Burr-Brown's integrated circuit
Type UAF42 is a generalpurpose
active filter that may
be used as a high-pass, a lowpass,
a band-pass, or a bandstop
secnon. It is designed in
the traditicnal stare-variable
architecture witb an inverting
arnplifier and two iruegrators.
The 1000 pF ±0.5% integrator
capacitcrs are on the chip,
which makes looking for such
loss-free, high-precision devices
unnecessary.
