LH0038/LH0038C True Instrumentation Amplifier
General Description
The LH0038/LH0038C is a precision true instrumentation amplifier (TIA) capable of amplifying very low level signals, such as thermocouple and low impedance strain guage outputs. Precision thin film gain setting resistors are included in the package to allow the user to set the closed-loop gain from 100 to 2000. Since the resistors are of a homogeneous single chip construction, they track almost perfectly so that temperature variations of closed loop gain are virtually eliminated.
LH0038 exhibits excellent CMRR, PSRR, gain linearity', as well as extremely low input offset voltage, offset voltage drift and input noise voltage.
