Features

▪ AEC-Q100 qualified QFN24 package (4x4mm)

▪ Provides data for impedance calculation (data

proportional to in-phase and quadrature phase

components of impedance) for up to

seven measurement channels (SIO)

▪ All seven channels are equivalent, maximum

three channels can be activated at the same time.

For example, one channel is used for measuring

the impedance (DUT or reference impedance)

and up to two channels as shield

▪ Fast measurement rate with minimum 0.4ms

conversion time per channel

▪ Adjustable measurement frequency between

50kHz and 150kHz

▪ Internal and external temperature sensor

▪ Up to 16 flexible adjustable measurement schemes:

SIO input, gain, driver strength, averaging and

non-harmonic excitation frequency

▪ Scalable measurement ranges up to 3200pF

▪ High linearity: up to ±1.5%FS

▪ Sensitivity without averaging up to 5fF/LSB

▪ Supports 3.3V and 5V supply, power saving mode

▪ Supports heating and sensing on the same foil

▪ 18V over-voltage robust input channels

▪ Development process compliant with ISO26262 ASIL B

▪ Background processed data acquisition for selfsupervision

and sensor diagnostics

▪ Internal oscillator with external clock input option

▪ NVM for IC calibration and traceability data

▪ Ambient temperature range between

-40°C and 105°C
