Power supply considerations
TSH345
Correct power supply bypassing is very important for optimizing 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 (CLF) greater than 100 µF is
necessary to improve the PSRR in low frequencies. For better quality bypassing, you can
add a capacitor of 470 nF (CHF), also placed as close as possible to the IC pin, to improve
the PSRR in the higher frequencies.
