1 TCS Temperature Chip Select. Active low logic input. This input frames the serial data transfer for the temperature sensor output. 2 DOUT Data Out, Logic Output. The conversion of the ADIS16003 is provided on this output as a serial data stream. The bits are clocked out on the falling edge of the SCLK input. 3 DIN Data In, Logic Input. Data to be written into the control register of the ADIS16003 is provided on this input and is clocked into the register on the rising edge of SCLK. 4 COM Common. Reference point for all circuitry on the ADIS16003. 5, 7 NC No Connect. 6 ST Self-Test Input. Active high logic input. Simulates a nominal 0.75 g test input for diagnostic purposes. 8 YFILT Y-Channel Filter Node. Used in conjunction with an optional external capacitor to band limit the ac signal from the accelerometer. 9 XFILT X-Channel Filter Node. Used in conjunction with an optional external capacitor to band limit the ac signal from the accelerometer. 10 CS Chip Select. Active low logic input. This input provides the dual function of initiating the accelerometer conversions on the ADIS16003 and frames the serial data transfer for the accelerometer output. 11 VCC Power Supply Input. The VCC range for the ADIS16003 is from 3.0 V to 5.25 V. 12 SCLK Serial Clock, Logic Input. SCLK provides the serial clock for accessing data from the part and writing serial data to the control register. This clock input is also used as the clock source for the conversion process of the ADIS16003. Rev.
