LTC6601-2

66012f
Likewise, substituting the numbers for a single 5V power
supply, (V+ = 5V, V– = 0V) with VOCM = 2.5V, and R1 = R2
= 100Ω, into the above equation, the input common mode
range (VINCMR) is between the two limits:
0V ≤ VINCM ≤ 4.7V
The output common mode voltage is dened as the aver-
age of the two outputs:
VOUTCM = VOCM =
VOUT+ + VOUT–
2
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
1.1 V above V– to 1V below V+. The VOCM pin sits in the
middle of a voltage divider which sets the default mid-
supply open circuit potential.
In single supply applications, where the LTC6601 is used
to interface to an ADC, the optimal common mode input
to the ADC is often determined by the ADC’s reference. If
the ADC makes a reference available for setting the input
common mode voltage, it can be directly tied to the VOCM
pin, but must be capable of driving the input impedance of
the VOCM pin (RVOCM). This impedance can be assumed
to be connected to a mid-supply potential. If an external
reference drives the VOCM pin, it should still be bypassed
with a high quality 0.01μF or higher capacitor to a low
impedance ground plane to lter any thermal noise and
to prevent common mode signals on this pin from being
inadvertently converted to differential signals.
Noise Considerations
When comparing the LTC6601 noise to other ampliers,
be sure to compare similar specications. Competing
devices often specify noise referred to the inputs of the
amplier. The input referred voltage noise of the LTC6601-2
is 4.7nV/√Hz.
In addition to the noise generated by the amplier, the
surrounding feedback resistors also contribute noise. A
noise model is shown in Figure 5. The output spot noise
generated by both the amplier and the feedback compo-
nents is governed by the equation:
