GENERAL DEscriptION
AMS 6915 is a series of high-precision OEM pressure sensors with a digital I²C-interface in a compact DIL package for assembly on printed circuit boards (PCBs). The series is especially suitable for low and medium differential pressure measurements in applications, which require a consequent miniaturization.
AMS 6915 sensors combine a micromachined, high quality piezoresistive measuring cell with a modern, mixed-signal signal conditioning ASIC on a ceramic substrate. The sensors are calibrated and temperature compensated and have an operating temperature range of -25 .. 85 °C. With a supply voltage of 3.3 V (5 V optional) the AMS 6915 sensors are ideal for microcontroller applications.
The sensors in the AMS 6915 series are available for various applications and pressure ranges: differential devices in pressure ranges from 0 .. 5 mbar up to 0 .. 1 bar, relative sensors for 0 .. 25 mbar up to 0 .. 1 bar, an absolute pressure variant for 0 .. 1 bar and a barometric type. Bidirectional differential devices are available in pressure ranges from -2.5 .. +2.5 mbar up to -1 .. +1 bar. Custom specific pressure ranges or further modifications are available on request.
TYPICAL APPLICATIONS
• Static and dynamic pressure measurement
• Industrial process control
• Medical instrumentation
• Heating, Ventilation and Air Conditioning (HVAC)
