MEMSIC takes on ADI with new accelerometer

Sept. 6, 2002 — MEMSIC Inc., which makes CMOS-based MEMS accelerometers/sensors, is now offering an accelerometer with sensitivity compensation over temperature that is, according to the company, pin-for-pin compatible with Analog Devices’ (ADI) 14-lead CERPAK, cutting costs up to 50 percent and shortening lead times.

A dual axis accelerometer fabricated on a standard, submicron CMOS process, MEMSIC’s pin-for-pin compatible accelerometer provides shock survivability of 50,000 g — significantly lowering failure rates in the field — and eliminates stiction issues because it has no moving parts, the company said in a news release.

In addition, it said, the new accelerometer has a tighter initial offset, a tighter initial sensitivity error, and is factory programmable at the end of the manufacturing cycle, cutting costs to as much as 50 percent less than competitors.
