Single 3V Supply, 4MHz, 4th Order Butterworth Filter
Benefi ting from a low voltage supply operation, low
distortion and rail-to-rail output of LT1806/LT1807, a low
distortion fi lter that is suitable for antialiasing can be built
as shown in Figure 6.

On a 3V supply, the fi lter built with LT1807 has a passband
of 4MHz with 2.5V
than 70dB to frequency of 100MHz. As an option to minimize
the DC offset voltage at the output, connect a series resistor
of 365Ω and a bypass capacitor at the noninverting inputs
of the amplifi ers as shown in Figure 6.
