PIN FUNCTIONS
VOCM (Pin 2/Pin 4): Output Common Mode Reference
Voltage. The voltage on VOCM sets the output common
mode voltage level (which is dened as the average of the
voltages on the +OUT and –OUT pins). The VOCM voltage
is internally set by a resistive divider between the supplies,
developing a default voltage potential of 2.5V with a 5V
supply. The VOCM pin can be over-driven by an external
voltage capable of driving the 19kΩ Thevenin equivalent
impedance presented by the pin. The VOCM pin should be
bypassed with a high quality ceramic bypass capacitor of at
least 0.01μF, to minimize common mode noise from being
converted to differential noise by impedance mismatches
both externally and internally to the IC.
V+ (Pin 3/Pins 2, 10, 11):
V– (Pin 6/Pins 3, 9, 12):
Power Supply Pins. It is critical that close attention be
paid to supply bypassing. For single supply applications,
it is recommended that a high quality 0.1μF surface mount
ceramic bypass capacitor be placed between V+ and V– with
direct short connections. In addition, V– should be tied
directly to a low impedance ground plane with minimal
routing. For dual (split) power supplies, it is recommended
that additional high quality, 0.1μF ceramic capacitors are
used to bypass V+ to ground and V– to ground, again
with minimal routing. For driving large loads (<200Ω),
additional bypass capacitance may be needed for optimal
performance. Keep in mind that small geometry (e.g., 0603
or smaller) surface mount ceramic capacitors have a much
higher self resonant frequency than do leaded capacitors,
and perform best in high speed applications.
+OUT, –OUT (Pins 4, 5/Pins 7, 14): Unltered Output
Pins. Besides driving the feedback network, each pin
can drive an additional 50Ω to ground with typical short
circuit current limiting of ±60mA. Each amplier output
is designed to drive a load capacitance of 5pF. Larger
capacitive loads should be decoupled with at least 15Ω
resistors from each output.
VTIP (Pin 5) QFN Only: This pin can normally be left oat-
ing. It determines which pair of input transistors (NPN or
PNP or both) is sensing the input signal. The VTIP pin is
set by an internal resistive divider between the supplies,
developing a default 2.8V voltage with a 5V supply. VTIP
has a Thevenin equivalent resistance of approximately
17k and can be over-driven by an external voltage. The
VTIP pin should be bypassed with a high quality ceramic
bypass capacitor of at least 0.01μF. See the Applications
Information section for more details.
SHDN (Pin 7/Pin 1): When SHDN is oating or directly
tied to V+, the LTC6405 is in the normal (active) operat-
ing mode. When the SHDN pin is connected to V–, the
LTC6405 enters into a low power shutdown state with
Hi-Z outputs.
+IN, –IN (Pins 8, 1/Pins 15, 6): Noninverting and Inverting
Input Pins of the Amplier, Respectively. For best perfor-
mance, it is highly recommended that stray capacitance
be kept to an absolute minimum by keeping printed circuit
connections as short as possible.
+OUTF, –OUTF (Pins 8, 13) QFN Only: Filtered Output
Pins. These pins have a series RC network (R = 50Ω,
C = 3.75pF) connected between the ltered and unltered
outputs. See the Applications Information section for
more details.
NC (Pin 16) QFN Only: No Connection. This pin is not
connected internally.
Exposed Pad (Pin 9/Pin 17): Tie the bottom pad to V–. If
split supplies are used, DO NOT tie the pad to ground.
