Mode Control
The MAX1032/MAX1033 contain one byte-wide mode-
control register. The timing diagram of Figure 15 shows
how to use the mode-control byte, and the mode-con-
trol byte format is shown in Table 7. The mode-control
byte is used to select the conversion method and to
control the power modes of the MAX1032/MAX1033.
Selecting the Conversion Method
The conversion method is selected using the mode-
control byte (see the
Mode Control section), and the con-
version is initiated using a conversion-start command
(Table 3, and Figures 2, 3, and 4).The MAX1032/
MAX1033 convert analog signals to digital data using one
of three methods:
External Clock Mode, Mode 0 (Figure 2)
Highest maximum throughput (see the
Electrical
Characteristics table)
User controls the sample instant
CS remains low during the conversion
User supplies SCLK throughout the ADC con-
version and reads data at DOUT
External Acquisition Mode, Mode 1 (Figure 3)
Lowest maximum throughput (see the
Electrical
Characteristics table)
User controls the sample instant
User supplies two bytes of SCLK, then drives
CS high to relieve processor load while the
ADC converts
After SSTRB transitions high, the user supplies
two bytes of SCLK and reads data at DOUT
Internal Clock Mode, Mode 2 (Figure 4)
High maximum throughput (see the
Electrical
Characteristics table)
The internal clock controls the sampling instant
