# Measuring unit ADIS of inertia

ADIS16355 is a digital output, all warm calibrated __ high__ performance, little inertial measurement

__which U.S.A. ADI Company put out newly. The output is SPI serial interface, offer three angle speed signals, three linear accelerometer signals,__

**system**__sensor signal, mains__

**temperature**__signal__

**voltage**__an auxiliary analog input. Factory troposphere lean towards and degree of sensitivity go on all warm accurate to normalize.__

**and**First. Characteristic:

1.Volume only 23mm *23mm *23mm!

2.Factory to degree of sensitivity, zero lean towards and installation error go on all warm to normalize ' From -40 Â¡Ã¦ +85 Â¡Ã¦)

3.The angle speed measurement limits of three axles: 75 degrees of Â¡Ã€ / s, 150 degrees of Â¡Ã€ / s, 300 degrees of Â¡Ã€ / s (can be presumed through the procedure)

Definition: 14

4.The measurement limits of acceleration of three axles: Â¡Ã€ 10g

Definition: 14

5.Bandwidth: 350Hz (can presume other arbitrary bandwidth values through the procedure)

6.Embedded temperature sensor

7.SPI serial interface export

8.12 auxiliary ADCs input and 12 DACs export

9.Zero of digital __ control__ is simply normalized

10.Numerically controlled sampling rate

11.Digital control is filtered

12.The figure encourages the self-checking function

13.Programmable to call the police

14.Programmable __ power__ management

15.Auxiliary digital I/O interface

16.Service voltage: 5VÂ¡Ã€ 5%

17.Bear and assault the acceleration: 2000g (under energization situation)

Two. Typical application:

Navigation and controlling of the vehicle

The platform is stabilized and controlled

Motion control and analysis

GPS assists and navigates

It is steady to make a video recording

Robot

Three. IMU performance parameter:

(Condition: Temperature =-From 40 Â¡Ã¦ to +85 Â¡Ã¦; Vcc =5V; Angle speed =0 degrees / s; Dynamic range =300 degrees of Â¡Ã€ / s, Â¡Ã€ 1g)
