GENERAL DESCRIPTION
The ADIS16210 iSensor® is a digital inclinometer system that
provides precise measurements for both pitch and roll angles
over a full orientation range of ±180°. It combines a MEMS tri-
axial acceleration sensor with signal processing, addressable user
registers for data collection/programming, and a SPI-compatible
serial interface. In addition, the production process includes unit
specific calibration for optimal accuracy performance. It also
offers digital temperature sensor and power supply measurements
together with configuration controls for in-system calibration,
sample rate, filtering, alarms, I/O configuration, and power
management.
The MEMS sensor elements are bound to an aluminum core for
tight platform coupling and excellent mechanical stability. An
internal clock drives the data sampling system, which eliminates
the need for an external clock source. The SPI and data buffer
structure provide convenient access to accurate sensor data and
configuration controls.
The ADIS16210 is available in a 15 mm × 24 mm × 15 mm module
that provides mounting tabs with M2-sized mounting holes and a
flexible, edge terminated connector interface. It has an extended
operating temperature range of −40°C to +125°C.

Internal Temperature
The TEMP_OUT register (Table 18) provides access to an internal
temperature measurement. Set DIN = 0x0A00 to request the
contents of this register. Use the following process to translate
the contents of TEMP_OUT into Celsius (°C):
1. Convert the 12-bit binary number into a decimal
equivalent.
2. Subtract 1278 from the decimal equivalent.
3. Multiply the result of Step 2 by −0.47.
4. Add 25 to the result of Step 3.
Table 19 provides several examples of this data format. Note that
this internal temperature measurement provides an indicator of
condition changes, not an absolute measurement of conditions
outside of the package.

Power Supply
The SUPPLY_OUT register (Table 20) provides a digital measure-
ment for the supply voltage on the VDD pins (see Table 5). Set
DIN = 0x0200 to request the contents of this register. Use the
following process to translate the contents of SUPPLY_OUT
into volts (V):
1. Convert the 16-bit binary number into a decimal
equivalent.
2. Multiply the decimal equivalent by 5.
3. Divide the result of Step 2 by 32,768.
Table 21 provides several examples of this data format.
