/-Vref / gain when the assumption is that Vref = AVDD. Does…
I am using XP 32 bit and have administrator privileges but I click setup and nothing happens. downloaded software instead of using CD and same thing. I see 32 and 64 bit files in the install folder.
I am using AD7780 24-bit ADC for reading loadcell. But, not find the 32-bit output value format of AD7780 in datasheet.
And I am need data/clock timing information.
My code is below. Where is wrong?
