Mode Control
The MAX1303 contains one byte-wide mode-control
register. The timing diagram of Figure 14 shows how to
use the mode-control byte, and the mode-control 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 MAX1303.
Selecting the Conversion Method
The conversion method is selected using the mode-con-
trol byte (see the
Mode Control section), and the conver-
sion is initiated using a conversion start command (Table
3, and Figures 1, 2, and 3).The MAX1303 converts ana-
log signals to digital data using one of three methods:
External Clock Mode, Mode 0 (Figure 1)
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 2)
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 3)
High maximum throughput (see the
Electrical
Characteristics table)
The internal clock controls the sampling instant
User supplies one byte 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
External Clock Mode (Mode 0)
The MAX1303’s fastest maximum throughput rate is
achieved operating in external clock mode. SCLK con-
trols both the acquisition and conversion of the analog
signal, facilitating precise control over when the analog
signal is captured. The analog input sampling instant is
at the falling edge of the 14th SCLK (Figure 1).
Since SCLK drives the conversion in external clock
mode, the SCLK frequency should remain constant
while the conversion is clocked. The minimum SCLK
frequency prevents droop in the internal sampling
capacitor voltages during conversion.
SSTRB remains low in the external clock mode, and as a
result may be left unconnected if the MAX1303 will
always be used in the external clock mode.
