Noise Filtering
The LT6100 provides signal filtering via pin FIL that is
internally connected to the resistors RE and RO. This pin
may be used to filter the input signal entering the LT6100’s
internal op amp, and should be used when fast ripple cur-
rent or transients flow through the sense resistor. High
frequency signals above the 300kHz bandwidth of the
LT6100’s internal amplifier will cause errors. A capacitor
connected between FIL and VEE creates a single pole low
pass filter with corner frequency:
f–3dB = 1/(2πRFILC)
where RFIL = 60k. A 220pF capacitor creates a pole at
12kHz, a good choice for many applications.

sense amplifier output, VO1, is buffered by the internal op

preserve signal accuracy. For zero VSENSE, internal circuit
saturation with loss of accuracy occurs at the minimum
VOUT swing, 15mV above VEE. VOUT may swing positive
to within 75mV of VCC or a maximum of 36V, a limit set
by internal junction breakdown. Within these constraints,
an amplified, level shifted representation of the RSENSE
voltage is developed at VOUT. The output is well behaved
driving capacitive loads to 1000pF.
Sense Input Signal Range
The LT6100 has high CMRR over the wide input voltage
range of 4.1V to 48V. The minimum operation voltage of
the sense amplifier input is 1.4V above VCC. The output
remains accurate even when the sense inputs are driven
to 48V. Figure 2 shows that VOS changes very slightly
over a wide input range. Furthermore, the sense inputs
VS+ and VS– can collapse to zero volts without incurring
any damage to the device. The LT6100 can handle dif-
ferential sense voltages up to the voltage of the sense
inputs supplies. For example, VS+ = 48V and VS– = 0V can
be a valid condition in a current monitoring application
(Figure 3) when an overload protection fuse is blown and
VS– voltage collapses to ground. Under this condition, the
output of the LT6100 goes to the positive rail, VOH. There
is no phase inversion to cause an erroneous output signal.
For the opposite case when VS+ collapse to ground with
VS– held up at some higher voltage potential, the output
will sit at VOL. If both inputs fall below the minimum CM
voltage, VCC + 1.4V, the output is indeterminate but the
LT6100 will not be damaged.
