n Small 12-Lead 4mm × 4mm DFN (LFCSP) Package The LTC®6373 is a precision instrumentation amplifier
with fully differential outputs which includes a closelymatched internal resistor network to achieve excellent
CMRR, offset voltage, gain error, gain drift, and gain nonlinearity. The user can easily program the gain to one
of seven available settings through a 3-bit parallel interface (A2 to A0). The 8th state puts the part in shutdown
which reduces the current consumption to 220μA. Unlike
a conventional voltage feedback amplifier, the LTC6373 …
