The AMP02 is the first precision instrumentation amplifier available in an 8-pin package. It offers low offset voltage, low drift, wide gain range, high common-mode rejection, high bandwidth, accurate gain equation, single resistor gain setting, input overvoltage protection, low cost and so on. It can be widely used in differential amplifier, strain gauge amplifier, thermocouple amplifier, RTD amplifier, programmable gain instrumentation amplifier, medical instrumentation, data acquisition systems and so on.

The AMP01 is a monolithic instrumentation amplifier designed for high-precision data acquisition and instrumentation applications. The design combines the conventional features of an instrumentation amplifier with a high current output stage. The output remains stable with high capacitance loads (1 µF), a unique ability for an instrumentation amplifier. Consequently, the AMP01 can amplify low level signals for transmission through long cables without requiring an output buffer. The output stage may be configured as a voltage or current generator. Input offset voltage is very low (20 µV), which generally eliminates the external null potentiometer. Temperature changes have minimal effect on offset; TCVIOS is typically 0.15 µV/°C. Excellent low-frequency noise performance is achieved with a minimal compromise on input protection. Bias current is very low, less than 10 nA over the military temperature range. High common-mode rejection of 130 dB, 16-bit linearity at a gain of 1000, and 50 mA peak output current are achievable simultaneously.
