Please note: Except for the functional variations stated above, there also exist differences
between the proximity and touch thresholds for the IQS128L version. More on this in Sections
6.4 & 6.5.
1.2 Device
The IQS128 and IQS128L ICs will be
referred to as IQS128/IQS128L throughout
the datasheet, unless they have different
functionality, where it will be explicitly
stated and explained.
The IQS128/IQS128L is a single channel
capacitive proximity and touch device which
employs an internal voltage regulator and
reference capacitor (Cs).
The
IQS128/IQS128L
device
has
a
dedicated pin for the connection of a sense
electrode (Cx) and output pin for proximity
and touch events on OUT. The polarity of
the output pins can be configured. A 1-wire
open drain data streaming protocol is
implemented for debugging purposes.
Special device configuration can be done
by setting one time programmable (OTP)
options.
The device automatically tracks slow
varying environmental changes via various
signal processing algorithms and has an
Automatic Tuning Implementation (ATI)
algorithm to calibrate the device to the
sense electrode.
DYCAL™ (Dynamic Calibration) is a
special form of hysteresis that can track
slow varying environmental change even
while the sensor is in a touch state.
The charge transfer method of capacitive
sensing
is
employed
on
the
IQS128/IQS128L. (The charge transfer
principle is thoroughly described in the
application
note:
“AZD004

Azoteq
Capacitive Sensing”.)
1.3 Operation
The device has been designed to be used
in applications where proximity is required
and touch conditions can prevail for an
extended period of time which may result in
uncompensated
drift
in
conventional
capacitive sensors.
A low threshold is used to detect the
proximity of an object, with a higher
threshold for touch detection.
Dynamic Calibration is performed when a
TOUCH condition is detected for longer
than TDYNACAL. The hysteresis algorithm will
now check for the release condition of the
touch, while still tracking environmental
changes
1.4 Applicability
All specifications, except where specifically
mentioned otherwise, provided by this
datasheet are applicable to the following
ranges:
Temperature:-40C to +85C
Supply voltage (VDDHI): 2.95V to 5.5V
