GPT261 breathing machine medical pressure transmitter

GPT261 breathing machine medical pressure transmitterProduct description
GPT261 plastic encapsulated ultra-low pressure high-precision pressure sensor. It encapsulates a high-performance MEMS pressure-sensitive chip and a special conditioning chip in a double-nozzle SOP14 case. The pressures in the two gas circuit structures refer to each other to reduce the impact of the environment on the output.

All values in this table are tested under the condition of voltage 3.3Vdc and temperature 25 ℃ if there is no special note.
Note:
(1) Divided into two forms of gauge pressure and differential pressure;
(2) Accuracy refers to the output accuracy of the product in a clean gas environment within the compensation temperature range; accuracy is determined by the linearity, repeatability and hysteresis of the product;
(3) The sensor is in a constant temperature field, and the detection accuracy of the ambient temperature;

2. Pin definition
Pin numberPin definitionNotices:
(1)Four signal ends(VDD/GND/SDA/SCL) must be powered on and powered off at the same time,to avoid incomplete data transmission,which can cause the sensor to enter the BUSY state.once the sensor is in the BUSY state, it does not process any new commands and the product output is abnormal.
(2) Filter capacitor C1 between VDD and GND can not be used;if needed,C1≤100nf.
(3) Within 30ms when the sensor is powered off, the MCU prohibits data communication with the sensor.DimensionsOrdering GuidanceOrdering Guidance
