BMB085 general description

The BMP085 is the fully pin- and function compatible successor of the SMD500, a new

generation of high precision digital pressure sensors for consumer applications. The universal

recognizes automatically the device ID. Customers already working with the SMD500 pressure

sensor are invited to contact Bosch Sensortec as soon as they intend to switch-over to the

BMP085 sensor for getting first-hand support.

The ultra-low power, low voltage electronics of the BMP085 is optimized for use in mobile

phones, PDAs, GPS navigation devices and outdoor equipment. With a low altitude noise of

merely 0.25m at fast conversion time, the BMP085 offers superior performance. The I

interface allows for easy system integration with a microcontroller.

The BMP085 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity

as well as long term stability.

Robert Bosch is the world market leader for pressure sensors in automotive applications. Based

on the experience of over 200 million pressure sensors in the field, the BMP085 continues a

new generation of micro-machined pressure sensors.
