Power supply considerations and improvement of the
PSRR
Correct power supply bypassing is very important to optimize performance in low and high-
frequency ranges. Bypass capacitors should be placed as close as possible to the IC pin
(pin 4) to improve high-frequency bypassing. A capacitor (C
necessary to improve the PSRR in low frequencies. For better quality bypassing, a capacitor
of 100 nF (C
improve the noise supply rejection in the higher frequency ranges. A coil can be added in
order to better reject the noise from the supply and to prevent current peaks as much as
possible.
