AMP03GP

The AMP03GP is a precision, unity-gain differential amplifier manufactured by Analog Devices. It incorporates a matched thin-film resistor network, enabling stable operation over temperature without the need for external matched components. This device serves as a fundamental analog building block for differential and instrumentation amplifier applications.

The amplifier's topology amplifies the difference between two signals while providing high rejection of common-mode input voltage, achieving a typical Common Mode Rejection Ratio (CMRR) of 100 dB. This makes it suitable for applications requiring precise signal amplification in noisy environments. The AMP03GP offers a wide bandwidth of 3 MHz and a fast slew rate of 9.5 V/ms, making it a higher-speed alternative to other devices like the INA105.

Key electrical characteristics include low nonlinearity of 0.001% maximum and low distortion of 0.001% typical. It also features a fast settling time of 1 ms to 0.01%. The device is available in an 8-lead package, suitable for various instrumentation and signal processing designs.

Applications for the AMP03GP include summing amplifiers, instrumentation amplifiers, balanced line receivers, current-to-voltage conversion, absolute value amplifiers, and 4 mA–20 mA current transmitters. Its robust performance and integrated resistor network simplify design and reduce component count.
