ICP-20100
High Accuracy, Low Power, Barometric Pressure
and Temperature Sensor IC
GENERAL INFORMATION
FEATURES
The ICP-20100 pressure sensor provides a high-accuracy, low
power, barometric pressure and temperature sensor solution,
that integrates a capacitive pressure sensor for monitoring
pressure changes in the range of 30 to 110 kPa.
•
•
•
Digital-output pressure and temperature sensors,
with programmable output: all-pressure, all-
temperature or pressure & temperature
Programmable noise performance down to
0.5 Parms through programmable Oversampling
Ratio (OSR)
The ICP-20100 integrates a DSP module for on-chip
calibration with an Analog-to-Digital converter (ADC), digital
filtering, a FIFO and has I²C, I3CSM, and SPI interfaces
available. The solution can be configured to achieve ultra-low
noise or ultra-low power performance and is flexible to
perform anywhere in-between. Additionally, the filters can be
enabled to allow even lower noise performance or activate
features such as filtering of pressure glitches (e.g.
opening/closing a window).
Digital filtering for pressure signals
o
Finite Impulse Response (FIR) filter for
improved noise performance
o
Infinite Impulse Response (IIR) filter for e.g.
filtering of pressure glitches
