DATASHEET AMS 5812 SERIES
Board Mount Pressure Sensor with Analog and I2C Output
FEATURES
GENERAL DESCRIPTION
The OEM pressure sensors in the AMS 5812
series are high-precision sensors with two different
outputs, an analog output and a digital I2C output.
The analog 0.5 to 4.5V output is ratiometric to the
supply voltage and provides pressure measure-
ment data only, while the I2C output provides
pressure as well as temperature measurement
data. Both outputs can be used simultaneously.
Board mount pressure sensor series with
analog voltage output and digital I2C output
Calibrated and temperature compensated
Differential/relative, bidirectional differential,
absolute and barometric sensor versions
Wide variety of pressure ranges: 0.054 psi
(1.5 inch water) up to 100 psi full scale
AMS 5812 sensors combine a micromachined,
high quality piezoresistive pressure sensing
element with a modern, signal conditioning CMOS-
ASIC on a ceramic substrate. They are extensively
calibrated and temperature compensated in a wide
temperature range of -25 to 85 °C. This enables
high precision measurements and excellent drift
and long-term stability.
Piezoresistive sensor with high precision
digital signal conditioning
Total accuracy < 0.5 %FSO at room
temperature for standard pressure ranges
TEB < 1.0 %FSO (-25 … 85 °C) for standard
pressure ranges
The AMS 5812 pressure sensors come in a
compact and robust dual in-line ceramic 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). The sensors are operational
without any additional components.
High long term stability
Fast response time (typ. < 1 ms)
Supply voltage range: 4.75 … 5.25 V
Analog output: 0.5 to 4.5 V ratiometric
Digital output via I2C interface: 15 bit for
pressure and temperature measurement
The sensors in the AMS 5812 series are available
for all pressure types in various pressure ranges:
differential (relative) pressure sensors in ranges
from 0 … 0.054 psi up to 0 … 100 psi, absolute
pressure types for 0 … 5 psi up to 0 … 30 psi and
11 … 17.5 psi for barometric measurements.
Bidirectional differential sensors are available from
-0.054 … +0.054 psi up to -15 … +15 psi. Custom
specific pressure ranges and modifications are
available on request.
Programmable I²C-address
Ceramic DIP-8 package (width: 0.6 inch)
