FUNCTION
1
COM
Common Input Pin. Biased internally at midsupply. Bypass COM externally to GND with a 0.1F capacitor.
To override internal biasing, drive COM with an external supply.

GND
Ground
4
VDD
Positive Supply Input: +5V for MAX7409/MAX7410, +3V for MAX7413/MAX7414.
8
CLK
Clock Input. Connect an external capacitor (COSC) from CLK to ground: fOSC (kHz) = 30 x 103 / COSC (pF).
To override the internal oscillator, connect CLK to an external clock: fC = fCLK /100.
7
SHDN
Shutdown Input. Drive low to enable shutdown mode; drive high or connect to VDD for normal operation.
6
OS
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
Offset and Common-
Mode Input Adjustment section.

Pin Description
_______________Detailed Description
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.
Bessel Characteristics
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
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.
Butterworth Characteristics
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.
Typical Operating Characteristics (continued)
(VDD = +5V for MAX7409/MAX7410, VDD = +3V for MAX7413/MAX7414, fCLK = 100kHz, SHDN = VDD, COM = OS = VDD / 2, TA = +25°C,
unless otherwise noted.)
