ADIS16130
GENERAL DESCRIPTION
The ADIS16130 is a low noise, digital output angular rate sensor
(gyroscope) that provides an output response over the complete
dynamic range of ±250
Its industry-standard serial interface and register structure provide
ple interface that is supported by most MCU, DSP, and FPGA
a sim
platforms.
By implementing a unique design, the device provides superior
ability over variations in temperature, voltage, linear acceleration,
st
vibration, and next-level assembly. In addition, the surface-micromachining technology used to manufacture the device is the
same high volume BiMOS process used by Analog Devices, Inc.,
for its high reliability automotive sensor products.
Features include a temperature output that provides critical
info
rmation for system-level calibrations and a digital self-test
feature that exercises the mechanical structure of the sensor and
enables system-level diagnostics.
The package configuration is a 36 mm × 44 mm × 16 mm
mo
dule with a standard 24-lead connector interface.

BASIC OPERATION
The ADIS16130 produces digital angular rate (RATE) and
temperature (TEMP) data. The digital communication employs
a simple 4-wire SPI that provides access to output data and
several configuration features. A set of communication and
configuration registers govern the operation in the ADIS16130.
See
Tabl e 8 for a summary of these registers.
QUICK START
The ADIS16130 SPI operates in 8-bit segments. The first byte of
a SPI sequence goes into the COM register, which contains the
read/write control bit and the address of the target register. When
writing information into control registers, the next byte contains
the configuration information. When reading output data, the
next one to three bytes contain the contents of the register selected.
Configuration Sequence
The sequence in Table 6 provides the recommended configuration
sequence. Tabl e 2 and Figure 2 provide the timing information
r each segment of this configuration sequence.

Reading RATE Output Data
After the configuration sequence in Tab le 6 is complete, reading the
output data is very simple. The ADIS16130 converts the RATE
and TEMP data continuously. To better understand this process,
Figure 13 provides an example read sequence, and Tab l e 2 and
Figure 3 provide critical timing details for the output signal.
The first byte of the sequence uses SDI to establish a read of the
ATE output register. This is accomplished by writing 0x48 to the
R
COM register.
The most significant byte is first in the SDO sequence, followed
y the next significant, and then the least significant. When 16-bit
b
resolution is in use, only two bytes are output from the SDO during
the read sequence.

equentially, and each has a sample rate of 5.7 kSPS. The
Figure 13. The RATE and TEMP channels update
internal sample rate is not dependent on the SPI signals or read
rates. Using the data-ready signal to drive data collection helps
avoid losing data due to data collision, which is when a userdriven read cycle coincides with the internal update time. In
this case, the old data remains and the new data is lost.
If a lower sample rate meets system-level requirements, the
ta-ready signal can still be useful in facilitating SPI read
da
sequences. In this case, the data-ready signal pulses high for
approximately 26 μs before returning low and then repeats this
pattern at two times the internal sample rate. This signal can
feed a counter circuit (or firmware), which drives a processor
interrupt routine at a reduced sample rate.
Reading TEMP Output Data
Reading TEMP data requires a sequence that is very similar to
that of Figure 13, except that the initial SDI sequence must be
hanged from 0x48 to 0x4A. If the TEMP data is not used, Step 7
c
to Step 10 of the configuration sequence are not required.

The self-test function enables system-level diagnostic checks for the
entire ADIS16130 sensor/signal conditioning circuit. To activate
the self-test function, there must be a logic high signal on all

APPLICATIONS INFORMATION
ACHIEVING OPTIMAL NOISE PERFORMANCE
Several system-level considerations can have an impact on the
noise and accuracy of the ADIS16130. Understanding and
managing these factors can influence the behavior of any high
performance system.
Supply and Common Considerations
The ADIS16130 provides approximately 1.8 μF of decoupling
capacitance. This capacitance is distributed throughout the
device and should be taken into account when considering
potential noise threats on the power supply lines.
Bandwidth Setting
If C
is applied to reduce the bandwidth of the ADIS16130
OUT
response, it should be placed close to the device. Long cable
leads and PCB traces increase the risk of introducing noise into
the system.
SECOND-LEVEL ASSEMBLY
The ADIS16130 package supports two mounting approaches:
a bulkhead mount, where the interface is separate from the
attachment surface, and a PCB mount that provides the
mechanical and electrical connections on the same surface.
Figure 16 provides a suggested design for the ADIS16130’s
echanical attachment. The hole pattern shown in Figure 16
m
ca
n support either mounting approach and enables the integration
of the mating socket layout that is illustrated in
The mating socket layout uses the Samtec CLM-112-02 family of
co
nnectors. The 24 holes that are inside the pad accommodate the
pins on the ADIS16130, which can extend beyond the package
body. The stress relief provided by these holes is important for
maintaining reliability and optimal bias stability performance.
