... Range. OperatingTemperature Range2 ESD SENSITIVITY The AD2S46 features input protection circuitry consisting of large "distributed" polysilicon series resistors to dissipate both high energy discharges (Human Body Model) and fast, low energy pulses (Charged Device Model). Proper ESD precautions are strongly recommended to avoid functional damage or performance degradation ...

... BIT 16 f9 ENABLE PRINCIPLES OF OPERATION The AD2S46"series operate on a Type 2 tracking closed-loop principle. The output digital word continually tracks the posi- tion of the resolver/synchro shaft without the need for external convert commands and wait states. As the transducer moves through a position equivalent to the least significant bit weight- ing, the oUtput digital word is updated by one LSB ...

... DATA LS BYTE Figure 2. Timing Diagrams BYTE SELECT INPUT The BYTE SELECT input on the AD2S46 can be used to inter- face the converter to either an 8-bit or 16.bit microprocessor bus. To interface to a 16-bit parallel bus, the BYTE SELECT pin should be at logic HI. Thus, the most significant byte of the digital output position is at Pins (Bit 1 MSB to Bit 8, respectively) ...

... Alternatively, the angular unit of measure may be in radians, minutes of arc, LSBs, etc. KA does not define maximum acceleration, only the error due to acceleration. The maximum acceleration for which the AD2S46 will not lose track is in the order of S° about 660 revolutions/sec2. ...

... For example, the correct part number for a component to oper- ate with signal, 115 V reference synchro format inputs and yield a :i:1.3 arc minute accuracy over the -55°C to +125OC temperature range would be AD2S46TDI2. The same part pro- cessed to high reliability standards would carry the designator B, i.e., AD2S46TDl2B. ...
