AD7705/AD7706
OUTPUT NOISE (5 V OPERATION)
Table 5 shows the AD7705/AD7706 output rms noise for the
selectable notch and −3 dB frequencies for the parts, as selected
by FS0 and FS1 of the clock register. The numbers given are for
the bipolar input ranges with a V
These numbers are typical and are generated at an analog input
voltage of 0 V with the parts used in either buffered or unbuffered
mode. Table 6 shows the output peak-to-peak noise for the
selectable notch and −3 dB frequencies for the parts.

Note that these numbers represent the resolution for which
there is no code flicker. They are not calculated based on rms
noise, but on peak-to-peak noise. The numbers given are for
bipolar input ranges with a V
unbuffered mode. These numbers are typical and are rounded
to the nearest LSB. The numbers apply for the CLKDIV bit of
the clock register set to 0.
