NOTE: These specifications apply over temperature range, power supply range,
reference frequency and amplitude range, ±10% signal amplitude varia-
tion, and up to ±10% harmonic distortion in reference input.
POWER SUPPLIES
The main power supplies can vary over the specified ranges with
no change in converter specifications, except for a proportional
change in maximum tracking rates.
When testing or evaluating the converters, it is advisable to limit
the current in each of the supplies. Set each current limit 50%
greater than the maximum current listed for that supply as listed
in TABLE 1.
TIMING
FIGURE 2 shows the converter timing waveforms. Whenever an
input angle change occurs, the converter changes the digital
angle in 1 LSB steps, and generates a Converter Busy (CB)
pulse. The CB is a positive pulse 0.5 to 1.5 sec long.
Data changes on the leading edge of the CB pulse, and data can
be transferred 0.5 sec after the leading edge.
