General Description
The MXC6202G/H/M/N are low cost, dual axis accelerometers fabricated on a standard, submicron CMOS process. It is a complete sensing system with on-chip mixed signal processing and integrated I2C bus, allowing the device to be connected directly to a microprocessor eliminating the need for A/D converters or timing resources. The MXC6202G/H/M/N measures acceleration with a full-scale range of +/- 2 g and a sensitivity of 512counts/g (G/M) or 128counts/g (H/N) @3.0 V at 25°. It can measure both dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity). The MXC6202G/H/M/N design is based on heat convection and requires no solid proof mass.
This design eliminates the stiction problems associated with legacy technologies and provides shock survival greater than 50,000g's. Memsic's solid state design leads to significantly lower failure rates in customer applications and lower loss due to handling during manufacturing and assembly processes
The MXC6202G/H/M/N is packaged in a hermetically sealed, low profile LCC surface mount package (5 mm x 5 mm x 1.55 mm) and is available in operating temperature ranges of 0° to +70° (G/H) and-40° to +85° (M/N).
The MXC6202G/H/M/N provides two I2C digital outputs with 400 KHz, fast mode operation.
The maximum noise floor is 1 mg/
allowing signals below 1 milli-g to be resolved at 1 Hz bandwidth.
