MAX1167/MAX1168
Digital Interface
The MAX1167/MAX1168 feature an SPI/QSPI/
MICROWIRE-compatible, 3-wire serial interface. The
MAX1167 digital interface consists of digital inputs CS,
SCLK, and DIN and outputs DOUT and EOC. The
MAX1167 operates in the following modes:
SPI interface with external clock
SPI interface with internal clock
SPI interface with internal clock and scan mode
In addition to the standard 3-wire serial interface modes,
the MAX1168 includes a DSPR input and a DSPX output
for communicating with DSPs in external clock mode and
a DSEL input to determine 8-bit-wide or 16-bit-wide data-
transfer mode. When not using the MAX1168 in the DSP
interface mode, connect DSPR to DVDD and leave DSPX
unconnected.
Command/Configuration/Control Register
Table 1 shows the contents of the command/configura-
tion/control register and the state of each bit after initial
power-up. Tables 2–6 define the control and configuration
of the device for each bit. Cycling the power supplies
resets the command/configuration/control register to the
power-on-reset default state.
Initialization After Power-Up
A logic high on CS places the MAX1167/MAX1168 in
the shutdown mode chosen by the power-down bits,
and places DOUT in a high-impedance state. Drive CS
low to power up and enable the MAX1167/MAX1168
before starting a conversion. In internal reference
mode, allow 5ms for the shutdown internal reference
and/or buffer to wake and stabilize before starting a
conversion. In external reference mode (or if the inter-
nal reference is already on), no reference settling time
is needed after power-up.
