Linear Technology LT1168
the LT1168 to fit into a wide variety of industrial as well as battery-powered applications. The high accuracy of the LT1168 is due to a 20ppm maximum nonlinearityand0.4%maxgainerror(G=10).Previousmonolithic 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 input offsetvoltage(40µVmax),drift(0.3µV/°C),highCMRR(90dB, G = 1) and PSRR (103dB, G = 1).| Part No. | LT1168 |
