Product Brief 2009 Pressure Sensors for Barometric Measurements in Consumer Applications The ASB1200V and T5300 pressure sensors are the world’s most compact, fully functional and packaged SMT barometric transmitters. They are optimized for absolute pressure measurements of 300 to 1200 mbar. The ASB1200V1 and ASB1200VR sensors are gel-protected barometric pressure transmitters with a calibrated interface. They are designed for low voltage applications. The heart of the new ASB1200V sensors is a piezoresistive sensor chip, which is mounted in hybrid technology together with the semiconductor ASIC. The ASB1200V1 provides an analog output voltage of 0 to 1 V, while the ASB1200VR delivers a ratiometric output voltage. The ASB1200V sensor’s package features a gel-protected stainless steel pressure port, which is suitable for the integration in IP64 applications. Potential applications for the pressure sensors include cameras with altimeter function, cycling computers, gas analyzers and meters, or HVAC systems in buildings. Digital interfaces with a resolution of 14 bits are in development. The T5300 digital pressure transmitter in CSMP® (chip-sized MEMS package) technology is the world’s most compact packaged sensor of its kind. It provides a 14 bit resolution at the serial digital interface. Together with a GPS-determined location, the altitude measurement permits precise 3D positioning. Applications include navigation devices with 3D maps. Moreover, it also enables position information accurate to within a single story of a building for emergency calls from mobile phones. www.epcos.com Technical Data ASB1200V1/ASB1200VR in SMD package T5300 in CSMP® technology Characteristics Pressure measurement Absolute Absolute Absolute Measurement media Output signal Pressure from Construction / type Inert moist gases 0…1V Front side ASB1200V1 Inert moist gases Ratiometric Front side ASB1200VR Inert gases Serial bus Back side T5300 4x4 2.5 3.5 4x4 2.5 3.5 2.2 x 2.6 0.9 – 300 ... 1200 -40 ... +125 -40 … +85 2.7 … 5.5 300 ... 1200 -40 ... +125 -40 ... +85 2.7 … 5.5 300 ... 1200 -40 ... +125 -40 ... +85 2.7 ... 5.5 11 DAC – Analog 0 ... 1 V 260; 10 s Upon request 11 DAC – 10 … 90% ratiometric 260; 10 s Upon request 14 bit 11 I2C, SPI 260; 10 s Upon request Dimensions Chip size / footprint Total height (max.)
