8.3 Power Supply Recommendations

The OPA817 is intended to operate on supplies ranging from 6 V to 12.6 V. OPA817 supports single-supply, split, balanced, and unbalanced bipolar supplies. When operating at supplies below 8 V, consideration must be given to the input common-mode range of the amplifier. Under these supply conditions, the common-mode must be biased appropriately for linear operation. Thus, the limit to lower supply voltage operation is the usable input voltage range for the JFET-input stage.
