Pulling SHDN low places the converter in hardware
power-down (Table 6). Unlike software power-down
mode, the conversion is not completed; it stops coin-
cidentally with SHDN being brought low. SHDN also
controls the clock frequency in internal clock mode.
Letting SHDN float sets the internal clock frequency to
1.8MHz. When returning to normal operation with SHDN

Pulling SHDN high sets internal clock frequency to
225kHz. This feature eases the settling-time requirement
for the reference voltage. With an external reference, the
MAX146/MAX147 can be considered fully powered up
within 2µs of actively pulling SHDN high.
