Digital pulse density output MEMS VC accelerometers measure vibration, acceleration

SILICON DESIGNS Model 1410 family of digital pulse density output MEMS variable capacitive (VC) accelerometers reliably measure both vibration and acceleration, with very low power consumption and high long-term bias stability (1000 PPM typical). Product is suitalbe for use within low current applications consuming only 2mA with 5 volts excitation. Device uses a clock frequency between 100KHz and 1.0MHz and produces a pulse density output relative to acceleration. Units are available in seven unique standard ranges, from ±2g to ±200g, with sensitivities from 0.625 kHz/g (200 g range) to 62.5 kHz/g (2 g range). Frequency response is from 0 to 400 Hz (±2 g) up to 0 to 2000 Hz (±200 g) at fixed intervals according to selected g range.
