ST's LYPR540AH is a MEMS motion sensor, three-axis analog output gyroscope with yaw, tilt and roll analog gyroscope features, and a separate output path for the three axes. LYPR540AH provides amplification (±400 dps full scale) and no amplification ( ±1600 dps full scale) output, -3dB bandwidth detection rate up to 140 Hz, analog operating voltage 2.7 V to 3.6 V, mainly used in sports and human-machine interfaces, fitness equipment, remote controllers, industrial and robotic, personal navigation equipment. This paper introduces the main features of LYPR540AH, block diagram and application circuit diagram. This article refers to the address: http:// LYPR540AH: MEMS motion sensor: 3 axis analog output gyroscope The LYPR540AH is a three axis yaw, pitch and roll analog gyroscope featuring three separate analog output channels. LYPR540AH provides amplified (±400 dps full scale) and not amplified (±1600 dps full scale) outputs for each sensible axis available at the same time through dedicated pins, and is capable of detecting rates with a -3 dB bandwidth up to 140 Hz . ST 3 axis gyroscope family leverages on robust and mature manufacturing process already used for the production of hundreds of millions of micromachined accelerometers with excellent acceptance from the market. Sensing element is manufactured using specialized micromachining processes, while the IC interfaces are realized using a CMOS technology that allows to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The LYPR540AH is available in plastic Land Grid Array (LGA) package. Several years ago ST pioneered successfully the usage of this package for accelerometers. Today ST has the widest manufacturing capability and strongest expertise in the world for production of sensors in plastic LGA package. LYPR540AH main features: ■Analog supply voltage 2.7 V to 3.6 V ■Wide extended operating temperature range (-40°C to 85°C) ■3 indipendent angular rate channels ■±400 dps and ±1600 dps full-scale ■High shock survivability ■Embedded self-test ■ECOPACK® RoHS and “Green†compliant LYPR540AH application: ■Motion and man machine interface ■Gaming and virtual reality input devices ■Fitness and wellness ■Pointing device and remote controllers ■Industrial and robotics ■Personal navigation devices Figure 1.
