OUTPUT NOISE
AD7715-5
Table V shows the AD7715-5 output rms noise for the selectable notch and –3dB frequencies for the part, as selected by FS1 and
FS0 of the Setup Register. The numbers given are for the bipolar input ranges with a V
REF
of +2.5V. These numbers are typical
and are generated at a differential analog input voltage of 0V with the part used in unbuffered mode (BUF bit of the Setup Register
= 0). Table VI meanwhile shows the output
peak-to-peak
noise for the selectable notch and –3dB frequencies for the part.
It is im-
portant to note that these numbers represent the resolution for which there will be no code flicker. They are not calculated based on rms noise but
on peak-to-peak noise
. The numbers given are for the bipolar input ranges with a V
REF
of +2.5V and for the BUF bit of the Setup
Register = 0. These numbers are typical, are generated at an analog input voltage of 0V and are rounded to the nearest LSB.
Meanwhile, Table VII and Table VIII show rms noise and peak-to-peak resolution respectively with the AD7715-5 operating under
the same conditions as above except that now the part is operating in buffered mode (BUF Bit of the Setup Register = 1).
