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/µs, 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.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AMP03 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

APPLICATIONS INFORMATION
0.1F
The AMP03 represents a versatile analog building block. In
order to capitalize on fast settling time, high slew rate and high
CMR, proper decoupling and grounding techniques must be
employed. Figure 20 illustrates the use of 0.1 µF decoupling
capacitors and proper ground connections.

MAINTAINING COMMON-MODE REJECTION
In order to achieve the full common-mode rejection capability
of the AMP03, the source impedance must be carefully con-
trolled. Slight imbalances of the source resistance will result in a
degradation of DC CMR—even a 5 Ω imbalance will degrade
CMR by 20 dB. Also, the matching of the reactive source im-
pedance must be matched in order to preserve the CMRR over
frequency.
