PIN FUNCTIONS
–IN (Pin 1/Pin 1): Negative Sense Input Terminal.
Negative sense voltage input will remain functional for
voltages up to 44V, referred to V–. Connect –IN to an
external gain-setting resistor RIN1 (RIN1 = RIN2) to set
the gain.
V+ (Pin 2/Pin 2):
Power Supply Voltage. This pin supplies
current to the amplier and can operate from 2.85V to 36V,
independent of the voltages on the –IN or +IN pins.
V– (Pin 3/Pin 4):
Negative Power Supply Voltage or Ground
for Single Supply Operation.
VOUT (Pin 4/Pin 5): Voltage Output:
VOUT = AV (VSENSE ± VOS)
VOS is the input offset voltage. AV is the gain set by exter-
nal RIN1, RIN2, ROUT. AV = ROUT/RIN1, for RIN1 = RIN2.
NC (Pin 5/Pins 3, 6, 7): Not Connected Internally.
+IN (Pin 6/Pin 8): Positive Sense Input Terminal.
Connecting a source to VS+ and a load to VS– will allow the
LT6105 to monitor the current through RSENSE, refer to
Figure 1. Connect +IN to an external gain-setting resistor
RIN2 to set the gain. +IN remains functional for voltages
up to 44V, referred to V–.
Exposed Pad (Pin 7) DFN Only: V–. The Exposed Pad is
connected to the V– pin. It should be connected to the
V– trace of the PCB, or left oating.
