MAX1156/MAX1158/MAX1174
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
MAX1156/MAX1158/MAX1174 automatically enter
either standby mode (reference and buffer on) or shut-
down (reference and buffer off) after each conversion,
depending on the status of R/C during the second
falling edge of CS.
Internal Clock
The MAX1156/MAX1158/MAX1174 generate an internal
conversion clock to free the microprocessor from the
burden of running the SAR conversion clock. Total con-
version 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
MAX1156/MAX1158/MAX1174 (see 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 MAX1156/MAX1158/MAX1174 need
at least 12ms (CREFADJ = 0.1F, CREF = 10F) for the
internal reference to wake up and settle before starting
the conversion, if powering up from shutdown.
