MODEL 3801A ACCELEROMETERSPECIFICATIONSGas Damped, DC Response
Hermetically SealedmV Output, Silicon MEMS
10,000g Over-Range Protection

The Model 3801A is a mV output piezoresistive MEMS
accelerometer in a rugged welded hermetic package. The
accelerometer incorporates mechanical stops for overrange protection up to greater than 10,000g. The model
3801A is offered in ranges from ±2 to ±2000g and is gas
damped to provide a wide frequency response. The
accelerometer is temperature compensated to provide astable output over the operating environment.
