The ADIS16480 iSensor® device is a complete inertial system
that includes a triaxial gyroscope, a triaxial accelerometer, triaxial
magnetometer, pressure sensor, and an extended Kalman filter
(EKF) for dynamic orientation sensing. Each inertial sensor in
the ADIS16480 combines industry-leading iMEMS® technology
with signal conditioning that optimizes dynamic performance.
The factory calibration characterizes each sensor for sensitivity,
bias, alignment, and linear acceleration (gyroscope bias). As a
result, each sensor has its own dynamic compensation formulas
that provide accurate sensor measurements. The sensors are
further correlated and processed in the extended Kalman filter,
which provides both automatic adaptive filtering, as well as
user-programmable tuning. Thus, in addition to the IMU
outputs, the device provides stable quaternion, Euler, and
rotation matrix outputs in the local navigation frame.
The ADIS16480 provides a simple, cost-effective method for
integrating accurate, multiaxis inertial sensing into industrial
systems, especially when compared with the complexity and
investment associated with discrete designs. All necessary motion
testing and calibration are part of the production process at
the factory, greatly reducing system integration time. Tight

navigation systems. The SPI and register structure provide a
simple interface for data collection and configuration control.
Single-supply operation: 3.0 V to 3.6 V

The ADIS16480 uses the same footprint and connector system as
the ADIS16488, which greatly simplifies the upgrade process. It

1 Accuracy specifications assume calibration of accelerometers and magnetometers to address sensor drift and local influences on magnetic fields.
2 The relative error assumes that the initial error, at 25°C, is corrected in the end application.
3 Linearity errors assume a full scale (FS) of 1000 mbar.
4 The digital I/O signals are driven by an internal 3.3 V supply, and the inputs are 5 V tolerant.
5 Endurance is qualified as per JEDEC Standard 22, Method A117, and measured at −40°C, +25°C, +85°C, and +125°C.
6 The data retention specification assumes a junction temperature (TJ) of 85°C as per JEDEC Standard 22, Method A117. Data retention lifetime decreases with TJ.
7 These times do not include thermal settling, internal filter response times, or EKF start-up times (~825 ms), which may affect overall accuracy, with respect to time.
8 The device functions at clock rates below 0.7 kHz, but at reduced performance levels.
9 Supply current transients can reach 450 mA for 400 µs during start-up and reset recovery.

SPI COMMUNICATION
The SPI port supports full duplex communication, as shown in
Figure 17, which enables external processors to write to DIN
while reading DOUT, if the previous command was a read
request. Figure 17 provides a guideline for the bit coding on
both DIN and DOUT.
DEVICE CONFIGURATION
The SPI provides write access to the control registers, one byte at
a time, using the bit assignments shown in Figure 17. Each register
has 16 bits, where Bits[7:0] represent the lower address (listed in
Table 9) and Bits[15:8] represent the upper address. Write to the
lower byte of a register first, followed by a write to its upper
byte. The only register that changes with a single write to its
lower byte is the PAGE_ID register. For a write command, the
first bit in the DIN sequence is set to 1. Address Bits[A6:A0]
represent the target address, and Data Command
Bits[DC7:DC0] represent the data being written to the location.
Figure 13 provides an example of writing 0x03 to Address 0x00
(PAGE_ID [7:0]), using DIN = 0x8003. This write command
activates the control page for SPI access.

Figure 13. SPI Sequence for Activating the Control Page (DIN = 0x8003)
Dual Memory Structure
Writing configuration data to a control register updates its SRAM
contents, which are volatile. After optimizing each relevant control
register setting in a system, use the manual flash update command,
which is located in GLOB_CMD[3] on Page 3 of the register map.
Activate the manual flash update command by turning to Page 3
(DIN = 0x8003) and setting GLOB_CMD[3] = 1 (DIN = 0x8208,
then DIN = 0x8300). Make sure that the power supply is within
specification for the entire 1100 ms processing time for a flash
memory update. Table 9 provides a memory map for all of
the user registers, which includes a column of flash backup
information. A yes in this column indicates that a register
has a mirror location in flash and, when backed up properly,
automatically restores itself during startup or after a reset.
Figure 14 provides a diagram of the dual memory structure
used to manage operation and store critical user settings.

READING SENSOR DATA
The ADIS16480 automatically starts up and activates Page 0 for
data register access. Write 0x00 to the PAGE_ID register (DIN =
0x8000) to activate Page 0 for data access after accessing any other
page. A single register read requires two 16-bit SPI cycles. The
first cycle requests the contents of a register using the bit assignments
in Figure 17, and then the register contents follow DOUT during
the second sequence. The first bit in a DIN command is zero,
followed by either the upper or lower address for the register.
The last eight bits are don’t care, but the SPI requires the full set
of 16 SCLKs to receive the request. Figure 15 includes two register
reads in succession, which starts with DIN = 0x1A00 to request
the contents of the Z_GYRO_OUT register and follows with
0x1800 to request the contents of the Z_GYRO_LOW register.

Figure 15. SPI Read Example
Figure 16 provides an example of the four SPI signals when reading
PROD_ID in a repeating pattern. This is a good pattern to use
for troubleshooting the SPI interface setup and communications
because the contents of PROD_ID are predefined and stable.

NOTES
1. DOUT BITS ARE PRODUCED ONLY WHEN THE PREVIOUS 16-BIT DIN SEQUENCE STARTS WITH R/W = 0.
2. WHEN CS IS HIGH, DOUT IS IN A THREE-STATE, HIGH IMPEDANCE MODE, WHICH ALLOWS MULTIFUNCTIONAL USE OF THE LINE
FOR OTHER DEVICES.
