LTC6373 Instrumentation Amplifiers

Analog Devices Inc. LTC6373 Instrumentation Amplifiers are precision instrumentation amplifiers with fully differential outputs. These outputs include a closely matched 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 maintains nearly the same bandwidth across all its gain settings.
