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.
