Power Consumption
Figure 29 plots the variation of quiescent current consumption with supply voltage V
, as well as the
DD
distribution between the 3 PGA stages and the ADC (see Table 34). As shown in Figure 30, if lower sampling
frequency is used, the quiescent current consumption can be lowered by reducing the bias currents of the PGAs
and the ADC with registers IB_AMP_PGA [1:0] and IB_AMP_ADC [1:0]. (In Figure 30, IB_AMP_PGA/ADC[1:0]
= '11', '10', '00' for f
= 500, 250, 62.5 kHz respectively.)
S
Quiescent current consumption vs. temperature is depicted in Figure 31, showing a relative increase of nearly
40% between -45 and +85°C.
