10 Power Supply Recommendations

The OPA2810 is intended for operation on supplies ranging from 4.75 V to 27 V. The OPA2810 may be operated on single-sided supplies, split and balanced bipolar supplies or unbalanced bipolar supplies. Operating from a single supply can have numerous advantages. With the negative supply at ground, the DC errors due to the –PSRR term can be minimized. Typically, AC performance improves slightly at 10-V operation with minimal increase in supply current. Minimize the distance (< 0.1") 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. For single-supply operation, only the positive supply has these capacitors. When a split-supply is used, use these capacitors from each supply to ground. 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.
