10 Power Supply Recommendations

The OPA690 is principally intended to work in a supply range of ±2.5 V to ±6 V. Good power-supply bypassing is required. Minimize the distance (< 0.1 inch) from the power-supply pins to high frequency, 0.1-µF decoupling capacitors. Often a larger capacitor (2.2 µF is typical) is used along 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 somewhat farther from the device and share these capacitors among several devices in the same area of the PCB.

Avoid narrow power and ground traces to minimize inductance between the pins and the decoupling capacitors. An optional supply decoupling capacitor across the two power supplies (for bipolar operation) improves second harmonic distortion performance.
