RDC-19220/2/4 Specifications
Notes:
1. Accuracy in LVDT mode is 0.15% + 1 LSB of full scale.
2. If the frequency is between 47Hz and 1kHz, then there may be 1 LSB of jitter at quadrant boundaries.
3. The maximum phase shift tolerance will degrade linearly from 45 degrees at 400 Hz to 30 degrees at 60 Hz.
4.-XX5 accuracy is 1minute + 1 LSB up to 5 kHz max.
5. See full datasheet for +5V only option details.
