The SSP1495 (Product Brief) supports two different types of pressure sensors: capacitive and resistive bridge. As a capacitive pressure sensor (see Diagram), the SSP1495 can resolve 0.25mmHG in the absolute range of 560mmHG to 960mmG. Pressure data can be continuously streamed to the SSP1496 up to a 285Hz rate. The SSP1496 allows temperature data to be interleaved with pressure data.

The SSP1495 can be utilized for low power medical applications to measure: blood pressure (either capacitive pressure sensor or resistive bridge pressure sensor), blood temperature, venous hemoglobin oxygen saturation (SVO2), hematocrit (Hct), carboxyhemoglobin, glucose, or creatine (for renal function assessment). The SSP1495 is designed as an implantable device, with the bare silicon die measuring only 1mm x 3mm. Up to two SSP1495's can be connected in parallel. When used in this manner, one SSP1495 configures itself to measure SV02 and blood temperature, while the other SSP1495 is configured to measure blood pressure and blood temperature. Both SSP1495's utilize the TWINSTM power/data bus (Two Wire implantable INterface for Sensors). This bus allows power, commands and results to be transmitted over two wires.
