RA201

~National ~ Semiconductor Precision .Networks RA201 Precision Instrumentation Amplifier Resistor Network General Description The RA201 is a family of precision instrumentation amplifier networks. This device, when combined with 3 operational amplifiers, provides a precision instrumentation amplifier with common-mode rejection up to· 100 dB. All gain setting resistors are provided within the device. This feature assures excellent thermal tracking _ and thermal matching of all resistors. This network is manufactured using a high stability thin-film technology. Thin-film resistors provide tracking temperature coefficients of better than 5 ppmt~_ The thin-film resistors are laser trimmed to guarantee resistor matching to 0.05% for the RA201-2, and 0.1% for the RA201-1. Other applications include process control interfacing and precision decade dividers. Features Gain programmable Matching accuracies to 0.05% Matching temperature coefficient to. 5 ppmtC Absolute temper...
