OUTPUT NOISE FOR HIGH LEVEL INPUT CHANNEL
AIN3 (5 V OPERATION)
Table 11 shows the AD7707 output rms noise and peak-to-peak
resolution in unbuffered mode for the selectable notch and 3 dB
frequencies for the part, as selected by FS0, FS1, and FS2 of the
clock register. The numbers given are for the ±10 V, ±5 V, 0 to
5 V and 0 V to 10 V ranges with a VREF of 2.5 V, VBIAS = 2.5 V,
HICOM = AGND, and AVDD = 5 V. These numbers are typical
and are generated at an analog input voltage of 0 V. Table 12
meanwhile shows the output rms noise and peak-to-peak
resolution in buffered mode. 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. Operating the high level channel with a
gain of 2 in bipolar mode gives an operating range of ±10 V.
Operating at a gain of 2 in unipolar mode gives a range of 0 V
to +10 V. Operating the high level channel with a gain of 4 in
bipolar mode gives the ±5 V operating range. Operating at a gain
of 4 in unipolar mode gives an operating range of 0 V to 5 V.
Noise for all input ranges is shown in Output Noise For High Level
Input Channel, AIN3 section. 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 modula-
tor. 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 noise source. The numbers
in Table 11 and Table 12 are given 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.
