AMS 5812 – pressure sensor with analog & digital output

AMS 5812 pressure sensor with analog and digital output

Block diagram AMS 5812

The AMS 5812 series of OEM sensors are fully signal conditioned, amplified, temperature compensated sensors in a dual in-line package (DIP) configuration with a 0.5 – 4.5V/2.5 ±2V analog output and an I²C-interface.

The AMS 5812 are calibrated and compensated in the temperature range of -25 – 85°C. High precision, high stability, and low drift result from a combination of MEMS technology and a microelectronics signal conditioning ASIC.

The AMS 5812 series pressure sensors are based on highly stable, piezoresistive pressure sensor chips mounted on a ceramic substrate. The electronically programmable ASIC is contained in the same package to provide calibration and temperature compensation. The AMS 5812 is a successor to the SM5852 with a more modern ASIC and is fully compatible with its predecessor.

Combining the sensor and the signal conditioning circuitry in a single package simplifies the use of advanced silicon micro-machined pressure sensors. The pressure sensor 0.6×0.6 inch² can be directly mounted to a standard printed circuit board, requiring no additional components for obtaining an amplified high-level, calibrated pressure measurement.
