ADuC824: differential input

emassa

Q
I have trouble understanding the REFIN(+) and REFIN(-) pins on the ADuC824.
Also, whats their relation to differantial/unipolar input?

Are there any referance board like for the ADuC812, where the schematic is
available?

ADUC824/834 microconverter's temperature sensor

emassa

Q
Can you please supply the specification for the on-board temperature sensor on
the ADUC824/ADUC834 devices? I need an accurate description of the temp
channel. This doesn't appear in the datasheets. I suspect it might be a biased

ADUC824 EEPROM Problem

rick_

Hello,

I use the ADUC824 and ADUC834 for measuring a sensors bridge voltage. After AD-Conversion the MCU removes an offset value and multiplies the ADC-value by a gain factor. Both numbers (offset and gain) are stored in the EEPROM during a calibration…

AD7738: Timing specs

GenevaCooper

Q

Please refer to Data Sheet Rev. 0 page 4. table: Timing Spec. What is the
meaning of t9: will the DOUT be tristated 10 to 80 ns after SCLK rising edge
sampling LSB, no matter if -CS is kept low? (t9 is referred to SCLK, not -CS)
Does it apply…
