The MS5607-B
is a high precision pressure sensor module and includes a linear
pressure measurement element (pressure die) and an ultra low power 24
bit ΣΔ-
A/D-converter with internal factory calibrated coefficients. The main
function is to convert the uncompensated analogue voltage from the
pressure die to a 24bit digital value, as well providing a 24 bit
value for the temperature. These values can be calculated with aid of
the internal coefficients in any external processor to the real
calibrated values. The MS5607-B
provides different operations modes that allow to optimize for speed
and current consumption. A consumption of 0.9μA at one
conversion
per second (8bit) to 12.5μA (24bit) and resolution selection per
conversion enables an optimum application specific power performance
trade-offs to be realised.
The
modules communicate via a four-wire SPI or two-wire I²C
interface.
The MS5607-B
is mounted in a small QFN-package of 5.0x3.0x1.0mm³ and allows
the integration in miniaturised mobile devices without any additional
components.
The
sensing principle employed leads to very low hysteresis and high
stability of both pressure and temperature signal.
