The MAX7409/MAX7413 Bessel filters provide low over-
shoot and fast settling responses, and the MAX7410/
MAX7414 Butterworth filters provide a maximally flat
passband response. All parts operate with a 100:1
clock-to-corner frequency ratio and a 15kHz maximum
corner frequency.
Lowpass Bessel filters such as the MAX7409/MAX7413
delay all frequency components equally, preserving the
shape of step inputs (subject to the attenuation of the

Positive Supply Input: +5V for MAX7409/MAX7410, +3V for MAX7413/MAX7414.
Filter Output
Offset Adjust Input. To adjust output offset, connect OS to an external supply through a resistive voltage-
divider (Figure 3). Connect OS to COM if no offset adjustment is needed. Refer to the
Mode Input Adjustment section.

higher frequencies). Bessel filters settle quickly—an
important characteristic in applications that use a multi-
plexer (mux) to select an input signal for an analog-to-
digital converter (ADC). An anti-aliasing filter placed
between the mux and the ADC must settle quickly after
a new channel is selected.
Lowpass Butterworth filters such as the MAX7410/
MAX7414 provide a maximally flat passband response,
making them ideal for instrumentation applications that
require minimum deviation from the DC gain throughout
the passband.
