input sampling capacitance of the ADC (4pF). Source
impedances below 100kΩ have no significant effect on
MAX1098/MAX1099 AC performance.
Internal protection diodes clamp the analog inputs to

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.

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 µP control registers. Figure 4
shows detailed serial interface timing information. See
Tables 1–4 for programming information.
