requiring expensive external matched components. The AMP03
V– 4 5 SENSE
is a basic analog building block for differential amplifier and

instrumentation applications.
8-Lead SOIC
The differential amplifier topology of the AMP03 both amplifies the difference between two signals and provides extremely high
(S Suffix)
rejection of the common-mode input voltage. By providing common-mode rejection (CMR) of 100 dB typical, the AMP03
REFERENCE 1 8 NC AMP03
solves common problems encountered in instrumentation design.
–IN 2 7 V+ TOP VIEW
As an example, the AMP03 is ideal for performing either addi-
+IN 3 (Not to Scale) 6 OUTPUT
tion or subtraction of two signals without using expensive
V– 4 5 SENSE
externally matched precision resistors. The large common-mode
NC = NO CONNECT
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
(J Suffix)
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.
