AMP03GSZ (ANALOG DEVICES)

The AMP03GSZ is a Precision Unity Gain Differential Amplifier incorporates a matched thin film resistor network. It is a basic analogue building block for differential amplifier and instrumentation applications. The differential amplifier topology 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 100dB typical, it solves common problems encountered in instrumentation design. As an example, the AMP03 is ideal for performing either addition or subtraction of two signals without using expensive externally matched precision resistors. Due to high CMR over frequency, the AMP03 is an ideal general amplifier for buffering signals in a noisy environment into data acquisition systems. Featuring slew rates of 9.5V/µs and a bandwidth of 3MHz, the AMP03 offers superior performance to the INA105 for high speed current sources, absolute value amplifiers and summing amplifiers.
