MAX9890
Switches
The MAX9890’s internal switches connect the input to the
output after the coupling capacitors are fully charged.
The MAX9890A holds the switches open for 200ms and is
ideal for coupling capacitors less than 100F. The
MAX9890B has a longer turn-on time of 330ms and is
ideal with larger coupling capacitors less than 220F. The
internal switches have a low on-resistance (RON = 0.5
Ω)
and on-resistance flatness (RFLAT(ON) = 2m
Ω) minimizing
total harmonic distortion plus noise (THD+N). The rela-
tionship below shows the contribution to THD+N through
the switch, due to on-resistance and on-resistance flat-
