9 Power Supply Recommendations

The OPA862 is intended to work in a supply range of 3 V to 12.6 V. The OPA862 can be used in single-supply operation, or in a balanced or unbalanced split-supply operation. Good power-supply bypassing is recommended for best AC performance and distortion in particular. Minimize the distance (less than 0.1 inch) from the power-supply pins to high-frequency, 0.1-µF decoupling capacitors. A larger capacitor (2.2 µF or 10 µF is typical) is used with a high-frequency, 0.1-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 for 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). Avoid narrow power and ground traces to minimize inductance between the pins and the decoupling capacitors. An optional 0.1-µF supply decoupling capacitor across the two power supplies (for bipolar operation) reduces second-order harmonic distortion.
