Overview
The AMP03GSZ-RL, produced by Analog Devices Inc., is a monolithic, unity-gain, high-speed differential amplifier. This component is designed as a basic analog building block for various differential amplifier and instrumentation applications. It features a matched thin film resistor network, ensuring stable operation over temperature without the need for expensive external matched components. The AMP03GSZ-RL is known for its high common-mode rejection (CMR) and is an ideal choice for applications requiring the amplification of the difference between two signals while rejecting common-mode input voltage.
