Power Supply Recommendations

The OPA2863-Q1 is intended to operate on supplies ranging from 2.7 V to 12.6 V. The OPA2863-Q1 operates on single-sided supplies, split and balanced bipolar supplies, or unbalanced bipolar supplies. Operating from a single supply has numerous advantages. The dc errors, due to the –PSRR term, can be minimized with the negative supply at ground. Typically, ac performance improves slightly at 10-V operation with minimal increase in supply current. Minimize the distance (< 0.1 in) from the power supply pins to high-frequency, 0.01-µF decoupling capacitors. A larger capacitor (2.2 µF typical) is used along with a high-frequency, 0.01-µF supply-decoupling capacitor at the device supply pins. Only the positive supply has these capacitors for single-supply operation. Use these capacitors from each supply to ground when a split-supply is used. If necessary, place the larger capacitors further from the device and share these capacitors among several devices in the same area of the printed circuit board (PCB). An optional supply decoupling capacitor across the two power supplies (for split-supply operation) reduces second harmonic distortion.
