where RIN is a minimum of 10k
Ω. Choose CIN such that
f-3dB is well below the lowest frequency of interest.
Setting f-3dB too high affects the amplifier’s low-frequen-
cy response. Use capacitors with low-voltage coefficient
dielectrics. Film or C0G dielectric capacitors are good
choices for AC-coupling capacitors. Capacitors with
high-voltage coefficients, such as ceramics, can result in
increased distortion at low frequencies.
Charge-Pump Flying Capacitor
The charge-pump flying capacitor connected between
C1N and C1P affects the charge pump’s load regula-
tion and output impedance. Choosing a flying capacitor
that is too small degrades the MAX9723’s ability to pro-
vide sufficient current drive and leads to a loss of out-
put voltage. Increasing the value of the flying capacitor
improves load regulation and reduces the charge-
pump output impedance. See the Output Power vs.
