STMicroelectronics has extended its range of dual-axis acceleration sensors with the introduction of two new devices housed in the tiny, lead-free LGA (land grid array) package measuring only 5 x 5 x 1,5 mm.
According to ST, the LIS2L02AL and LIS2L06AL are 2-axis ultra-compact linear accelerometers that complement its existing 'low g' accelerometers, while offering tighter offset tolerances, improved temperature drift performance, and a package whose smaller footprint and height is ideally suited to slim product applications such as mobile phones, PDAs, laptops, and PCMCIA cards. The LIS2L02AL provides a full-scale output range of ±2,0 G (typical), while the LIS2L06AL provides a dynamically selectable choice of ±2,0 G and ±6,0 G.
The new devices incorporate in a single package, both a robust dual-axis MEMS sensor and a CMOS interface chip that provides two simultaneous, realtime analog outputs: one for side-to-side (lateral) and one for forward-backward (longitudinal) directions. The sensor elements can measure both DC accelerations (static tilt) and AC accelerations with high resolution, can withstand shocks of up to 10 000 G, and incorporate a built-in self-test capability that allows the user to verify functionality of the device.
The interface chip incorporates all the multiplexer, charge amplifier, demultiplexer, sample-and-hold, and reference circuits required to provide the two analog output signals, with a typical bandwidth of 2,0 kHz. To maximise robustness and immunity against external disturbances, the complete signal processing chain uses a fully differential structure, with a final stage converting the differential signal into a single-ended one to be compatible with the external world.
Key benefits of the new devices include: very low noise and consequent high resolution of 0,3 mg (typical); a low power consumption (typically 850 μA supply current at 3,3 V); the small package; high temperature stability and low offset, which eliminate the need for calibration in most applications; and operation over -40 to 85° C temperature range. A built-in self-test facility also allows the user to verify both the mechanical and electrical parts of the device.
The LIS2L02AL and LIS2L06AL are suited for use in mobile terminals, gaming, and virtual-reality devices, free-fall detection for hard drives, inertial navigation and anti-theft systems, and a range of appliance, robotics, and other industrial applications.
