For example, the common mode range is from 0.15V to
2.65V if the output is set at one half of the 3V supply. The
common mode rejection is greater than 110dB at 100Hz
when trimmed with resistor R1. The amplifier has a
bandwidth of 550kHz.
Single Supply, 400kHz, 4th Order Butterworth Filter
The circuit shown in Figure 2 makes use of the low voltage
operation and the wide bandwidth of the LT1632 to create
a 400kHz 4th order lowpass filter with a single supply. The
amplifiers are configured in the inverting mode to mini-
mize common mode induced distortion and the output
can swing rail-to-rail for the maximum dynamic range.
Figure 3 displays the frequency response of the filter.
Stopband attenuation is greater than 85dB at 10MHz.

RF Amplifier Control Biasing and DC Restoration
Taking advantage of the rail-to-rail input and output, and
the large output current capability of the LT1632, the
circuit shown in Figure 4 provides precise bias current for
the RF amplifiers and restores the DC output level. To
ensure optimum performance of an RF amplifier, its bias
point must be accurate and stable over the operating
