Description
Product Description
MS5540C is an SMD hybrid device including high-precision piezoresistive pressure sensor and ADC interface IC. It is a miniature version of the MS5534C barometer/altimeter module, and it provides 16-bit pressure and temperature parameters depending on the voltage. MS5540C is a low-voltage, low-power device with automatic power-off switch. The 3-wire interface can satisfy various communication with the microprocessor. Compared with MS5534A, the pressure range is improved (measurement dropped to 10 mbar). Compared with MS5534B, MS5540B has been upgraded from 15-bit output to 16-bit digital output. Other improvements include ESD sensitivity, current consumption and converter accuracy. MS5540C software is compatible with MS5534A, MS5534B, MS5534C, MS5540B. In addition, MS5540C is compatible from its external dimension to the MS54xx series of pressure sensors. The glue protection of the sensor can satisfy the use of waterproof watches at a depth of 100 meters without any other protection. application: *Portable altimeter/barometer system *Weather control system *Field adventure or multi-mode watch *Backup current
