LT1168CN8#PBF

LINEAR TECHNOLOGY  LT1168CN8#PBF  仪器放大器, 1个放大器, 60 µV, 30 V/µs, 400 kHz, ± 2.3V 至 ± 18V, DIP

The is a low power single resistor gain programmable Micropower Precision Instrumentation Amplifier that requires only one external resistor to set gains of 1 to 10000. The low voltage noise of 10nV/√Hz at 1kHz is not compromised by low power dissipation 350µA typical for ±15V supplies. The wide supply range of ±2.3 to ±18V allows 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 non-linearity and 0.4% max gain error G = 10. Previous monolithic instrumentation amps cannot handle a 2k load resistor whereas the non-linearity of the LT1168 is specified for loads as low as 2k. The LT1168 is laser trimmed for very low input offset voltage 40µV max, drift 0.3µV/°C, high CMRR 90dB, G = 1 and PSRR 103dB, G = 1. Low input bias currents of 250pA max are achieved with the use of superbeta processing.
