Block diagram AMS 5812

The AMS 5812 series of OEM sensors are fully signal conditioned, amplified, temperature compensated sensor in a dual in-line package (DIP) configuration with a 0,5 -4,5V/2,5 ±2V analog output und 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 are the result of a combination between the MEMS technology and a microelectronics signal conditioning ASIC.

The AMS 5812 series pressure sensors are based on a 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 fully compatible to 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 and no additional components are required for obtaining an amplified high level, calibrated pressure measurement.
