9.1 Power Supply Recommendations

The OPA955 operates on supplies from 3.3V to 5.25V. The OPA955 operates on single-sided supplies, split and

balanced bipolar supplies, and unbalanced bipolar supplies. Because the OPA955 does not feature rail-to-rail

inputs or outputs, the input common-mode and output swing ranges are limited at 3.3V supplies.
