GENERAL DESCRIPTION
The IDG-300 is an integrated dual-axis angular rate
sensor (gyroscope). It uses InvenSense’s proprietary and
patented MEMS technology with vertically driven,
vibrating masses to make a functionally complete, lowcost,
dual-axis angular rate sensor. All required
electronics are integrated onto a single chip with the
sensor.
The IDG-300 gyro uses two sensor elements with novel
vibrating dual-mass bulk silicon configurations that sense
the rate of rotation about the X- and Y-axis (in-plane
sensing). This results in a unique, integrated dual-axis
gyro with guaranteed-by-design vibration rejection and
high cross-axis isolation. It is specifically designed for
demanding consumer applications requiring low cost,
small size and high performance.
The IDG-300 gyro includes integrated electronics
necessary for application-ready functionality. It
incorporates X- and Y-axis low-pass filters and an
EEPROM for on-chip factory calibration of the sensor.
Factory trimmed scale factors eliminate the need for
external active components and end-user calibration.
This product is lead-free and Green Compliant.

DESIGN NOTES
1. Overview
The IDG-300 gyro is a dual-axis gyroscope consisting of
two independent vibratory MEMS gyroscopes. One
detects rotation about the X-axis; the other detects
rotation about the Y-axis. Each structure is fabricated
using InvenSense’s proprietary bulk silicon technology.
The structures are covered and hermetically sealed at the
wafer-level. The cover shields the gyro from EMI.
The gyroscope’s proof-masses are electrostatically
oscillated at resonance. An internal automatic gain
control circuit precisely sets the oscillation of the proof
masses. When the sensor is rotated about the X- or Yaxis,
the Coriolis effect causes a vibration that can be
detected by a capacitive pickoff. The resulting signal is
amplified, demodulated, and filtered to produce an analog
voltage that is proportional to the angular rate.
2. Amplitude Control
The scale factor of the gyroscope depends on the
amplitude of the mechanical motion and the trim setting
of the internal programmable gain stages. The oscillation
circuit precisely controls the amplitude to maintain
constant sensitivity over the temperature range. The
capacitors (0.22μF, ±10%) connected to Pin 8 (XAGC)
and Pin 23 (YAGC) are compensation capacitors for the
amplitude control loops.
5. Power Supply Filtering
The IDG-300 gyro should be isolated from system power
supply noise by a combination of an RC filter that
attenuates high frequency noise and a Low Drop Out
power supply regulator (LDO) that attenuates low
frequency noise. Figure below shows a typical
configuration.
The low-pass RC filter should be chosen such that it
provides significant attenuation of system noise at high
frequencies. The LDO should be a low noise regulator
(<100μV/rtHz) that exhibits good noise rejection at low
frequencies.
6. VREF
VREF is a temperature independent voltage reference
that can be used as a reference for an ADC. There is
offset between the zero rate output and VREF.

2.2Ω 0.1μF

En GND
VOUT

3. External Low-Pass Filter
An external low-pass filter is recommended to attenuate
high-frequency noise. The cutoff frequency should be less
than 2 kHz to attenuate tones above 10 kHz generated by
the vibrating proof-masses. Recommended RC values for
the 2 kHz filter are RLPX/RLPY and CLPX/CLPY are 750Ω and
0.1μF respectively. The sensor bandwidth is limited to 140
Hz by the internal low-pass filter. Applications that require
lower bandwidth should choose an external filter with a
cutoff frequency less than 140Hz.
4. Scale Factor
The IDG-300 Rate-Out is not ratiometric to the supply
voltage. The scale factor is calibrated at the factory and is
nominally independent of supply voltage.

见过这小轮汽动小越野车吗？这是我为浙江某公司设计秤的，出口欧美、意大利最少也有百多万台。那几年永康家家仿照生产。。。。。。http://i4.tdimg.com/113/522/097/p.jpg

這東西不難。難在誰要出原型測試。

这个车使用时，那个把手将会是最大的问题，挤占了人在车上的站立空间，应当前坚直或一定角度的前倾才行吧（ ...
