SHDN (Pin 1/Pin 7): When SHDN is oating or directly
tied to V+, the LTC6406 is in the normal (active) operat-
ing mode. When the SHDN pin is connected to V–, the
LTC6406 enters into a low power shutdown state with
Hi-Z outputs.
V+, V– (Pins 2, 10, 11 and Pins 3, 9, 12/Pins 3, 6): 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 (<200
Ω),
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.
VOCM (Pin 4/Pin 2): 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 1.25V with a 3V
supply. The VOCM pin can be overdriven by an external
voltage capable of driving the 18k
Ω 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.
VTIP (Pin 5/NA): This pin can normally be left oating.
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 1.55V voltage with a 3V supply. VTIP
has a Thevenin equivalent resistance of approximately
15k and can be overdriven 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.
+OUT, –OUT (Pins 7, 14/Pins 4, 5): Unltered Output
Pins. Besides driving the feedback network, each pin
can drive an additional 50
Ω to ground with typical short-
circuit current limiting of ±55mA. Each amplier output
