resistance of approximately 14k. On the LTC6404-4, the
V
V
bypass capacitor of at least 0.01μF , (unless you are using
split supplies, then connect directly to a low impedance,
low noise ground plane) to minimize common mode noise
from being converted to differential noise by impedance
mismatches both externally and internally to the IC.
NC (Pins 5, 16): No Connection. These pins are not con-
nected internally.
OUT
driving the feedback network, each pin can drive an ad-
ditional 50Ω to ground with typical short-circuit current
limiting of ±65mA. Each amplifi er output is designed to
drive a load capacitance of 10pF . This basically means
the amplifi er can drive 10pF from each output to ground
or 5pF differentially. Larger capacitive loads should be
decoupled with at least 25Ω resistors in series with each
output. For long-term device reliability, it is recommended

absolute minimum by keeping printed circuit connections
