LT1168 - Low Power, Single Resistor Gain Programmable, Precision Instrumentation Amplifier
... The high accuracy of the LT1168 is due to a 20ppm maximum nonlinearity and 0.4% max gain error (G = 10). Previous monolithic instrumentation amps cannot handle a 2k load resistor whereas the nonlinearity of the LT1168 is specified for loads as low as 2k. The LT1168 is laser trimmed for very low inpu ...
