Incorporating a matched thin-film resistor network, the AMP03 features stable operation over temperature without requiring expensive external matched components.
The AMP03 is a basic analog building block for differential amplifier and instrumentation applications.
The differential amplifier topology of the AMP03 serves to both amplify the difference between two signals and provide extremely high rejection of the common-mode input voltage.
By providing common-mode rejection (CMR) of 100 dB typical, the AMP03 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.
The large commonmode 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 AMP03 is an ideal general amplifier for buffering signals in a noisy environment into data acquisition systems.
The AMP03 is a higher speed alternative to the INA105.
Featuring slew rates of 9.
5 V/µs, and a bandwidth of 3 MHz, the AMP03 offers superior performance for high speed current sources, absolute value amplifi...
