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 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 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 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.
Featuring slew rates of 9.5 V/µs and a bandwidth of 3 MHz, the
AMP03 offers superior performance to the INA105 for high
speed current sources, absolute value amplifiers, and summing
amplifiers.

accumulate on the human body and test equipment and can discharge without detection.
Although the AMP03 features proprietary ESD protection circuitry, permanent damage may

APPLICATIONS INFORMATION
The AMP03 represents a versatile analog building block. In
order to capitalize on the fast settling time, high slew rate, and
high CMR, proper decoupling and grounding techniques must
be employed. Figure 1 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 controlled. 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
impedance must be matched in order to preserve the CMRR
over frequency.
