MAX1080/MAX1081
Hardware Power-Down
Pulling SHDN low places the converter in hardware
power-down. Unlike software power-down mode, the
conversion is terminated immediately. When returning
to normal operation from SHDN with an external refer-
ence, the MAX1080/MAX1081 can be considered fully
powered up within 2s of actively pulling SHDN high.
When using the internal reference, the conversion
should be initiated only after the reference has settled;
its recovery time is dependent on the external bypass
capacitors and shutdown duration.
Power-Down Sequencing
The MAX1080/MAX1081 automatic power-down modes
can save considerable power when operating at less
than maximum sample rates. Figures 10 and 11 show
the average supply current as a function of the sam-
pling rate.
Using Full Power-Down Mode
Full power-down mode (FULLPD) achieves the lowest
power consumption, up to 1000 conversions per chan-
nel per second. Figure 10a shows the MAX1081’s
power consumption for one- or eight-channel conver-
sions utilizing full power-down mode (PD1 = PD0 = 0),
with the internal reference and the maximum clock
speed. A 0.01F bypass capacitor at REFADJ forms an
RC filter with the internal 17k
reference resistor, with a
200s time constant. To achieve full 10-bit accuracy,
seven time constants or 1.4ms are required after
power-up if the bypass capacitor is fully discharged
between conversions. Waiting this 1.4ms duration in
