The gain options with the internal termination resistors RT
are given by the following equation and typical numbers
are summarized in Table 2. Gain values are dependent
on actual source impedance and on-chip RT, RG, and RF
values. The latter are subject to process variation.

For single-ended to differential applications where the
source impedance is 50I, such as the case of the
Typical Application Circuit, connect an external 50I
resistor at the other input to maintain symmetry and mini-
mize the gain error.
Applications Information
Input Voltage Range
One of the typical applications is the translation of a
single-ended input signal that is referenced to ground
to a differential output signal that feeds a high-speed
pipeline analog-to-digital converter (ADC) such as the
one in the Typical Application Circuit. Because the input
signal has 0V common mode, the majority of the ampli-
fiers would require a negative supply. The ICs allow the
input signal to be below ground even with single-supply
operation (VEE connected to GND). How far below
ground depends on the gain option. See the Electrical
Characteristics table and Figures 1, 2, and 3 for details.
Use the following equation to determine the input com-
mon-mode range:

where VIN_CM is the input common-mode voltage. VAMP
is the voltage at the input node of the internal amplifier.
VOUT_CM is the output common-mode voltage. G is the
gain of the device.
