AGND (Pin 2): Analog Ground. The AGND pin is at the
midpoint of an internal resistive voltage divider, develop-
ing a potential halfway between the V+ and V– pins, with an
equivalent series resistance to the pin of nominally 5k
(Figure 1). AGND is also the noninverting input to both the
internal channel A and channel B amplifiers. This makes
AGND the ground reference voltage for the INA, INB, OUTA
and OUTB pins. Recommended analog ground plane con-
nection depends on how power is applied to the LTC6911-X
(see Figures 2, 3 and 4). Single power supply applications
typically use V– for the system signal ground. The analog
ground plane in single supply applications should there-
fore tie to V–, and the AGND pin should be bypassed to this
ground plane by a high quality capacitor of at least 1
F
(Figure 2). The AGND pin provides an internal analog
reference voltage at half the V+ supply voltage. Dual supply
applications with symmetrical supplies (such as
±5V)
have a natural system ground plane potential of zero volts,
which can be tied directly to the AGND pin, making the zero
volt ground plane the input and output reference voltage
for the LTC6911-X (Figure 3). Finally, if dual asymmetrical
power supplies are used, the supply ground is still the
natural ground plane voltage. To maximize signal swing

capability with an asymmetrical supply, however, it is
often desirable to refer the LTC6911-X’s analog input and
output to a voltage equidistant from the two supply rails V+
and V–. The AGND pin will provide such a potential when
open-circuited and bypassed with a capacitor (Figure 4).
