APPLICATIONS INFORMATION
Interfacing to the LT6604-10
Note: The LT6604-10 contains two identical lters. The
following applications information only refers to one lter.
The two lters are independent except that they share
the same negative supply voltage V–. The two lters
can be used simultaneously by replicating the example
circuits. The referenced pin numbers correspond to the
channel A lter.
The LT6604-10 channel requires two equal external resis-
tors, RIN,tosetthedifferentialgainto402Ω/RIN.Theinputs
to the lter are the voltages VIN+andVIN–presentedtothese
external components, Figure 1. The difference between VIN+
and VIN– is the differential input voltage. The average of
VIN+ and VIN– is the common mode input voltage. Simi-
larly, the voltages VOUT+ and VOUT– appearing at Pins 27
and 29 of the LT6604-10 are the lter outputs. The differ-
ence between VOUT+ and VOUT– is the differential output
voltage. The average of VOUT+ and VOUT– is the common
mode output voltage. Figure 1 illustrates the LT6604-10
operating with a single 3.3V supply and unity passband
gain; the input signal is DC coupled. The common mode
input voltage is 0.5V, and the differential input voltage is
2VP-P. The common mode output voltage is 1.65V, and the
differential output voltage is 2VP-P for frequencies below
10MHz. The common mode output voltage is determined
by the voltage at VOCM. Since VOCM is shorted to VMID,
the output common mode is the mid-supply voltage. In
addition, the common mode input voltage can be equal
to the mid-supply voltage of VMID.
Figure2showshowtoACcouplesignalsintotheLT6604-10.
In this instance, the input is a single-ended signal. AC
coupling allows the processing of single-ended or dif-
ferential signals with arbitrary common mode levels. The
0.1μF coupling capacitor and the 402Ω gain setting resistor
form a high pass lter, attenuating signals below 4kHz.
Larger values of coupling capacitors will proportionally
reduce this highpass 3dB frequency.
