Exiting Partial and Full Power-Down Modes
Drive CNVST low and allow at least 14 SCLK cycles to
elapse before driving CNVST high to exit partial or full
power-down mode. When exiting partial power-down
mode, conversions can begin immediately without hav-
ing to wait for the reference to wake-up. When exiting
full power-down mode, allow at least 2ms recovery time
after exiting to ensure that the internal reference has
settled.
In partial or full power-down mode, maintain idle SCLK
low or high to minimize power.
Applications Information
SPI and MICROWIRE
The MAX1377/MAX1379/MAX1383 are compatible with
all four modes programmed with the CPHA and CPOL
bits in the SPI or MICROWIRE control register.
Conversion begins with a CNVST falling edge. DOUT_
goes low, indicating a conversion is in progress. Two
consecutive 8-bit reads are required to get the full 12
bits from the ADC. DOUT_ transitions on the rising edge
of SCLK. DOUT_ is guaranteed to be valid tDOUT after
the rising edge of SCLK and remains valid until tDHOLD
after the next SCLK rising edge (see Figure 13).
