cLite™ Capacitive Sensor Signal Conditioner
Brief Description
Benefits
The ZSC31210 cLite™ is a CMOS integrated circuit
for accurate capacitance-to-digital conversion and
sensor-specific correction of capacitive sensor sig-
nals. Digital compensation of sensor offset, sensiti-
vity and temperature drift is accomplished via an
internal digital signal processor running a correction
algorithm with calibration coefficients stored in a
non-volatile EEPROM.
Minimized calibration costs: no laser trimming,
one-pass calibration using a digital interface
Wide capacitance range to support a broad
portfolio of different sensor elements
Excellent for low-power battery applications
Interfaces
The ZSC31210 is configurable for many capacitive
sensors with capacitances up to 260pF and a sensi-
tivity of 125aF/LSB to 1pF/LSB depending on resolu-
tion, speed, and range settings (using 3-bit reference
and 3-bit offset capacitances). It is compatible with
both single capacitive sensors (both terminals must
be accessible) and differential capacitive sensors.
Measured and corrected sensor values can be
output as I2C*, SPI, PDM, or alarms.
The I2C™ interface can be used for a simple PC-
controlled calibration procedure to program a set of
calibration coefficients into an on-chip EEPROM.
The calibrated ZSC31210 and a specific sensor are
mated digitally: fast, precise, and without the cost
overhead of trimming by external devices or laser.
I²C™ or SPI interface—easy connection to a µC
PDM outputs (Filtered Analog Ratiometric) for
both capacitance and temperature
Up to two alarms that can act as full push-pull or
open-drain switches
