SCA610-E23H1A SINGLE AXIS ACCELEROMETER WITH ANALOG
INTERFACE
The SCA610 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 8 SMD legs (Gull-wing
type).
Features
 Single +5 V supply
 Current consumption 2.5 mA typical
 Ratiometric output in relation to supply
voltage (Vdd = 4.75 V...5.25 V)
 Enhanced failure detection features
o Digitally activated, true self-test by
proof mass deflection using
electrostatic force
o Memory parity check during power
up, and self-test cycle.
o Built in connection failure detection
 Digitally activated, true self-test by proof
mass deflection using electrostatic force
 Wide load drive capability (max. 20 nF)
 True DC response
 Qualified according to AEC-Q100 standard
Applications
