    General Description
    The MAX11800–MAX11803 low-power touch-screen con-
    trollers operate from a single supply of 1.70V to 3.6V, tar-
    geting power-sensitive applications such as handheld
    equipment. The devices contain a 12-bit SAR ADC and a
    multiplexer to interface with a resistive touch-screen
    panel. A digital serial interface provides communications.
    The MAX11800–MAX11803 include digital preprocessing
    of the touch-screen measurements, reducing bus loading
    and application-processor resource requirements. The
    included smart interrupt function generator greatly
    reduces the frequency of interrupt servicing to the
    devices. The MAX11800–MAX11803 enter low-power
    modes automatically between conversions to save power,
    making the devices ideal for portable applications.
    The MAX11800/MAX11801 offer two modes of operation:
    direct and autonomous. Direct mode allows the applica-
    tion processor to control all touch-screen controller activ-
    ity. Autonomous mode allows the MAX11800/MAX11801
    to control touch-screen activity, thereby freeing the
    application processor to perform other functions. In
    autonomous mode, the devices periodically scan the
    touch screen for touch events without requiring host-
    processor intervention. This can be used to reduce sys-
    tem power consumption. An on-chip FIFO is used during
    autonomous mode to store results, increasing effective
    data throughput and lower system power.
    The MAX11800–MAX11803 support data-tagging,
    which records the type of measurement performed; X,
    Y, Z1, or Z2, and the type of touch event; initial touch,
    continuing touch, or touch release.
    The MAX11800/MAX11802 support the SPI serial bus.
    The MAX11801/MAX11803 support the I2C serial bus.
    The MAX11800–MAX11803 are available in 12-pin TQFN
    and 12-pin WLP packages, and are specified over the
    -40°C to +85°C (extended) and -40°C to +105°C (auto-
    motive) temperature ranges.
