MIS-7300 Series Intelligent Pressure Sensor Provides SPI or I²C Digital Serial Output Interface to Communicate with Microprocessors
METRODYNE's MIS-7300 is an Intelligent Pressure Sensor that consists of a MEMS piezoresistive pressure sensor and a signal conditioning ASIC. The sensor is formed in an ultra-thin 8-pin LGA package. The package dimension is 4.5x4x1.1mm. The signal conditioning ASIC is a 16-bit AD convertor with embedded 512-bit OTP memory. The sensor was calibrated and the temperature was compensated in the factory. The factors for temperature compensation were stored in OTP memory. Users can implement temperature compensation via an external micro processor. The external microprocessor reads the raw output data from MIS-7300 and does simple calculations according to the factors stored in OTP memory. Therefore using the MIS-7300 series makes it easy to get rid of bothersome calibrations and temperature compensations. MIS-7300 provides SPI or I²C digital serial output interface to communicate with microprocessors. MIS-7300 series is specially designed for low voltage and low power consumption concerned applications.
