EVALUATION TOOLS

Breakout Board, ADIS16IMU1/PCBZ

The ADIS16IMU1/PCBZ (sold separately) provides a breakout

board function for the ADIS16486, providing access to the

ADIS16486 through larger connectors that support standard

1 mm ribbon cabling. This breakout board also provides four

mounting holes for attaching the ADIS16486 to the breakout

board. See the Ordering Guide for ordering details.

PC-Based Evaluation, EVAL-ADIS2

The EVAL-ADIS2 provides the system support PC-based

evaluation of the ADIS16486.

POWER SUPPLY CONSIDERATIONS

The VDD power supply must charge 24 µF of capacitance (inside

of the ADIS16486, across the VDD pins and GND pins) during

the initial ramp and settling process of the power supply. When

VDD reaches 2.85 V, the ADIS16486 begins its internal start-up

process, which generates additional transient current demand.

See Figure 34 for a typical current profile during the start-up

process. The first peak in Figure 34 relates to charging the 24 µF

capacitor bank, whereas the second peak (~360 ms after the first

peak) relates to the initialization process of the ADIS16486. See

Figure 35 for a close view of the current profile associated with

the second peak in Figure 34.

X-RAY SENSITIVITY

Exposure to high dose rate X-rays, such as those in production

systems that inspect solder joints in electronic assemblies, can

affect accelerometer bias errors. For optimal performance,

avoid exposing the ADIS16486 to this type of inspection.
