APPLICATIONS INFORMATION

Input Common Mode Voltage Range
The LTC6404’s input common mode voltage (VICM) is
dened as the average of the two input voltages, VIN+, and
VIN–. It extends from V– to 1.4V below V+. The operating
input common mode range depends on the circuit con-
guration (gain), VOCM and VCM (Refer to Figure 5). For
fully differential input applications, where VINP = –VINM,
the common mode input voltage is approximately:

With singled ended inputs, there is an input signal com-
ponent to the input common mode voltage. Applying only
VINP (setting VINM to zero), the input common voltage is
approximately:

Output Common Mode Voltage Range
The output common mode voltage is dened as the aver-
age of the two outputs:
VV

The VOCM pin sets this average by an internal common
mode feedback loop which internally forces VOUT+=–VOUT–.
The output common mode range extends from 1.1V above
V– to 1V below V+ (see the Electrical Characteristics table
for the LTC6404-4 output common mode voltage range).
The VOCM pin sits in the middle of a voltage divider which
sets the default mid-supply open circuit potential.
