The SiFlexTM SF1600S.A and SF1600SN.a products combine a MEMS capacitive accelerometer, based on a bulk micro-machined
silicon element in a ceramic package attached through an interconnect board to a custom mixed-signal ASIC to enable analog closedloop
force-feedback operation of the accelerometer. The multi-chip module (MCM) assembly is mounted to a printed circuit board
consisting of power conditioning electronics employing linear regulators, output amplifiers and other support electronics.
The SF1600 operates from a bipolar power supply voltage that can range from ± 6V to ± 15V with a typical current consumption of
11mA at ± 6V. The linear full acceleration range is ± 3g with a corresponding sensitivity of 1.2V/g. It can operate over a wide
temperature range from -40°C to +85°C and can withstand a shock of up to 1500g without performance degradation. The frequency
response over the full scale range is DC to > 1500Hz.
The product is available with oscillator (SF1600S.A) or without oscillator (SF1600SN.A).
