Introduction:

The TWS661 is a new generation of high resolution pressure sensor from Tide Win Technology, Inc. It uses SPI Bus interface. The sensor module includes a high linearity pressure sensor and a low power 18 bits ΔΣ ADC with internal factory calibrated coefficients. It provides a precise digital 18 bits pressure measurement and different operation modes that allow the user to optimize for conversion speed and current consumption. Small dimension of only 10.0 mm X 10.0mm and height of only 3.5mm allow for integration devices.

 

Features:

l   Absolute type pressure measurement

l   Full Span: Normal 15 PSI

l   Integrated Temperature Sensor for temperature compensation

l   Span and offset calibrated, simplify host MCU program loading

l   SPI interface (Optional I2C slave interface) with data ready pin for simplified  host MCU communication

l   Power for Circuit (VDD):  2.8~3.6V

l   Operating pressure range:  0~15PSI (300~1100hpa)

l   Operating temperature range:  5~45℃

 

Applications:

l   Altimeter/Barometer

l   GPS/Mobile Phone/Security
