Figure 13. FULLPD/FASTPD Power-Up Sequence
Figure 14a depicts the MAX192 power consumption for
one or eight channel conversions utilizing full
power-down mode and internal reference compensa-
tion. A 0.01μF bypass capacitor at REFADJ forms an
RC filter with the internal 20k
reference resistor with a
0.2ms time constant. To achieve full 10-bit accuracy,
10 time constants or 2ms are required after power-up.
Waiting 2ms in FASTPD mode instead of full power-up
will reduce the power consumption by a factor of 10 or
more. This is achieved by using the sequence shown in
Figure 13.
Lowest Power at Higher Throughputs
Figure 14b shows the power consumption with
external-reference compensation in fast power-down,
with one and eight channels converted. The external
4.7μF compensation requires a 50μs wait after
power-up, accomplished by 75 idle clocks after a
