... THEORY OF OPERATION The ADIS16203 is a calibrated digital inclinometer that provides a full 360° of measurement range in any rotational plane that is parallel to the earth’s gravity. A dual-axis accelerometer provides the base-sensing function, which resolves the earth’s gravity into two orthogonal vectors, as displayed in Figure 23. A power-efficient approach to a common trigonometric identity converts these orthogonal vectors into an incline- angle measurement ...

... The ADIS16203’s SPI port includes four signals: chip select ( CS ), serial clock (SCLK), data input (DIN), and data output (DOUT). The CS line enables the ADIS16203’s SPI port and, in effect, frames each SPI event. When this signal is high, the DOUT lines are in a high impedance state and the signals on DIN and ...

... R COMMAND W CONTROL REGISTER ACCESS Table 8 displays the control register map for the ADIS16203, including address, volatile status, basic function, and accessibility (read/write). The following sections contain detailed descriptions and configurations for each of these registers. The ADIS16203 is a Flash-based device with the nonvolatile functional registers implemented as Flash registers ...

... CONTROL REGISTER DETAILS All ADIS16203 control registers are organized into 2-byte segments, and both upper (Bit 8 to Bit 15) and lower (Bit 0 to Bit 7) bytes have unique addresses and can be accessed individually. MSB D15 D14 D13 D12 D11 This section provides a description of each register, including its purpose, relevant scaling information, bit maps, addresses, and default values ...

... Another potential ROC application is to monitor slowly changing outputs in the inclination level. With the addition of the alarm hard- ware functionality, the ADIS16203 can be left to run independently of the main processor and interrupt the system only when an alarm condition occurs. Conversely, the alarm condition can be monitored through the routine polling of any one of the seven data output registers ...

... FILTERING CONTROL The ADIS16203 uses two types of filters for the output data. The INCL_OUT and INCL_180_OUT data outputs use a Bartlett Window function, and the SUPPLY_OUT, AUX_ADC, and TEMP_OUT data outputs use a standard moving-averaging filter. The number of taps set by the AVG_CNT control register establishes the frequency response ...

... The status control register within the ADIS16203 is utilized in deter- mining the present state of the device. The ability to monitor the device becomes necessary when and if the ADIS16203 has registered an alarm and/or error condition as indicated by the alarm enable (Bit 14) within the output data registers. ...

... The self-test operation exercises the base accelerometer’s mechanical structure and establishes a mechanical diagnostic test. The self-test offers the ability to have the ADIS16203 run an internal diagnostic test, which returns a pass/fail condition (see the STATUS register definition of Bit 5 in Table 19). This feature also provides the ability to observe the incline angle outputs during the self-test function, which is nominally 37° ...

... AUXILIARY DAC FUNCTION The auxiliary DAC function integrates a standard 12-bit DAC into the ADIS16203. The DAC output is buffered and fed off-chip to allow for the control of miscellaneous system-level functions. Data downloads through the writing of two adjacent data bytes as defined in its register definition ...

... GENERAL-PURPOSE I/O CONTROL As previously noted, the ADIS16203 provides two general-purpose, bidirectional I/O pins (GPIOs) that are available to the user for control of auxiliary circuits within the target application. All I/O pins are 5 V tolerant, meaning that the GPIOs support an input voltage Each GPIO pin has an internal pull-up resistor of approximately 100 kΩ ...

... ADIS16203 APPLICATIONS HARDWARE CONSIDERATIONS The ADIS16203 can be operated from a single 3 3.6 V) power supply. The ADIS16203 integrates two decoupling capacitors that are 1 μF and 0.1 μF in value. For the local operation of the ADIS16203, no additional power supply decoupling capacitance is required. However, if the system power supply presents a substantial amount of noise, additional filtering may be required ...

... An internal power-on reset (POR) is implemented internally to the ADIS16203. For VDD below 2.35 V, the internal POR holds the ADIS16203 in reset. As VDD rises above 2. internal timer times out for typically 130 ms before the part is released from reset. The user must ensure that the power supply has reached a stable 3 ...
