Silicon Designs has launched its new Model 1525 Low-G Series of MEMS DC accelerometer chips, which are designed to provide reliable, accurate, and repeatable low-frequency vibration and acceleration measurements for a variety of applications such as industrial-grade drones and robotics.
The Model 1525 Low-G Series features excellent in-run bias stability, zero cross-coupling by design, and Allan Variances from 5 µg. With availability in five unique full-scale ranges, each MEMS DC accelerometer chip within the Model 1525 Low-G Series incorporates one of Silicon Designs’ own high-performance sense elements, together with a ±4.0V differential analog output stage, internal temperature sensor, and integral sense amplifier. The MEMS DC sense element and internal components of the Model 1525 Low-G Series are housed together within a hermetically sealed, nitrogen damped, 20-pin JLCC surface mount package that measures 0.35 square inches.
Each chip in the Model 1525 Low-G Series is designed to be relatively insensitive to wide temperature changes and gradients, including over its standard operating temperature range of -40° C to +85° C. Each device is also marked on its top and bottom surfaces with a serial number for traceability. A calibration test sheet is also supplied with each unit, showing the MEMS DC accelerometer chip’s measured bias, scale factor, linearity, operating current, and frequency response performance values.
