input sampling capacitance of the ADC (4pF). Source
impedances below 100k
have no significant effect on
MAX1098/MAX1099 AC performance.
Analog Input Protection
Internal protection diodes clamp the analog inputs to
VDD and GND so channels can swing within GND -
0.3V and VDD + 0.3V without damage. However, for
accurate conversions, the inputs should not extend
beyond the supply rails.
If an off-channel analog input extends beyond the
supply rails, limit the input current to 2mA.
Serial Digital Interface
The MAX1098/MAX1099 feature a serial interface that is
fully compatible with SPI, QSPI, and MICROWIRE
devices. For SPI/QSPI, ensure that the CPU serial inter-
face runs in master mode so it generates the serial
clock signal. Select a 2.5MHz clock frequency or less,
and set zero values for clock polarity (CPOL) and
phase (CPHA) in the P control registers. Figure 4
shows detailed serial interface timing information. See
Tables 1–4 for programming information.
