MAX1178/MAX1188
Power-Down Modes
Select standby mode or shutdown mode with the R/C
bit during the second falling edge of CS (see the
Selecting Standby or Shutdown Mode section). The
MAX1178/MAX1188 automatically enter either standby
mode (reference and buffer on) or shutdown (reference
and buffer off) after each conversion, depending on the
status of R/C during the second falling edge of CS.
Internal Clock
The MAX1178/MAX1188 generate an internal conver-
sion clock to free the P from the burden of running the
SAR conversion clock. Total conversion time (tCONV)
after entering hold mode (second falling edge of CS) to
end-of-conversion (EOC) falling is 4.7s (max).
Applications Information
Starting a Conversion
CS and R/C control acquisition and conversion in the
MAX1178/MAX1188 (Figure 2). The first falling edge of
CS powers up the device and puts it in acquire mode if
R/C is low. The convert start is ignored if R/C is high.
The MAX1178/MAX1188 need at least 12ms for the
internal reference to wake up and settle before starting
the conversion (CREFADJ = 0.1F, CREF = 10F), if
powering up from shutdown.
