9 Power Supply Recommendations

The OPA541 is specified for operation from power supplies up to ±40 V. The OPA541 can also be operated from unbalanced power supplies or a single power supply, as long as the total power supply voltage does not exceed 80 V. The power supplies should be bypassed with low series-impedance capacitors such as ceramic or tantalum. These must be located as near as practical to the power supply pins of the amplifier. Good power amplifier circuit layout is, in general, similar to good high-frequency layout: consider the path of the large power supply and output currents and avoid routing these connections near low-level input circuitry to avoid waveform distortion and oscillations.
