This Product Selection Guide contains information to help select products in the Motion Sensors - Gyroscope category on DigiKey.com
Gyroscopic motion sensor ICs and modules are used for measuring or maintaining orientation and angular velocity on one or multiple axes. Axes may include X (pitch), Y (roll) and Z (yaw) in rotation ranges from 100 to 6000 degrees. Gyroscopes (gyros) are selected by sensitivity, analog or digital, voltage supply, case style and output type such as analog, I2C and SPI.
SelectionCharacteristics
Specifications to determine which Gyroscope is right for your application.
Type: Identifies whether the device is analog or digital.
Axis: Identifies the number of orthogonal planes in 3-dimensional space for which a device provides a sensing or input capability.
Range °/s: The span(s) of angular rate inputs over which a device can produce a valid measurement thereof.
Sensitivity:
Digital (LSB/(o/s)) - The typical change in output code (# of Least Significant Bits) for a 1o/second change in angular rate input around the sensed axis.
Analog (mV/o/s) - The typical change in output voltage for a 1o/second change in angular rate input around the sensed axis.
Bandwidth: The frequency range over which the device is designed to operate.
Output Type: Indicates the type of electrical signal the device provides, such as voltage or I2C.
Available Output Types
Analog Voltage
The output signal of the device is in volts.
I2C (Inter-Integrated Circuit)
The output signal of the device is compatible with I2C interface protocols, enabling it to communicate with other I2C enabled devices. An I2C signal is uses a synchronous, bi-directional, two wire serial interface.
I2C, SPI
The output signal of the device can be an I2C and/or SPI signal.
SPI (Serial Peripheral Interface)
The output signal of the device is compatible with SPI interface protocols, enabling it to communicate with other SPI enabled devices. SPI signals use separate lines for data and clock transmission allowing for synchronous data transmission.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Current - Supply: This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damge the device and/or other system components.
Features: These are different capabilities of the device such as adjustable bandwidth and sleep mode.
Available Features
Adjustable Bandwidth
The bandwidth the device operates on can be adjusted by the user.
Selectabel Scale
The range that the device can measure can be adjusted by the user.
Sleep Mode
The device can enter a low power mode when certain criteria are met. This reduces overall power consumption of the device.
Temperature Compensated
Includes other circuitry that compensates for changing temperatures. Changing temperatures can affect output readings if they are not compensated. This causes errors in calculations that can be quite substantial.
Temperature Sensor
The device has a temperature sensor incorporated into it.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Package/Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
