5.3.2
MODULATOR INPUT RANGE AND
SATURATION POINT
For a specified voltage reference value of 1.2V, the
specified differential input range is ±600 mV. The input
range is proportional to VREF and scales according to
the VREF voltage. This range ensures the stability of the
modulator over amplitude and frequency. Outside of
this range, the modulator is still functional; however, its
stability is no longer ensured and therefore it is not
recommended to exceed this limit. The saturation point
for the modulator is VREF/1.5, since the transfer
function of the ADC includes a gain of 1.5 by default
(independent from the PGA setting). See Section 5.5
“ADC Output Coding”
).
5.3.3
BOOST SETTINGS
The delta-sigma modulators include a programmable
biasing circuit, in order to further adjust the power
consumption to the sampling speed applied through
the MCLK. This can be programmed through the
BOOST<1:0> bits, which are applied to all channels
simultaneously.
The maximum achievable analog master clock speed
(AMCLK), the maximum sampling frequency (DMCLK)
and the maximum achievable data rate (DRCLK),
highly depend on BOOST<1:0> and PGA_CHn<2:0>
settings. Table 5-2 specifies the maximum AMCLK
possible to keep optimal accuracy in the function of
BOOST<1:0> and PGA_CHn<2:0> settings.
