GENERAL DESCRIPTION
The AMP03 is a monolithic unity-gain, high speed differential
amplifier. 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 addi-
tion 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
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. Fea-
turing slew rates of 9.5 V/
μ
s, and a bandwidth of 3 MHz, the
AMP03 offers superior performance for high speed current
sources, absolute value amplifiers and summing amplifiers than
the INA105.
