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 measurement data only, while the I2C output provides

pressure as well as temperature measurement

data. Both outputs can be used simultaneously.

AMS 5812 sensors combine a micromachined,

high quality piezoresistive pressure sensing

element with a modern, signal conditioning CMOSASIC 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.

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.

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.
