Power supply decoupling
Proper supply bypassing is critical for low-noise performance and high supply voltage
ripple rejection. The respective capacitor locations should be as close as possible to
the device and grounded to the power ground. Proper power supply decoupling also
prevents oscillations.
For suppressing higher frequency transients (spikes) on the supply line a capacitor
with low ESR – typical 100 nF – has to be placed as close as possible to the device.
For suppressing lower frequency noise and ripple signals, a large electrolytic
capacitor – e.g. 1000
μ
F or greater – must be placed close to the device.
The bypass capacitor on the SVR pin reduces the noise and ripple on the midrail
voltage. For good THD and noise performance a low ESR capacitor is recommended.
