GENERAL DESCRIPTION

The pressure sensors/switches in the AMS 5105

series combine a high-precision OEM pressure

sensor with a programmable pressure switch in

one package. AMS 5105 has one analog voltage

output and two independent logic switching

outputs. The analog voltage output is ratiometric to

the supply voltage of 5 V. The switching outputs

are software configurable as normally open,

normally closed or in window mode; thresholds and

hysteresis can be set individually. The pressure

sensors/switches are calibrated and compensated

for across a temperature range of -25 to +85°C.

AMS 5105 comes in a dual in-line package (DIP)

for assembly on printed circuit boards (PCBs). The

electrical connection is made via the DIP solder

pins; pressure is connected via two vertical metal

tubes.

AMS 5105 is available for various applications and

pressure ranges: differential (relative) devices in

ranges from 0…5 mbar up to 0…7 bar, two

absolute pressure variants for 0…1 bar and 0…2

bar and a barometric variant. Bidirectional

differential devices are available in different ranges

from -5…+5 mbar up to -1…+1 bar. Other pressure

ranges or customized modifications are available

on request.
