Product Summary
The AMP03BJ is a monolithic unity-gain, high speed differential amplifier. Incorporating a matched thin film resistor network, the AMP03BJ features stable operation over temperature without requiring expensive external matched components. The device is a basic analog building block for differential amplifier and instrumentation applications. The differential amplifier topology of the AMP03BJ both amplifies the difference between two signals and provides extremely high rejection of the common-mode input voltage. By providing common-mode rejection (CMR) of 100 dB typical, it solves common problems encountered in instrumentation design. As an example, the AMP03BJ is ideal for performing either addition or subtraction of two signals without using expensive externally matched precision resistors. The large common-mode rejection is made possible by matching the internal resistors to better than 0.002% and maintaining a thermally symmetric layout. Additionally, due to high CMR over frequency, the AMP03BJ is an ideal general amplifier for buffering signals in a noisy environment into data acquisition systems.
