*TO OPTIMIZE THE HIGH FREQUENCY PERFORMANCE FOR THE PIN CONFIGURATION OF THE LTC6405
IN THE SMALL MSOP PACKAGE, A FEEDBACK RESISTANCE OF AT LEAST 300Ω IS RECOMMENDED.

The outputs (+OUT and –OUT) of the LTC6405 are capable
of swinging from close-to-ground to typically 1V below
V+. They can source or sink up to approximately 60mA of
current. Each output is designed to directly drive up to 5pF
to ground. Higher load capacitances should be decoupled
with at least 15Ω of series resistance from each output.
Input Pin Protection
The LTC6405 input stage is protected against differential
input voltages which exceed 1.4V by two pairs of series
diodes connected back to back between +IN and –IN. In
addition, the input pins have clamping diodes to either
power supply. If the input pins are over-driven, the current
should be limited to under 10mA to prevent damage to the
IC. The LTC6405 also has clamping diodes to either power
supply on the VOCM, VTIP and SHDN pins and if driven to
voltages which exceed either supply, they too, should be
current limited to under 10mA.
SHDN Pin
The SHDN pin is a CMOS logic input with a 50k internal
pull-up resistor. If the pin is driven low, the LTC6405 powers
down with Hi-Z outputs. If the pin is left unconnected or
driven high, the part is in normal active operation. Some
care should be taken to control leakage currents at this pin
to prevent inadvertently putting the LTC6405 into shutdown.
The turn-on and turn-off time between the shutdown and
active states are typically less than 1μs.
