PIN FUNCTIONS
V
EE
(Pins 1, 2): Negative Supply Voltage. V
EE
pins are not
internally connected to each other and must all be con-
nected externally. Proper supply bypassing is necessary
for best performance. See the Applications Information
section.
V
EE
(Pins 3, 7): Negative Supply Voltage for Output Stage.
V
EE
pins are not internally connected to each other and
must all be connected externally. Proper supply bypassing
is necessary for best performance. See the Applications
Information section.
NC (Pin 4): This pin is not internally connected.
OUT2 (Pin 5): Output of Channel 2. The gain between the
input and the output of this channel is set by the connection
of the channel 2 input pins. See Table 1 in Applications
Information for details.
V
CC
(Pins 6, 9): Positive Supply Voltage for Output Stage.
V
CC
pins are not internally connected to each other and
must all be connected externally. Proper supply bypassing
is necessary for best performance. See the Applications
Information section.
OUT1 (Pin 8): Output of Channel 1. The gain between the
input and the output of this channel is set by the connection
of the channel 1 input pins. See Table 1 in Applications
Information for details.
V
CC
(Pin 10): Positive Supply Voltage. V
CC
pins are not
internally connected to each other and must all be con-
nected externally. Proper supply bypassing is necessary
for best performance. See the Applications Information
section.
EN (Pin 11): Enable Control Pin. An internal pull-up resis-
tor of 46k will turn the part off if the pin is allowed to fl oat
and defi nes the pin’s impedance. When the pin is pulled
low, the part is enabled.
DGND (Pin 12): Digital Ground Reference for Enable Pin.
This pin is normally connected to ground.
IN1
+
(Pin 13): Channel 1 Positive Input. This pin has a
nominal impedance of 400kΩ and does not have an internal
termination resistor.
IN1
–
(Pin 14): This pin connects to the internal resistor
network of the channel 1 amplifi er, connecting by a 370Ω
resistor to the inverting input.
IN2
–
(Pin 15): This pin connects to the internal resistor
network of the channel 2 amplifi er, connecting by a 370Ω
resistor to the inverting input.
IN2
+
(Pin 16): Channel 2 Positive Input. This pin has a
nominal impedance of 400kΩ and does not have an internal
termination resistor.
Exposed Pad (Pin 17): The pad is internally connected to
V
EE
(Pin 1). If split supplies are used, do not tie the pad
to ground.
