Functional Description
The LT1567 contains two low noise rail-to-rail output,
wideband operational amplifiers, one of them connected
internally as a unity-gain inverter. These two amplifiers
can form a second order multiple feedback filter configu-
ration (Figure 1) for megahertz signal frequencies, with
exceptionally low total noise. The amplifier in the dedi-
cated inverter (INV) is optimized for better high fre-
quency linearity while the uncommitted operational
amplifier (OA) is optimized for lower input noise voltage,
addressing the different sensitivities to these effects
when used as a filter section. This combination produces
a low noise filter with better distortion performance than
would be possible with identical amplifiers.
LT1567 Free Design Software
A spreadsheet-based design tool is available at
www.linear.com for designing lowpass and bandpass
filters using the LT1567.
