Silicon Designs – New low-cost triaxial MEMS capacitive accelerometer modules (2445)

Silicon Designs – Designed to support a variety of low to medium-frequency triaxial measurement requirements, the 2445 Series of single-ended low-noise analog MEMS capacitive accelerometer modules has been introduced by Silicon Designs.

The rugged design of the model 2445 features three orthogonally mounted low-noise MEMS capacitive sensing elements, packaged in a nitrogen-damped, epoxy sealed lightweight aluminium housing, finished with a ±5V single ended outputs referenced to external ground.

Units are available with individual standard measurement ranges from ±2g to ±400g, with all designed for reliable operation over a temperature range of -55C to +125C. Non-standard units with enhanced measurement and temperature ranges, as well as alternative housings and outputs, are available upon request. The model 2445 features a six-wire connection with an instrumentation amplifier on each axis, for higher drive capability and low-impedance output. Both on-board voltage regulation and an internal voltage reference eliminate the need for precision power supplies and help ensure low power consumption. In addition, the model 2445 is relatively insensitive to temperature changes and gradients. Units respond to both DC and AC acceleration, says the company.

Silicon Designs rolls out ±5-g MEMS accelerometer

Silicon Designs Inc. – Joining Silicon Designs’ 2210 series of single-axis accelerometer modules is a ±5-g model intended to support a variety of lower-frequency aerospace, automotive, defense, industrial, and general test and measurement requirements. The 2210-005 incorporates MEMS capacitive sensing elements packaged within a lightweight anodized epoxy-sealed aluminum housing that occupies a total footprint of just 1 square in.

The accelerometer has a simple four-wire connection and internal voltage regulator to minimize supply-voltage variation effects. It is relatively insensitive to temperature changes and features high-drive, low-impedance buffering to support low-frequency acceleration measurement requirements from DC to 400 Hz.

All models in the 2210 series produce two analog voltage outputs, which vary with acceleration. You can choose either 0.5-V to 4.5-V single-ended or ±4-V differential output, which doubles the sensitivity over single-ended output. Differential sensitivity for the 2210-005 is 800 mV/g.

The sensitive axis is perpendicular to the bottom of the package, with positive acceleration defined as a force pushing on the bottom of the package. Signal outputs are fully differential about a common-mode voltage of approximately 2.5 V. Output scale factor is independent from the supply voltage of +9 V to +32 V.

New Kionix Gyro Sets Low-Power Benchmark for Consumer-Grade Devices

Kionix, Inc., a global leader in MEMS inertial sensor design and manufacturing, today announced its second-generation gyro, the KGY23—a 3-axis, 4 x 4 x 0.9mm sensor that features low power, low noise, flexible output ranges, and excellent bias stability over temperature.
Aimed at the consumer market, the KGY23 features:

  • Operating current consumption of 3.75 mA, a 40% decrease over its predecessor gyro, the KGY13;
  • A wide, user-programmable, full-scale range of ±256, ±512, ±1024, and ±2048 °/sec;
  • I2C or SPI digital serial interface bus communication;
  • Noise density of .30 deg/sec/√Hz, an impressively sharp 77% decrease over previous performance figures of the KGY13;
  • User-definable bandwidth via a control register of 10, 20, 40, 160 Hz;
  • An embedded temperature sensor that ensures a fast 50ms power-up time;
  • An internal 1024 byte FIFO buffer to accumulate data and efficiently transmit it to the customers’ external applications processor; and
  • Access to supply voltages between 2.6V and 3.3V and digital communication voltages between 1.8V and 3.3V.

“The improved KGY23 is the result of our engineering depth and experience coupled with fantastic customer feedback,” said Scott Miller, vice president of engineering, Kionix. “As the industry pushes for smaller MEMS sensor products, Kionix is meeting the challenge to shrink device package size while elevating performance.”
The MEMS tri-axis gyroscope market will see extraordinary growth in the coming months as more consumer products require its capabilities for applications such as user interface, gaming and navigation. According to Richard Dixon, principal analyst, MEMS & Sensors, IHS iSuppli, “Revenue for the tri-axis gyro will nearly triple in 2011, reaching $420 million in 2011, up from $127 million in 2010. Smartphones are helping to drive this impressive growth. 29% will include a gyroscope, up from just 13% last year.”
Dixon added that gyroscopes will generate the second-highest revenue among consumer and mobile MEMS in 2011, second only to accelerometers.
With the KGY23, Kionix is well positioned to take advantage of the growing demand for the next generation of sensor applications.
