NPA-730B-02WG

NPA Low Pressure Surface-Mount Pressure Sensor Series The NPA product series is provided in a miniature size as a cost effective solution for applications that require calibrated performance. Packaged in a SOIC14 pin surface mount, the NPA-Low Pressure Series is available in Gauge or Differential pressure ranges with either amplified analog or digital outputs. The sensor is intended for printed circuit board mounting and delivered in tape and reel form to simplify manufacturing handling. Features • Surface Mountable • Differential, Gauge, Low Pressure • 2” and 5” H2O Full Scale • Output Options: Amplified Analog, Digital Serial (14bit), Digital I2C • On chip temperature sensor in digital mode • Operating temperature range of -40 to 125°C • Total Error Band: +/-1.5% Span at 5”H2O full scale +/-2.5% Span at 2”H2O full scale Amphenol Advanced Sensors Low Pressure NPA Specifications Parameter Value Units Pressure Range 2 or 5 In H2O 498 or 1245 Pa 140 In H2O 400 in H2O Package Overpressure Maximum Overpressure Notes Electrical @ 25°C (77°F) unless otherwise stated Input Excitation 3.3 or 5.0 VDC -40 to +125 °C -40 to +257°F 0 to +60 °C +32 to +140°F -40 to +125 °C -40 to +257°F Environmental Temperature Range Operating Compensated Storage Mechanical/Package Weight ~1 grams Media Compatibility Positive differential and gage ports Media compatible with thermoset plastic, silicon, epoxy, RTV, Pyrex, and silicone gel Negative differential ports Dry gasses only Performance Parameters Units Accuracy (Total Error Band) 2 Minimum % Span Response Time ms Current Consumption mA Maximum Notes -1.5 1.5 5”H2O Full Scale -2.5 2.5 2”H2O Full Scale 2 1.2 0.5 ms Typical Typical Series Excitation Voltage Min (V) Max (V) Notes NPA-300 3.3V 3.28 3.32 NPA amplified analog NPA-500 5.0V 4.97 5.03 NPA amplified analog NPA-730 3.3V 3.28 3.32 NPA digital I2C NPA-700 5.0V 4.97 5.03 NPA digital I2C Output Option: Amplified Analog Analog Performance Parameters 5 volt Excitation Parameter Units 2 inH2O Min Max Offset Volts 0.40 Span Volts 0.60 5 inH2O Min Max 0.44 4 0.56 4 Analog Performance Parameters 3.3 volt Excitation 2 inH2O 5 inH2O Parameter Units Min Max Min Max Offset Volts 0.44 0.56 0.46 0.54 Span Volts 2.5 2.5 Typical Analog Circuits - Circuit layout same as “Ratiometric Voltage Output” Vsupply 3.3V or 5V Vsupply 5.5V to 30V J107 1 2 3 NPA 3 12 4 11 5 Vgate 10 7 2 13 Sensor 6 VSS 1 14 VDD 9 SIG 8 0.1µF Sensor 13 12 4 11 5 te 10 Vgate Vga 6 VSS Vout 14 NPA 7 VDD 9 SIG 8 0.1µF Vout Ground Ground Ratiometric Voltage Output - Standard NPA Ratiometric Voltage Output with Over-Voltage Protection - Request Required NPA Amplified Output Pinout Pin # Amplified Analog Function Notes 1 -- 2 -- 3 NC Do Not Connect 4 NC Do Not Connect 5 -- 6 VSS 7 -- 8 SIG Analog Out, Calibration Interface 9 VDD Supply Voltage 10 -- 11 NC Do Not Connect 12 NC Do Not Connect 13 -- 14 -- Ground Supply 3 Output Option: Digital I2C Parameter Units Min Typ Max Notes Digital Performance Resolution (ADC) bit 14 2 I C Slave Address Sampling Rate 0x28 kHz 2 I C Bit Rate 16383 steps 2 kbits/s 100 I2C Mode 400 Update Digital Performance Parameters 3.3 and 5 volt Excitation 2 inH2O Parameter 4 Units Offset Counts Span Counts 5 inH2O Min Max Min Max 1311 1966 1442 1835 13106 13106 Digital I2C Update Mode Output Options NPA I2C Pinout Pin # Digital I2C Function Notes 1 -- 2 -- 3 NC Do Not Connect 4 NC Do Not Connect 5 -- 6 VSS Ground Supply 7 VDD Supply Voltage 8 SDA Serial Data, Calibration Interface 9 SCL Serial Clock, Calibration Interface 10 -- 11 NC Do Not Connect 12 NC Do Not Connect 13 -- 14 -- I2C Circuit NPA Pinout 5 Barbed Design Recommended tubing size of 3/32” ID, 7/32” OD, 1/16” wall thickness (All measurements given in mm) Suggested PCB Land Pattern Package Leadframe Material: Alloy 194, NiPdAu 6 Ordering Information Model NPA Code Description 300 Analog Amplified Output, 3.3Vdc Excitation, Calibrated sensor 500 Analog Amplified Output, 5Vdc Excitation, Calibrated sensor 700 I2C - Digital output, Calibrated Sensor, 2 byte, 5Vdc Excitation 730 I2C - Digital output, Calibrated Sensor, 2 byte, 3.3Vdc Excitation Code Port Type B 2 barbed ports for Gauge and Differential pressure types Code Pressure Range 02W 2”H20 (0.5 KPa) 05W 5”H20 (1.24 KPa) Code Pressure Type G Gauge D Differential NPA • • • • - 700 B - 02W D EXAMPLE Contact NovaSensor for custom port options.
