I would like to confirm of output data bit of AD7760. I understood that AD7760 is 24bit ADC, but it wiil be 15bit ADC on modulatior data output mode according to the datasheet. Is my understanding correct?
The AD7760 is a 24 bit ADC, this is when filters not bypass. But when the filers are all bypassed with control registers bits BYPF1, BYPF3 and DEC[2:0] are set to zero, the AD7760 is in modulator mode. The output is in 16 bit twos compliment format but this data is scaled to 15 bits.
Thank you for your answer. I understand.
I also would like to confirm about Evaluation software of AD7760. Are the register setting of BYPF1, BYPF3 and DEC[2:0] set to zero when we click Modulator Enable button of the GUI?
Thanks & Regards,
Let me get back to you on this. I need to check details.
Yes the DB[4:0] are zero when clicking the Modulator enable button of the AD7760 Evaluation Software GUI.
Thank you for your answer.
Thanks 6 regards,
