NovaSensor P330B Piezoresistive (PRT) Pressure Sensor Die offers the same superior stability and sensitivity as larger chips, but in an extremely small footprint for invasive applications where small size is critical. It has excellent measurement accuracy, which is ideal for demanding applications with restricted dimensional profiles, such as medical catheters and IC packages. NovaSensor’s proprietary SenStable® process provides excellent long-term stability and repeatability.
When excited witha DC voltage source, the P330B produces an mV output that is proportional to applied pressure. The P330B employs a half-bridge design, which requires two external resistors to complete a full-bridge configuration. Additional components may be added to calibrate the output of the sensor.
NovaSensor P330B 压阻式（PRT）压力传感器裸片在极小尺寸内实现了与大尺寸芯片同样卓越的稳定性和灵敏度，尤其适用于对尺寸有严苛要求的侵入式医疗应用。其出色的测量精度使其成为心血管导管、集成电路封装等空间受限、要求严苛场景的理想选择。NovaSensor 专有的 SenStable® 工艺确保了优异的长期稳定性和可重复性。
P330B 采用直流电压源激励时，可产生与施加压力成比例的毫伏级输出信号。该芯片采用半桥设计，需外接两颗电阻构成全桥电路，并可通过增加额外元件对传感器输出进行校准。
