3 V OPERATION
Table 33 shows the AD7707 output rms noise and peak-to-peak
resolution for the selectable notch and 3 dB frequencies for the
part, as selected by FS0, FS1, and FS2 of the clock register. The
numbers are given for all input ranges with a VREF of 1.25 V, HBIAS
= 1.25 V, HICOM = AGND, and AVDD = 3 V. These numbers
are typical and are generated at an analog input voltage of 0 V
for unbuffered mode of operation. Table 34 meanwhile shows
the output rms noise and peak-to-peak resolution for buffered
mode of operation with the same operating conditions as for
Table 33. It is important to 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
output noise comes from two sources. The first is the electrical
noise in the semiconductor devices (device noise) used in the
implementation of the modulator. Secondly, when the analog
input is converted into the digital domain, quantization noise is
added. The device noise is at a low level and is independent of
frequency. The quantization noise starts at an even lower level but
rises rapidly with increasing frequency to become the dominant
for the bipolar input ranges. For the unipolar ranges, the rms
noise numbers are the same as the bipolar range but the peak-
to-peak resolution is now based on half the signal range, which
effectively means losing 1 bit of resolution.
