Overview:

The LTC6373SDFM is a precision instrumentation amplifier with a fully differential output. These outputs include a closely matched internal resistor network for excellent CMRR, offset voltage, gain error, gain drift, and gain nonlinearity. Users can easily set the gain to one of the seven available Settings via a 3-bit parallel interface (A2 to A0). The eighth state puts the device in the off state, reducing current consumption to 220μA. Unlike conventional voltage feedback amplifiers, the LTC6373 maintains nearly the same bandwidth across all of its gain Settings.

The LTC6373 instrumentation amplifier has a fully differential output to drive a high-performance, differential input ADC. The output common-mode voltage can be adjusted independently by the VOCM pin. The LTC6373's high impedance input, DC accuracy, low noise, low distortion, and high-speed differential ADC drivers make it ideal for optimizing data acquisition systems.
