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.
