GENERAL DESCRIPTION

The digital pressure sensors in the AMS 5935 series are high-resolution 18-bit board mount sensors

which provide pressure and temperature measurement data via an I²C / SPI interface. They are

extensively calibrated and compensated, leading

to high precision and high stability measurement

data over a wide temperature range of -25 to

85 °C. With an ultra low current consumption and a

supply voltage range of 1.7 … 3.6 V, the

AMS 5935 pressure sensors are especially suitable for battery-powered applications.

The AMS 5935 combine a micromachined, high

quality piezoresistive pressure sensing element

with signal conditioning ASIC in a ceramic dual inline package (DIP) for assembly on printed circuit

boards (PCBs). Two package variants are available: one with vertical pressure ports for hose connection and one for O-ring sealing (N-package type

for manifold mount).

Multiple pressure ranges for various pressure

types are available for the sensors in the

AMS 5935 series: differential (relative) pressure

sensors in ranges from 0 ... 2.5 mbar up to

0 ... 100 mbar and bidirectional differential pressure sensors from -1.25 ... +1.25 mbar up to

-100 ... +100 mbar.

Custom specific pressure ranges or modifications

are available on request.
