SCA720-D01 SINGLE AXIS ACCELEROMETER WITH ANALOG INTERFACE
The SCA720 accelerometer consists of a silicon bulk micro machined sensing element chip and a signal
conditioning ASIC. The chips are mounted on a pre-molded package and wire bonded to appropriate contacts.
The sensing element and ASIC are protected with silicone gel and lid. The sensor has 12 SMD legs (Gull-wing
type).
