AMS 6832 – Tiny Analog-Digital Solution for Differential Pressure Measurement

In addition to its ratiometric analog output, the low-pressure sensor provides a digital I²C interface with 24-bit resolution for maximum precision. Via this channel, the AMS 6832 can transmit not only its low-noise pressure readings, but also the temperature measured directly at the membrane to virtually any available microcontroller.

The compact sensor in a robust DIL-6 package for PCB mounting is based on a piezoresistive silicon pressure cell paired with a state-of-the-art signal processing ASIC. The AMS 6832 offers a total error of less than 1% (for pressures > ±5 mbar) across the temperature range of -25 to +85 °C, and half that error at room temperature, making it one of the smallest and most accurate differential pressure sensors available.

AMSYS offers this sensor for pressure ranges from ±125 Pa up to 100 mbar, covering various bi- and unidirectional differential and relative pressures. Customer-specific adaptations are possible. To support rapid prototyping, AMSYS GmbH provides a USB starter kit for initial setup as well as a dedicated team of consultants.
