FXPS7400D4 Datasheet | NXP Semiconductors

description The FXPS7400D4 high-performance, high-precision barometric absolute pressure (BAP) sensor consists of a pact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital integrated circuit (IC) producing a fully calibrated digital output. The sensor is based on NXP's high-precision capacitive pressure cell technology. The architecture benefits from redundant pressure transducers as an expanded quality measure. This sensor delivers highly accurate pressure and temperature readings through either a serial peripheral interface (SPI) or an inter-integrated circuit (I2C) interface. Furthermore, the sensor employs an on-demand digital self-test for the digital IC and the MEMS transducers. The sensor operates over a pressure range of 20 k Pa to 400 k Pa and over a wide temperature range of - 40 ºC to 130 ºC. The sensor es in an industry-leading 4 mm x 4 mm x 1.98 mm, restriction of hazardous substances (Ro HS) pliant, high power quad flat no lead (HQFN) package[1] suitable for small PCB integration. Its AEC-Q100[2] pliance, high accuracy, reliable performance, and high media resistivity make it ideal for use in automotive, industrial, and consumer applications. 2 Features and benefits - Absolute pressure range: 20 k Pa to 400 k Pa - Operating temperature range: - 40 °C to 130 °C - Pressure transducer and digital signal processor (DSP) - Digital self-test - I2C patible serial interface - Client mode operation - Standard mode, Fast mode, and Fast-mode Plus support - 32-bit SPI patible serial interface - Sensor data transmission mands - 12-bit data for absolute pressure - 8-bit data for temperature - 2-bit basic status and 2-bit detailed status fields - 3, 4, or 8-bit configurable CRC - Capacitance to voltage converter with anti-aliasing filter - Sigma delta ADC plus sinc filter - 800 Hz or 1000 Hz low-pass filter for absolute pressure - Lead-free, 16-pin HQFN, 4 mm x 4 mm x 1.98 mm package NXP Semiconductors Digital absolute pressure...
