AMP03GPZ Description

A high speed differential amplifier with unity gain, the AMP03GPZ is a monolithic device. The AMP03GPZ has steady functioning over temperature and does not require expensive external matched components thanks to the incorporation of a matched thin film resistor network. The AMP03GPZ is a fundamental analog building component used in instrumentation and differential amplifier applications.

The AMP03GPZ's differential amplifier topology amplifies the difference between two signals and offers extraordinarily good common-mode input voltage rejection. The AMP03GPZ addresses typical issues in instrumentation design by offering common-mode rejection (CMR) of 100 dB. The AMP03GPZ, for instance, is perfect for adding or subtracting two signals without the use of pricey externally matched precision resistors.

By matching the internal resistors to better than 0.002% and maintaining a thermally symmetric arrangement, the substantial common-mode rejection is made achievable. The AMP03GPZ is also a great general amplifier for buffering signals into data collecting systems in noisy environments due to its high CMR over frequency.

The AMP03GPZ is a faster option than the INA105. For high speed current sources, absolute value amplifiers, and summing amplifiers, the AMP03GPZ outperforms the INA105 with slew rates of 9.5 V/μs and a bandwidth of 3 MHz.
