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.
