MAX1067/MAX1068
Power-Down Modes
Table 5 shows the MAX1067/MAX1068 power-down
modes. Three internal reference modes and one exter-
nal reference mode are available. Select power-down
modes by writing to bits 2 and 1 in the command/con-
figuration/control register. The MAX1067/MAX1068
enter the selected power-down mode on the rising
edge of CS.
The internal reference stays on when CS is pulled high,
if bits 2 and 1 are set to zero. This mode allows for the
fastest turn-on time.
Setting bit 2 = 0 and bit 1 = 1 turns both the reference
and reference buffer off when CS is brought high. This
mode achieves the lowest supply current. The refer-
ence and buffer wake up on the falling edge of CS
when in SPI/QSPI/MICROWIRE mode and on the falling
edge of DSPR when in DSP mode. Allow 5ms for the
internal reference to rise and settle when powering up
from a complete shutdown (VREF = 0, CREF = 1F).
The internal reference stays on and the buffer is shut off
on the rising edge of CS when bit 2 = 1 and bit 1 = 0.
The MAX1067/MAX1068 enter this mode on the rising
edge of CS. The buffer wakes up on the falling edge of
CS when in SPI/QSPI/MICROWIRE mode and on the
falling edge of DSPR when in DSP mode. Allow 5ms for
VREF to settle when powering up from a complete shut-
down (VREF = 0, CREF = 1F). VREFCAP is always equal
to +4.096V in this mode.
Set both bit 2 and bit 1 to 1 to turn off the reference and
reference buffer to allow connection of an external ref-
erence. Using an external reference requires no extra
wake-up time.
Operating Modes
External Clock 8-Bit-Wide Data-Transfer Mode
(MAX1067 and MAX1068)
Force DSPR high and DSEL low (MAX1068) for SPI/
QSPI/MICROWIRE-interface mode. The falling edge of CS
wakes the analog circuitry and allows SCLK to clock in
data. Ensure the duty cycle on SCLK is between 45% and
55% when operating at 4.8MHz (the maximum clock fre-
quency). For lower clock frequencies, ensure the
Multichannel, 14-Bit, 200ksps Analog-to-Digital
Converters
